1.
Lock out and isolate the drive from medium voltage. Verify with a hot
stick that there is no medium voltage present.
2.
Determine that the key interlock is correctly aligned by securely bolting
the medium voltage doors of the cabinet closed and removing the key from
the lock. The key should turn easily; if any force is required to turn the key,
the deadbolt alignment requires adjustment.
3.
Open the doors of the cabinet and inspect the key assembly. Place high
visibility grease on the pins of the deadbolt counterpart. The factory
recommends using yellow torque sealant, however if it is unavailable
almost any grease will do (
).
ATTENTION: Servicing energized industrial control equipment can be
hazardous. Severe injury or death can result from electrical shock, burn, or
unintended actuation of control equipment. Hazardous voltages may exist in
the cabinet even with the circuit breaker in the off position. Recommended
practice is to disconnect or lock out control equipment from power sources, and
confirm discharge of stored energy in capacitors. If it is necessary to work in the
vicinity of energized equipment, the safety related work practices of NFPA 70E,
Electrical Safety requirements for Employee Work places, must be followed.
