13 Installation 4 Installation 4.1 Mounting the RAYMAPB Terminal Box The mounting dimensions for the RAYMAPB are shown on Figure 4. When mounting the RAYMAPB allow clearance for cable entry and cable fittings. Mounting is by means of four user supplied 5/16 inch (or metric equivalent) screws installed at the four corners of the mounting pads. An appropriate mounting location must be selected to allow free flow of air around the enclosure. Once an appropriate location has been selected mark the hole positions on the mounting surface then drill the mounting holes and securely mount the enclosure. Figure 4: Mounting Hole Dimensions 4.2 AC Power and Earth Ground Connections The RAYMAPB does not include a power switch. The installer must supply a two-pole switch for 100 VAC to 240 VAC at 50/60 Hz. The current consumption of the unit is 0.6 A maximum. The switch should be clearly marked as the power shutoff for the equipment, visible, and accessible to the operator. The AC Power Requirement for the RAYMAPB is shown below. AC Power Input Requirements Nominal Continuous 100 to 240 V; 50/60 Hz, 0.6 A A clean power line such as instrument power line is essential. Avoid power lines serving noisy electrical equipment. The ideal solution is to power from a separate AC line, independent of all interference producing equipment. If this is not practical, consider using a line conditioner. If you use a line conditioner, connect per the manufacturer s instructions. RAYMAPB Rev. A 06/

14 Installation Improper installation can result in serious injury or death to personnel! The RAYMAPB was designed to meet IEC : Safety Requirements for Electrical Equipment for Measurement. The installation should be performed as directed in this manual and following any local electrical codes. Follow all local electrical codes related to installation and grounding of electrical equipment. Compliance with IEC : Safety Requirements for Electrical Equipment for Measurement requires the installation meet the following alternating current supply and earth grounding requirements. The installation should be compliant with requirements for a Category II installation. A three-wire AC supply with a third-wire earth ground or a separate earth ground wire is required. Power cables and wires should meet recognized European and American standards for Main Voltage Safety with insulation suitable for single fault condition (600V, 105 C/221 F). Cable gland and compression fittings for the power cable must comply with European and American standards as dictated by the power cable selected. The wire size for the L and N AC power connections should be no larger than 18 AWG (1 mm²). These power wires cannot be larger in diameter than the ground wire. A ground wire must be connected to the Protective Earth terminal. The ground wire must be 18 AWG or equivalent per IEC A two-pole power shutoff or safety switch should be incorporated within the main power line that powers the Raytek equipment. This switch should be in close proximity to the operator. The switch should be clearly marked as the power shutoff for the equipment. A properly sized circuit breaker is required in the AC supply lines connecting power to the Power Supply. The two-pole switch (and all circuit breakers) should comply with IEC standard. Switches and circuit breakers that carry the markings of TÜV, VDE or other European Agencies do meet the IEC standard. 12 Rev. A 06/2014 RAYMAPB

15 Installation 4.3 Connecting the AC Power and Ground Wires Use tinned stranded 18 AWG (1 mm²) or equivalent wire for all AC power and ground connections. Strip insulation from wires 1/4 inch (8 mm). To prevent personal injury, make sure the Mains disconnect switch is off before removing lid. To access the power wiring and ground terminals, carefully unscrew the four screws and clamps that secure the lid onto the enclosure. Leave the red and black wires connected to the power supply; these wires are for the 24 VDC power to the terminal strip for the sensor. Figure 5: AC Power Wiring Detail Remove the shipping hole plug from the cable port on the right side of the RAYMAPB, the right side of the enclosure is the side with only one cable port. Then install customer supplied cable gland and pass AC cable though cable gland. Next connect the LINE and NEUTRAL wires of the AC power line to the Power Supply inside the RAYMAPB box. Observe the polarity of these connections, LINE to AC (L) and NEUTRAL to AC (N), as indicated on the power supply. The Power supply module Ground connection is pre-wired at the factory. Do not remove this wire. You must provide a Protective Earth by connecting a ground wire to the threaded grounding stud on the mounting plate inside the RAYMAPB exactly as shown in the Ground Wire Detail Drawing and illustration shown in Figure 6. Disassemble the ground stud assembly; crimp the earth ground wire to Item 5. Reassemble the stud assembly exactly as shown making sure that the Protective Earth connection is installed first and makes direct contact with the mounting plate. Make sure all hardware is tightly fastened in each step of the reassembly. To prevent possible electrical shock, fire or personal injuries make sure that the RAYMAPB is grounded before use.

