ABB Distribution Protection Unit 1500R
Rear Terminal Block Connections
Apply only rated control voltage marked on the front panel of the unit to the positive terminal and the negative
terminal. Wire the ground stud on the rear of the case to the equipment ground bus with at least #10 gauge wire.
Figure 9-3 shows the rear terminal block layout and numbers.
With exception of the CTs and burden board, you can totally withdraw the DPU1500R from its case.
Use input IN6 as a Trip Coil Monitor (TCM) input. When the breaker is closed, a small trace current of 6 milliamperes
is passed from the positive terminal through the negative terminal and the trip coil circuit. If an open circuit is
detected while the breaker is closed, the Trip Circuit Failure Alarm (TCFA) contacts are actuated and a "Trip Coil
Failed" message appears on the MMI display.
