Removing the Remote Close

Use the following procedure to remove the Remote Close

solenoid and circuit board for replacement, as illustrated

in Figure 55. If only the solenoid or circuit board is to be

replaced, it is not necessary to remove both components.

1. Carefully place the breaker on a suitable working

surface, resting on the primary disconnects, so that

the bottom of the breaker is accessible.

2. Disconnect the two Remote Close wires at terminals

9 and 18 of the secondary disconnect. Cut the wire

ties, as needed, so that the wires can be removed

with the Remote Close.

3. Remove the two screws, lock washers, and flat wash-

ers connecting the Remote Close module to the

breaker frame.

4. Remove the snap ring connecting the Remote Close

actuator to the pin on the charging mechanism and

remove the module.

5. The Remote Close solenoid or circuit board can

now be separately replaced on the module.

Installing the Remote Close

Use the following procedure to install the replacement

Remote Close, as illustrated in Figure 55. If this is a new

installation into a breaker that was not equipped at the

factory with a Remote Close, see the installation

instructions in DEH172, supplied with the Remote Close

kit. (The circuit breaker should be resting on the

secondary disconnects with the right pole opening spring

removed, as in the removal procedure above.)

1. Insert the connecting pin on the breaker closing

mechanism through the hole in the end of the

Remote Close actuator and secure with the snap

ring.

2. Line up the mounting holes in the Remote Close

module with the two tapped holes in the bottom of

the breaker frame. Insert a screw with lock washer

and flat washer into each hole and tighten.

3. Run the wires from the Remote Close module to the

secondary disconnect and connect the wires to

terminals 9 and 18. Attach the wires to the breaker

frame with wire ties as needed.