All signal cable shielding must be grounded to the RAYMAPB enclosure with customer supplied Grounding Cable Glands. Customer supplied grounding cable glands must also be rated for minimum IP65 ingress protection (IEC 60529) in order to maintain enclosure rating. All cables must be properly dressed for shield grounding. Twisted pair wires must remain twisted and kept as short as possible. The sensor cable is supplied with the connector attached on one end and the opposite wiring end of the cable is prepared with connector terminals for easy installation Cable Ports and Cable Glands Three cable ports are provided for routing the various signal and power cables. The ports accept 1/2 inch NPT cable glands or conduit. All cables routed to the RAYMAPB must be routed through sealed cable gland fittings or conduit. The hole plugs shipped with the RAYMAPB are for shipping purposes only, they do not provide IP65 sealing. All cable ports must have cable glands, conduit, or sealing hole plugs installed to maintain enclosure rating. 14 Rev. A 06/2014 RAYMAPB

17 Installation Customer supplied cable glands must have a cable diameter range that match the cables used. Use properly sized cable glands, do not attempt to improvise by making the cable thicker to fit cable gland. Grounding cable glands are required for the sensor cable and for sensor input/output wiring. Grounding cable glands should ground shielding cable to RAYMAPB enclosure. Follow manufactures specifications for proper installation and cable preparation for customer supplied grounding cable glands. The AC mains power cable does not need grounding cable glands. To maintain IEC compliance the Sensor, ma Output, Trigger Input, and Sensor Relay cable shields must be connected to grounding cable glands. 4.5 Sensor Interconnecting Cable Installation For safety of personnel, AC power should not be applied to the RAYMAPB when the lid is removed. Disconnect power during wiring of the unit. Remove the shipping hole plug from cable port and install customer supplied grounding cable gland following manufactures instructions. Insert the interconnecting cable into the cable gland and route all wires to their corresponding terminals identified by wire color. Insert the wires into the corresponding terminal on the terminal block and tighten. Figure 8: RAYMAPB Terminal Block RAYMAPB Rev. A 06/

18 Installation 4.6 Connecting Device Cables to RAYMAPB Recommended Cable Types To maintain signal integrity and reduce noise pick-up, twisted pair shielded cables with braid shielding should be used for connecting to all Sensor inputs and outputs. Belden low capacitance computer cable types 9829, 9830, 9831, 9832, 9839 and 9833, or equivalent cables are recommended. Each of these cables has a different number of wire pairs varying in quantity from 2 to 7 pairs. The cable selected should have a twisted pair nominal impedance of 100 Ω and nominal capacitance between conductors should not exceed 15.5 pf/ft (50.9 pf/m). All user-supplied cables should be grounded to the RAYMAPB with customer supplied grounding cable glands. Select cable glands that match the cable diameters of cable to be used. 16 Rev. A 06/2014 RAYMAPB

19 Installation Grounding and Shielding Follow all grounding and shielding instructions provided below. Proper connection of the cable shields is important to avoid noise and ground loop problems that may cause errors. The use of Grounding Cable Glands connects the cable shield to ground at the RAYMAPB. Prior to making any wiring changes ensure that AC power is off! Notes: Figure 9: RAYMAPB Wiring 1. This symbol designates a Protective Earth terminal. 2. If you use a line conditioner or isolation transformer, connect per manufacturer s instructions. Observe grounding instructions and make sure earth ground is supplied to Ground terminal. 3.
