Field Installed Power Wiring
An overall dimensional layout for the field installed wiring entrance into the
unit is illustrated in Figure 4. To insure that the unit's 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 nameplate
ratings. The available supply power 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.
CAUTION
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.
Circuit Breaker External Handle
(Factory Mounted Option)
Units are provided with an externally mounted circuit breaker 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 circuit breaker is closed, allowing the main
power supply to be applied at the unit.
“OFF” - Indicates that the circuit breaker 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 circuit breaker, allowing the control panel door to be
opened.
