Disconnect Switch External Handle
(Factory Mounted Option)
Units ordered with the factory mounted disconnect switch comes equipped with an externally
mounted handle. This allows the operator to disconnect power from the unit without having to
open the control panel door. The handle locations and its three positions are shown below;
“ON” - Indicates that the disconnect switch is closed, allowing the main power supply to be applied
at the unit.
“OFF” - Indicates that the disconnect switch is open, interrupting the main power supply to the unit
controls.
“OPEN COVER/RESET” - Turning the handle to this position releases the handle from the
disconnect switch, allowing the control panel door to be opened.
Once the door has been opened, it can be closed with the handle in any one of the three positions
outlined above, provided it matches the disconnect switch position. See Figure 33.
The handle can be locked in the “OFF” position. While holding the handle in the “OFF” position,
push the spring loaded thumb key, attached to the handle, into the base slot. Place the lock shackle
between the handle and the thumb key. This will prevent it from springing out of position.
