Operation
When a compressor is in operation, a relay connected to the output terminal assigned to it is turned on (closed).
When it is at rest, the relay is turned off (open).
The output terminals are named OUTPUT1
and
OUTPUT2 from left to right when facing the front of the outdoor
unit, as shown in the diagram.
Note 1: Output Relay (K1, K2) Contact Specifications
• Output terminals (OUTPUT1, 2) must satisfy the following electrical rating.
•
When connecting a conductive load (e.g. relay coil) to loads K1
and
K2 insert a surge killer CR (for an AC
power supply) or a diode for preventing back electromotive force (for a DC power supply) on the bypass circuit.
