Installing circuit breakers in a 12 CB Module on the DIN rail

Install the C60 style Merlin Gerin Circuit Breaker to the mounting DIN Rail on the 0M-2188 or 0M-2189 module with the DIN rail lock positioned toward the bus finger. Open the bus connection by loosening the bus side tightening screw. Open the DIN rail lock. Slide the CB unto the bus finger until the front edge of the CB clears the edge of the DIN rail. Lower the front edge of the CB onto the DIN rail and slide the CB back until the edge of the DIN rail fully enters the CB rail slot #1. Lower the rear of the CB onto the DIN rail. Slide the CB forward slightly to seat rail slot #2. Engage the CB DIN rail lock. Tighten the CB connection screw on the bus finger.

Installing circuit breaker wiring (both types of circuit breaker modules)

Insert the load wire and the flat spade of the alarm cable into the open load side of the CB. Tighten the CB load side tightening screw. Route the alarm cable to the alarm PWB (trim the wire length as required and strip the end of the wire approximately ¼ inch (6mm). Insert a small bladed screwdriver into the small opening above the desired position and then insert the stripped alarm that has been cut to length. Remove the screwdriver to capture the alarm lead. Label the circuit breaker as desired using the label kit provided with the module. Dress the load wire and the alarm cable as required to the lead support bracket.
