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.
WARNING
Hazardous Voltage!
Disconnect all electric power, including remote disconnects before servicing. Follow proper
lockout/tagout procedures to ensure the power can not be inadvertently energized. Failure to
disconnect power before servicing could result in death or serious injury.
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.
An overall layout of the field required power wiring is illustrated in Figure 18. To insure that the unit
supply power wiring is properly sized and installed, follow the guidelines outlined below.
Note: All field installed wiring must conform to NEC guidelines as well as State and Local codes.
Verify that the power supply available is compatible with the unit's name plate ratings for all
components. The available power supply must be within 10% of the rated voltage stamped on the
nameplate. Use only copper conductors to connect the 3-phase power supply to the unit.
NOTICE:
Use Copper Conductors Only!
Unit terminals are not designed to accept other types of conductors. Failure to use copper
conductors may result in equipment damage.
