GEH-702 Users Manual
The microEntelliGuard TM Trip Unit communicates
directly with the Modbus. To update the wiring for use
with microEntelliGuard
TM Trip Unit, Belden 9841 cable
should be used. The COMM+ (Com TX) signal from the
distribution junction box should be connected to the
Modbus+ connection of the Modbus. The COMM- (Com
RX) signal from the distribution junction box should
be connected to the Modbus-. The shield from the
distribution junction box should be connected to the
Modbus shield. Figure 22 shows the modified wiring.
The Modbus standard requires that communication
wiring be connected using a daisy chain method with
termination resistors applied to the last slave unit in
the chain. If there is only one breaker or device using
the Modbus concentrator, the concentrator can be
removed from the system.
Once the circuit breaker is replaced in the system, some
reprogramming may be necessary. Users Manual
