6-6-3-1. Power peak-cut Control (Standard)
(1) Four-core cable support
Operation
The demand request signal from the outside restricts the maximum capability (or maximum electric power) of
an outdoor unit.
L1: Power peak-cut control indication lamp SW1: Power peak-cut control ON switch (ON as long as target
power peak-cut control has been reached or exceeded, normally OFF)*1
SW2: Power peak-cut control OFF switch (OFF as long as target power peak-cut control has not been reached
or exceeded, normally ON)*1
*1 The inputs of SW1 and SW2 can be either pulse (100 msec or longer) or step signals.
Do not turn on SW1 and SW2 simultaneously.
* Be sure to provide a contact for each terminal.

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.
Note 2 : COM contact specifications
• COM terminals have DC12 V output with a basic insulation. Use a
switch, such as a relay or photocoupler, insulated from a
controller (locally procured) for CO (Change-Over) contact or NO
(normally-open) contact.
• DC12 V has a current-limiting resistor of 3.3
:
.
• For non-voltage contacts, use a relay with minimum applicable
load of DC12V,3mA or less.
