GEH-706 Installation Instructions

The Distribution Cable Terminal Block is used to carry a variety of electronic signals between Spectra ® RMS Molded

Case Circuit Breakers with microEntelliGuard TM Trip Units. These breakers are interconnected via daisy-chained terminal blocks with common power, communication wiring, and voltage wiring (SDCTBA22C only).

Figures 1 and 2 show how the Distribution Cable Terminal Block is used in a typical microEntelliGuard TM system.

Connections

The screw terminals on the Distribution Cable Terminal

Block are labeled by function for clarity. The terminal strip pocket will accommodate a spade lug or ring terminal with a tongue width up to 0.320 inches. The terminal screw size is 10-32. To make the connection, attach an appropriate spade lug or ring terminal to the wire, slip the fastener beneath the terminal screw and tighten.

The Distribution Cable Terminal Block contains a cable with a 20-pin plug connector. To connect the end of the

Distribution Cable Terminal Block to a Spectra ® RMS

Molded-Case Circuit Breaker with a microEntelliGuard TM

Trip Unit, insert the breaker cable plug into the terminal block connector until the interlocks latch into the notch and hold the plug in place (See Figure 8).
