2 INSTALLATION 1. Unpack the Q7750A Excel 10 Zone Manager. Report any damage to a Honeywell Representative. Installing the Mounting Base To install the mounting base, remove it from the Q7750A Excel 10 Zone Manager housing. 1. Remove the front cover of the Q7750A Excel 10 Zone Manager by pressing in and down on the plastic ridges located on the front and center of the device. See Fig Separate the housing from the mounting base. See Fig. 4. NOTES: Be aware of the rubber grommet under the device housing that holds the brass screw in place. Where Electro-Magnetic Interference (noise) emissions must be considered, install the Q7750A Excel 10 Zone Manager in a ring cabinet that is earth grounded. There are two ways to install the mounting base: 1. On standard EN DIN rail, 1-3/8 by 9/32 in. (35 by 7.5 mm), which is fastened with screws to a vertical surface. (Type of screws used such as sheet metal, selftapping or thread forming and the screw lengths are determined by the type of mounting material at the job site.) 2. By fastening the mounting base, with screws, directly to a vertical surface. Fig. 2. Open cover. 2. Remove the special metal tool located near the bottom of the housing. See Fig. 3. Fig. 3. Take out tool. Fig. 4. Remove brass screw, and loosen and remove Q7750A Excel 10 Zone Manager housing from mounting base

3 To mount the base to standard DIN Rail: 1. Attach two DIN rails, which are a minimum of 6 in. (155 mm) in length, with appropriate screws for the mounting surface. Space the two DIN rails 4-7/8 in. (124 mm) apart, measured from the top of each DIN Rail, while keeping them both horizontal and parallel. See Fig. 5. Fig. 7. Position and secure mounting base. Fig. 5. Attach DIN rails. 2. Loosen the metal screw on the bottom of the mounting base and hang the mounting base on the DIN rails using the plastic flanges located on the back of the mounting base. See Fig. 6. To mount the base using screws: 1. Orient the mounting base vertically on the mounting surface. Using the three screw holes (two located at the bottom corners of the base and one at the top center), mark the positions for the three no. 8 (4.0 mm) mounting screws. After the positions are marked, attach the base to the surface with the appropriate mounting screws. See Fig. 8. Fig. 6. Hang mounting base into place. 3. Slide the metal screw up against the lower flange of the bottom DIN rail and tighten the screw. See Fig. 7. Fig. 8. Attach mounting base with screws. NOTE: Wiring must enter the mounting base from the bottom; to prepare wire access holes:

4 1. Break off one or two of the plastic tabs just left of the metal screw on the mounting base for wiring access and routing to the lower left terminal block. See Fig. 9. Power Wiring Input Power: 24 Vac, 50/60 Hz. Wire 24 Vac power using the heaviest gauge UL level IV or plenum rated UL level IV wire available, up to 14 AWG (2.0 mm 2 ) with a minimum of 18 AWG (1.0 mm 2 ) wire. For nonplenum, open areas, run cables exposed (or in conduit if required; see the following NOTES). NOTES: The Q7750A Excel 10 Zone Manager must have a dedicated transformer/power source. Do not power any accessories with the Q7750A Excel 10 Zone Manager transformer/power source. Keep the transformer/power source as close as possible to the Q7750A Excel 10 Zone Manager so the power wiring will be as short as possible; the maximum length is 6 ft. 6 in. (2m). (US only) When using a 24 Vac transformer larger than 100 VA, Class II power requirements will be exceeded and the power wiring must be enclosed in conduit. Fig. 9. Break off plastic tabs for wiring access to lower left terminal block. Wiring NOTES: All wiring must comply with applicable electrical codes and ordinances. Refer to job drawings or manufacturer s drawings for details. All wiring terminals are located on the inside of the front cover. Pass all wires through the appropriate holes from the broken plastic tabs (see Fig. 9). Route wires and tie-wrap according to Fig. 12. CAUTION Make certain no line power is applied to the transformer/power source to prevent device from being attached with power on. Mounting base power must remain off until installation and wiring is checked by a control system representative. 1. Connect 24 Vac secondary side of the transformer/power source to terminals 1 and 2 on the mounting base according to job drawings. See Fig. 10. C-Bus Wiring Wire the C-Bus using cable according to Table Connect the C-Bus cable by attaching the shield to terminal 18, the positive lead to terminal 16 and the negative lead to terminal 17 according to job drawings. See Fig. 10. E-Bus Wiring Wire the E-Bus using Level IV 22 AWG (Belden part number 9D220150) or plenum-rated level IV 22 AWG (Belden part number 9H ) nonshielded, twisted pair, solid conductor wire, as the recommended wire. When possible, use Honeywell AK3781, AK3782, AK3791, or AK3792 cable (US part numbers). For additional information regarding E-Bus wiring see E-Bus Wiring Guidelines, form number Table 1. C-Bus cable types. Maximum baud rate Cable type Description Remarks 76.8K JY (St) Y 2x2x0.8 shielded, twisted pair AK3702 unshielded, twisted pair US only AK3740a shielded US only 921.6K Belden 9842 twisted pair Belden 9841 shielded US only AK3702 unshielded, twisted pair US only AK3740A shielded US only

