To align the deadbolt key interlock with its counterpart, follow these steps.
Figure 18 - Deadbolt Assembly Mounted to Door
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. If that is unavailable, almost
any grease will do (Figure 19
).
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 can exist in
the cabinet even with the circuit breaker in the off position. We recommend
that you disconnect or lock out control equipment from power sources, and
confirm discharge of stored energy in capacitors. If you must work in the
vicinity of energized equipment, the safety-related work practices of NFPA
70E, Standard for Electrical Safety in the Workplace, must be followed.
