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
).

4. Bolt the cabinet door closed so the pins on the dead bolt counterpart
make contact with the deadbolt assembly. Doing so should leave two
marks of torque sealant or grease on the assembly where the pins made
contact (see Figure 18 on page 26
).
5. Slightly loosen the adjustment bolts on the counterpart and make the
necessary movements on the counterpart to ensure that the pins align
with the landing plates on the deadbolt assembly. As the amount of
counterpart movement required is an estimate, it can take a couple
attempts to properly align the assembly.
6. Clean the torque seal/grease from the key interlock once finished
aligning the counterpart.
Once properly aligned, the key should turn freely when the cabinet door is fully
bolted shut. If the key does not function when the door is tightly bolted closed,
adjustments will have to be made to the depth of the counterpart. This can be
done by adding shims on the landing plate where the counterpart is mounted.
