1512A-UM102B-EN-P – June 2013
To avoid shock hazards, lock out incoming power
(see page 5-3) before working on the 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.
1) Complete the Power Lockout Procedure (see Page 5-3).
2) Open the medium voltage door. Use the Door Interlock
Circumvention procedure described on page 5-2 to move the
isolation switch handle halfway between the OFF and ON position
(see Figure 5.8). Keep the handle in this position until the
adjustment procedure is completed.
3) With the contactor in the OFF position, insert a 0.060 in. (1.5 mm)
feeler gauge in the gap between the interlock lever and the
isolation switch operating lever. The gap must be between 0.039 in.
to 0.078 in. (1.0 mm to 2.0 mm).
4) To reduce the gap distance, follow steps 5-7.
To increase the gap distance follow steps 8-10.