5 1. Connect the E-Bus wire by attaching one lead to terminal 5 and the other lead to terminal 6 according to job drawings. See Fig. 9. IMPORTANT For 2000-series devices the E-Bus must be wound one turn through a ferrite cylinder (supplied with the device) a maximum of 7/8 in. (20 mm) from the housing. See Fig. 10. NOTES: The E-Bus is insensitive to polarity, eliminating installation errors due to miswiring. To minimize EMI noise, do not run Triac output wires in the same conduit as the input wires or the E-Bus communications loop. Unswitched 24 Vac power wiring can be run in the same conduit as the E-Bus cable. 2. If a Q7750A 1000-series device is located at one end of the E-Bus network, activate a termination network by placing two wires (optional jumpers) between terminals 4 and 5 and between terminals 6 and 7 (see Fig. 10). For a 2000-series device there are internal termination circuits for both a singly-terminated network topology (jumper between terminals 4 and 5 and between termninals 6 and 7) and for a doubly-terminated bus topology (jumper between terminals 3 and 5 and between terminals 6 and 8). See Fig. 11. Fig. 10. Wiring connections (1000-series E-Bus details). Fig Series E-Bus details. 3. If an XDM506 modem submodule is being used, attach the modem wiring to the appropriate terminals (9 through 18) on the mounting base. See Fig. 10. After wiring is routed, insert the tie-wraps into the holes located near the center of the mounting base. See Fig

6 Completing the Installation 1. Before mounting the Q7750A Zone Manager, turn over the device housing and remove the Philips screw located at the bottom (remove brass screw/grommet, battery and shipping tab). Separate the two parts of the device housing. See Fig. 13. NOTE: Be aware of the brass standoff located on the bottom between the circuit board and the top of the device housing. (This connects the shielding between the two parts of the device housing.) Fig. 12. Route wire and tie-wrap Fig. 13. Separate two parts of device housing (DIP switch for future use)

7 2. Attach the XD505A or the XD508 C-Bus communications submodule or the XDM506 modem submodule, which was ordered with the Q7750A, to the male and female connectors on the device circuit board. CAUTION C-Bus submodule connectors are not keyed; make sure that the male and female connections are not misaligned to prevent damage to the C-Bus submodule. 3. Press firmly down on the submodule. See Fig. 14. Reassemble the device housing by connecting the two parts of the device housing and replacing the brass screw/grommet, battery and shipping tab. 4. Verify the integrity of all the mounting base wiring. Fig. 14. Attach submodule and reassemble device housing. Secure the housing assembly to the Mounting Base 1. After all mounting base wiring is checked, carefully align the device housing over the mounting base, and push firmly on the housing device to secure it to the mounting base. Tighten the brass screw. See Fig. 15. Fig. 15. Attach device housing to mounting base

