Disconnect Switch External
Handle (Factory Mounted
Option)
Units ordered with the factory mounted disconnect
switch come 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 location 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 at the unit.
• 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. 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.
