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 (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 wider) or step signals.
Do not turn on SW1 and SW2 simultaneously.
* Be sure to provide a contact for each terminal.

Two-core cable support
SMMS-i models allows ON/OFF power peak-cut control to be implemented using a power peak-cut control ON
input (SW1) alone, provided that the J16 jumper wire on the interface P.C. board of the header outdoor unit has
been removed.
