Turn off the power
Lock out/tag out device; Wait five minutes to discharge all voltages. Open the bay door of the power structure. Replace the isolation board 1. Use the instrument to test the voltage of AC lines, DC buses and terminals on the isolation board. 2. Wear the ESD wrist strap and connect it to the PE bus (the rear ground bar at the bottom of the unit). 3. Remove Lexan ? Isolate from the isolation plate. 4. Disconnect P1's grounding connection, J1's feedback connection, J2's ribbon cable and J7's current sensor connection (as shown in Figure 1). 5. Disconnect terminal blocks TB5 and TB6. 6. Rotate the six mounting brackets anticlockwise, release the circuit board and pull it out. 7. Remove the load resistor from each terminal block. 8. Put the isolation plate in the anti-static bag! NOTE: If any voltage is present, remove the voltage source. Check the voltage again before proceeding to the next step.
KIT-LOAD RESISTOR
TB2 is only used for B series RGU (or RGU to AC line to DC bus to main control board (J12) to unused current sensor T phase load resistor (F17, F18, F19) S phase load resistor * R phase load resistor to control circuit circuit. Current Code Voltage Code Load Resistor Kit Number Ohm% Tolerance Type J N, Current Voltage Series Code Typical RGU nameplate located near the main control panel For example, this nameplate shows current code L and voltage code C. The appropriate kit is 2364-SDP06A. Since the nameplate shows that this is a series a device, no resistor is required in TB2. A Series B Publication 2364F-5.13 June 1999 RGU ? Replace the isolation board 5 Install the isolation board 1. Fix the load resistor in the terminal on the new board (verify that the transparent insulating layer does not enter the terminal). Tighten to 6 lb in (0.7 N-m). Note: TB2 is only used for B series RGUs (see data nameplate). 2. Place the circuit board on the six brackets and fix the circuit board. 3. Connect terminal blocks TB5 and TB6 to the isolation board. The terminal block must be firmly pressed into the appropriate socket. 4. Connect the feedback connection to J1, the ribbon cable to J2, the current sensor to J7, and the PE ground wire to P1
