7-3-8. Compressor Operation Output : TCB-PCIN4UL
<Electrical Rating>
208-230 VAC, 10 mA or more, 1A or less
24 VDC, 10 mA or more, 1 A or less (non-conductive load)
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, OUTPUT2 and OUTPUT3 from left to right when facing the front
of the outdoor unit, as shown in the diagram.
Note 1: Output Relay (K1, K2, K3) Contact Specifications
• Output terminals (OUTPUT1, 2, 3) must satisfy the following electrical rating.
• When connecting a conductive load (e.g. relay coil) to loads K1, K2 and K3, 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.
