General description REFER TO SECTION 10 FOR SAFETY AND EMC RELATED ITEMS FIRST The MC 11 AC EB-2 19" power supply cabinet with external bus has 11 free slots for TKH Security plug-in modules (7TE), supplying these with the correct DC voltages. The 'mains' power connector module in the remaining, dedicated slot 0 contains a microprocessor. This processor is used for: - status monitoring and controlling of SNM compatible modules and those from the AWS 3000 series in the cabinet; - controlling two relays; - reading status information of the cabinet proper. Two RS-485 serial bus interfaces to the processor are provided, allowing remote system management and control. By way of these interfaces, a large number of MC XX EB-2 cabinets may be linked with shielded 4(+1 ground)-wire data cable. More information on system control can be found in supplementary manuals; the cabinet can be set to EB compatibility. The 230 or 120 Vac-powered MC 11 AC EB-2 internals are cooled with two fans. Note that the cabinet mounting brackets can be put on the module side or on the fan side (see figures 1a,b). 2. Indicators and connectors In figure 1a, SLOT 0-SLOT 11 indicate the twelve Siqura 2017 Version f MC11AC EB-2 (MW10) module slots. An external earthing point (1) is provided on one shorter cabinet side. The front panel of the controller module has two 9-pin D-connectors for serial (external) communications, and two 2-pin relay connections 1 and 2 combined into one connector (see figures 1a, c and table 1). The controller module front panel furthermore provides a mains connector and an access panel for the mains fuse (figures 1a,c and 4).

Choose the mode of operation (EB-2 absolute addressing, EB-2 local addressing, or EB compatibility mode, see 5). 2. Mount the MC 11 EB-2 cabinet into a standard 19-inch rack, without modules in the slots. Check whether the specified power voltage of the cabinet matches the local power supply voltage.

2 Note: to prevent overheating of the cabinet and inserted modules, provide air circulation room at the cabinet front and rear (10 cm) and bottom (1 cm). 3. The chassis should be connected to safety ground utilising the connection on the side wall of the cabinet (1 in figure 1a). 4. Fasten the power cord to the strain relief stud (see the hexagons in figures 1a and c, top). 5. Connect the power cord to the power supply and switch on power. The electric fans should be working; if not, disconnect power immediately and check the power voltage. 6. Power off the cabinet and install the TKH Security modules according to the instructions given in the user manuals of the modules. Slots not in use should be covered with 7TE blanking plates (BF 07). 7. Power on the cabinet. Both fans should be working, blowing outwards. 4. Care, maintenance and safety For reliable operation of the module, observe the following: - prevent dust from collecting on the equipment - protect the equipment against moisture - maintain sufficient cooling space around the equipment (see 3). - replace the electric fans every 5 years. Consult section 7 on how to replace fans. - replace blown fuses only with the types specified. Consult section 8 on how to change fuses. For ultimate safety, one should not remove, add or exchange modules while the power supply cabinet is operating. If a module causes a DC short on the secondary (output) side, the MC 11 will turn itself off; it can be restarted by taking power off for at least 4 seconds, then connecting it again. 5. Configuring the cabinet 5.1. General There are two basic operating modes: SNM (also loosely called EB-2) and EB (the latter providing compatibility with the older EB protocol; for EB ON Figure 2. Dip switches on the EB-2 controller board (details left out for clarity) ON DIP SWITCH BANK configuration see 5.3). Dip switches are used to set modes and parameters, which are not identical for the two modes. The dip switches for setting the parameters of MC 11 EB-2 cabinets are located on the board inside the module in the dedicated slot 0 (the EB-2 board: see figures 1a and 2). If the cabinet is already installed and filled with modules, these switches may be accessed - after powering off - by removing the modules from the first three or four adjoining slots. The position of switch no. 8 determines whether the module is in EB-2 or in EB mode (see table 2) SNM (EB-2) mode In SNM (EB-2) mode, the RS-485 transmission speed is fixed at 19.2 kbaud. The address (1-31) of the EB-2 module must be set if this module is to use EB-2 local addressing mode. These address switch settings are listed in table 3. Switch Set(s) 1-5 EB-2 address if set to local addressing using dip switches (see table 5) 6&7 off-off: EB-2 absolute addressing 6&7 on-off: EB-2 local (manual) addressing 8 compatibility mode: must be 0 (off) for EB-2 Table 2.

SNM/EB-2 programming is taught in the SNM/EB-2 Programming Manual. 6. D-connector pin assignments The pin assignments of the 9-pin D-connectors are given in table 6 below. In EB-1 mode, only the leftmost D-connector (front view) is active. Pin Description 1 not connected 2 B tx' inverting output o (- out) 3 A tx' non-inverting output o (+ out) 4 B rx' inverting input o (- in) 5 A rx' non-inverting input o (+ in) 6 not connected 7 not connected 8 not connected 9 not connected Table 6. Pin assignment of the 9-pin D connectors 7. Replacing the electric fans (Qualified service personnel only) The two electric fans must be changed every five years (replacements may be obtained from TKH Security). The procedure for mounting a new fan is as follows (see also figure 3): 1. Power down the MC 11 EB-2 cabinet and wait >3 minutes. 2. Remove the black cover with the mounted fans. 3. Disconnect fans to be replaced from their power supplies (see figure 3: these two connectors sit side by side). Since the wires run between circuit board and panel, it will usually be necessary to loosen the screws holding the wires in the connectors. Do not disconnect the wires of the similarly shaped, single mains voltage connector at the opposite corner of the board. 4. Remove disconnected fans and replace them with new ones. Make certain the blowing direction is outwards. Please use the washers and nuts as indicated for one of the fastening screws. 5. Reconnect the fan power supply wires, observing correct polarities. Tighten the screws carefully. 6. Replace the cover. 7. Reconnect the power cabinet to the mains. Check whether the fan is blowing outwards. 8. Replacing and checking the primary fuses 1. Power down the MC EB-2 cabinet by disconnecting it from the power supply. 2. The primary fuse (1 in figure 4) is located right under the mains socket. Table 7 lists fuse data. 1 supply wires to second fan 1 2 circuit board Figure 3. Replacing a fan (view from above, left fan). A fan's power connector has two fastening screws for the fans' power supply wires; polarities are indicated on the circuit board. Figure 4.
