Before you start
- Install the safety retaining nut onto the upper-right mounting bushing to prevent Transfer Switch from falling outward which could cause personal injury or damage to the switch.
Procedure
- Open the cabinet door (lower door on 600-800-Amp switches).
- All arc chutes and pole covers must be in place; the Transfer Switch normal contacts must be closed.
- 150-400-Amp: align the Transfer Switch on the guide rods and push the transfer switch in until it stops.
- 600-800-Amp: lift the back panel onto two support brackets, press the balancing handle down until slots accept the mounting bushings, push the panel flat and secure by lifting the balancing handle.
- 600-800-Amp: install the safety retaining nut; position linkage from the Isolation Handle between the U bracket, insert the quick-disconnect pin and press ring flush.
- Reconnect the in-line disconnect plugs by grasping and pressing them together; reconnect wires previously removed from auxiliary contacts.
- Close the cabinet door. Unlock the Isolation Handle and put it in the TEST position, then the CLOSE position; put the Bypass Handle in the AUTO position.
