Instructions for Changing Handle Position
Right to Left Side of Tank
It assumed that this conversion would be performed prior to the unit being placed into service in
the field in a de-energized state. Should this change be required for a unit installed with live
voltage, please take necessary precautions when working around open bus work. Please read
instructions completely before beginning handle reversal.
1. Move the Handle to the OPEN position and withdraw and remove the breaker element to
allow access to the interior of the unit.
2. Move the Handle back to the AUTO position after the breaker is removed to facilitate
removal of the handle.
3. Discharge the handle return spring using a
screwdriver as shown.
CAUTION
The spring is under compression and has
considerable stored energy. Use caution when
removing from the assembly.
4. Apply pressure to hold the handle in place and
remove both handle setscrews.
5. Remove position-indicating plate by applying
pressure underneath to handle nameplate to
dislodge the drive screws. New drive screws will
be provided in the handle conversion kit in the
hardwire bag.