8 Install the Battery Included with the device is a 3V Lithium battery, CR 1/2 AA, VARTA number 6127 or equivalent. This battery, when new, provides one month backup of RAM and the Real Time Clock. 1. When shipped from the factory, the battery has a shipping tab between the battery positive (+) terminal and the device terminal. Remove the shipping tab during commissioning of the device. (Check and observe the polarity marked on the housing and the battery; reverse if necessary.) See Fig. 16. NOTES: When the battery is removed during a loss of input power, RAM data is lost and the device must be redownloaded. Q7750A device is located at one end of the E-Bus network, check to determine if the termination network was activated by placing two wires (optional jumpers) between the following terminal pairs. See Fig. 11: 4,5 and 6,7 (singly-terminated network) 3,5 and 6,8 (doubly-terminated network) C-Bus shield. Be sure that the C-Bus shield is attached to terminal 18, the positive lead to terminal 16, and the negative lead to terminal 17 according to job drawings. See Fig. 10. Check to see that the ferrite ring is in place on the E-Bus (see Fig. 11). NOTE: All wiring must comply with applicable electrical codes and ordinances. Refer to job or manufacturer drawings for details. Fig. 16. Remove battery shipping tab during device commissioning. CHECKOUT Step 1. Wiring Connections Inspect all wiring connections at the Q7750A terminals, and verify compliance with job drawings. If any wiring changes are required, first be sure to remove power from the controller before starting work. Pay particular attention to: 24 Vac power connections. Verify that when there are multiple Q7750A Excel 10 Zone Managers, each one has a dedicated transformer/power source, with the transformer secondary connected to terminals 1 and 2 on the mounting base, according to job drawings. See Fig. 10. E-Bus wires. Be sure that the E-Bus wires are attached to terminals 5 and 6 according to job drawings. If the Fig. 17. Q7750A Excel 10 Zone Manager LED locations

Step 2. Initial Power Up Apply power to the Q7750A. When the Q7750A receives power, the LEDs should appear in normal (uncommissioned and not downloaded) condition according to Table 2. NOTE: LED 7 is used to display E-Bus network activity. In 1000-series devices it flickers with data being transmitted or received, but in 2000-series devices it flickers only with data being received. If the status is not correct, push the reset button. Verify that the LED status is correct before proceeding. IMPORTANT The CPU reset button deletes the application program in the CPU (stored in RAM). If the reset button is pushed when the CPU contains an application, the device must be redownloaded. Step 3. Commissioning The Zone Manager CPU can be commissioned (given a C- Bus address) using an operator terminal such as the XI581 (on the PC that has the XI584 software and/or CARE installed). This operation is performed the same as for other C-Bus controllers. The following steps describe the most common procedure using the PC to commission the CPU just before downloading from the XI584. As for other C-Bus controllers, commissioning is required only after an initial power-up or if the CPU reset button was pushed. The following steps assume the Zone Manager Plant and Controller are configured in CARE (see Data File Setup section): 1. Connect the PC COM port to the Zone Manager B-port using the XW565 (or XW566) prefabricated cable. 2. Start XI584. Sign on and run XI581. Assign the controller number using the procedure for C-Bus devices (see the XI584 User's Guide, form number ). 3. Select Continue again, and select Request Download. The operator terminal should then display. Please Execute Download. 4. Select Utilities and drop down to the item File Transfer/Download. Click on All and initiate the Download. Commissioning is complete. The B-port Transmit and B-port Receive LEDs on the Zone Manager should start blinking rapidly, indicating communication between the PC and the Zone Manager. Any Download errors or connecting problems appear in the Download Results list box. A loss of communication with the B-port during downloading generates an alarm after three minutes. Press Enter and try again to download. If there is trouble establishing communication between the PC and the Zone Manager, check the following items: XW565 cable connections. That the XW565 cable is connected to the same PC COM port as selected in the CARE Download System Settings menu. IMPORTANT Carefully watch all C-Bus alarm activity following a download. Follow up as necessary on all problem alarms. Fig. 18. Connect operating device
