Opening the Unit Door in the ON/I Position
When the unit door is closed and the large rotary-operator handle is in the ON/I
position, a defeater mechanism must be deliberately operated to open the unit
door (for example, to open the door of an energized unit).
Follow these procedures to open a door
with the large rotary-operator handle in
the ON/I position.
1. Release the door latches.
2. Locate the defeater mechanism on
the right side of the handle.
3. Use a flat blade screwdriver to
push the defeater mechanism in
the direction of the arrow.
4. Carefully open the unit door.
ATTENTION: Follow local codes and guidelines, and the requirements of EN
50110 when working on energized equipment.
