Installing Your RGU 7-5
8.
9. Set the trip setting of the disconnect according to manufacturer’s
instructions or per the recommended settings provided in
Appendix C of this manual. Refer to your drive system schematics
for the system’s rated current levels.
10. Verify that the circuit feeding into the isolation board (at TB5 and
TB6) is powered by 115V AC control circuitry. On the isolation
board, set SW1 to ‘115V AC Control Voltages’.
Ground-Fault Detection
If the ground-fault detection option has been selected, a meter relay
will be mounted to the door. When wired, the meter will indicate the
ground voltage, and the relay will energize when the ground voltage
exceeds the defined trip voltage.
To set up the ground-fault detection relay, connect terminals TB2-1
and TB2-2 across the power transformer grounding resistor, in
accordance with system schematics and according to transformer
manufacturer specifications (see Figure 7.2). TB1-7 and TB1-8
(normally-closed contacts) can be connected to an appropriate
monitoring device.
Note: The power transformer must have a resistive grounded-
wye secondary with a resistance of 150 ohms.
If your RGU current code is: Torque the RGU input terminals to:
