Field Power Wiring
Wiring must comply with all applicable codes and ordinances.
The warranty is voided if wiring is not in accordance with these
specifications. An open fuse, tripped circuit breaker, or Manual
Motor Protector (MMP) indicates a short, ground, or overload.
Before replacing a fuse, circuit breaker, MMP, or restarting a
compressor or fan motor, identify the trouble and correct.
According to the
means shall be located within sight of and readily accessible
from the air conditioning equipment. The unit can be ordered
with an optional factory mounted disconnect switch. This switch
is not fused. Power leads must be over-current protected at
the point of distribution. The maximum allowable overcurrent
protection (MROPD) appears on the unit nameplate.
All RPS, RFS, and RDT Units
DANGER
Hazardous voltage. Can cause severe injury or death.
Disconnect electric power before servicing equipment. More
than one disconnect may be required to de-energize the unit.
CAUTION
Wires are located in base rail. Move wires before drilling hole
through base rail.
All units are provided with internal power wiring for single or
dual point power connection. The power block or an optional
disconnect switch is located within the main control panel. Field
power leads are brought into the unit through 3ʺ knockouts
in the bottom of the main control panel. Refer to the unit
nameplate to determine the number of power connections. See
If the unit has a factory mounted disconnect switch, generally
the switch must be turned off to open the main control panel
door. However, the door can be opened without disconnecting
power by following the procedure covered by the
the-door Disconnect on page 142
. If this is done, use caution
since power is not removed from the unit or the controller.
NOTE:
To wire entry points, refer to certified drawings for
dimensions.
The preferred entrance for power cables is through the bottom
knockouts provided on the unit. If side entrance is the only
option, a drilling location is provided.
The drilling dimensions must be followed exactly to prevent
damage to the control panel. The dimensions provided are the
only possible point of side entrance for the power cables.
