Note 1: Specifications of display relay contact
• The terminal for display output ([Operation] terminal) must satisfy the following electrical rating.
<Electrical Rating>
220 to 240 VAC, 10 mA or more, 1 A or less
24 VAC, 10 mA or more, 1 A or less (non-conductive load)
When connecting a conductive load (e.g. relay coil) to the display relay load, 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.
The optional P.C. board should be connected to the header outdoor unit (U1).

6-8-2. Power peak-cut Control (Extended)

Operation
An external power peak-cut control signal limits the peak capacity of the outdoor unit.
L1: Power peak-cut control indication lamp
SW1: Power peak-cut control ON switch*1
SW2: Power peak-cut control OFF switch*1
*1 The inputs of SW1 and SW2 can be either pulse (100 msec or wider) or step signals.
* Be sure to provide a contact for each terminal.
