Chapter 6 Operator Handle and Unit Interlock
Lock Units with Operating Handles in the ON/I Position
Follow this procedure to lock the operator handle in the ON/I
position.
1. Drill out the pre-located hole to 3/8 in. (9.5 mm) diameter
maximum.
2. Insert the shackle of the lock.
The following instructions assume that the handle is in the ON/I
position:
• For units with small handles, the pre-located hole is in the upper
portion of the operator handle assembly.
• For units with medium and large operator handles, the
pre-located hole is underneath the operator handle on the
handle assembly.
• For units with a horizontally mounted handle, the pre-located
hole is on the left-hand side of the handle assembly.
ATTENTION
Locking an operating handle in the ON/I position may be in
conflict with local codes and emergency shut down
requirements.
