(1) Reverse Phase Protector
• The Reverse Phase Protector is operated at
nominal voltage of 440 VAC to 480 VAC.
The reverse phase protector is mounted on a
plug-in socket terminal block where it can
easily be plugged-in or removed during
service.
• The internal relay of a reverse phase protector
is energized and LED is on when the phase
sequence is correct. If the phases are reverse,
the out put relay will not energize.
• The reverse phase protector is reset
automatically upon correction of the fault.
Specifications:
- Rated Line Voltage: 440/480 V
- Rated Output: 8 A resistive at 240 V
- Mounting: Plug-in socket (8 pin, octal plug)
(2) Capacitors
• The capacitors are used to temporarily boost the power output available to the fan motor at
start-up.
• The specifications of each capacitor are listed below:
Capacitor Application Voltage Rating Capacitance
Evaporator Fan Motor 440 VAC 15 µF
Condenser Fan Motor 370 VAC 25 µF
