Isolation Blade Switch
Adjustment
The Bulletin 1500 (Series R) Isolation Switch has been updated to improve
performance. This procedure ensures the isolation switch linkage assembly
operates correctly with the new design change.
1. Insert a screwdriver in the Isolation Switch Defeater, push down and hold
at the bottom position.
2. Actuate the Isolation Switch Operating Handle from Open (black) to
Closed (red) in a continuous movement.
Do not use excessive force or speed in closing the switch. This will cause an
incorrect test result.

ATTENTION: Complete the Power Lockout procedure of the main power bus
before servicing equipment. Verify with a hot stick or appropriate voltage
measuring device that all circuits are voltage free. Failure to do so may result in
severe burns, injury, or death.
WARNING: Use suitable personal protective equipment (PPE) per local codes or
regulations. Failure to do so may result in severe burns, injury, or death.
