Electrical Wiring
Power should be supplied at the voltage and frequency applicable for
each SQ version. (Standard models: 100 V AC, at 50 Hz or 60 Hz,
Oceania models: 240 V AC at 50 Hz). Use of a power supply outside the
above specification range may cause fires or electric shock.
CAUTION
1. Make sure to carry out electrical connections in accordance with JIS or
applicable standards etc.
(The actual control panel arrangement may differ from the
arrangement shown in the image on the right. The image on
the right shows the control panel for indoor specifications.)
(1) Voltage/frequency:
Standard models: 100 V AC at 50 Hz or 60 Hz
Oceania models: 240 V AC at 50 Hz
(2) Maximum current: (when the cooling system is in
operation)
SQ2: 1.5 A
SQ4: 1.7 A
SQ6: 1.7 A
(3) Install an earth leakage circuit breaker that can automatically cut off the
circuit on the power supply side.
(4) When the breaker cannot be grounded in the control panel, make sure to
perform D class grounding (with ground resistance of 500 • or less).
(not applicable for models for the Oceania region)
(5) Do not ground to water piping, steam piping, telephone lines or lightning
rods.
Make sure the power supply is OFF before carrying out work on the
wiring or inspections involving disassembly. If such work is carried
out with the power on, there is a danger that unit may malfunction or
electric shock may occur, leading to injury or other accidents.
CAUTION
Make sure that wiring work requiring a special license is carried out
by qualified personnel. Incorrect wiring work may result in
generating heat from the wiring, with the risk of injuries, burns, fire or
damage due to electrical leaks etc.
CAUTION
Do not allow any cables or wires to come into contact with the steam
piping. Steam heat will sever wiring, which may result in injury, burns,
fire, damage, etc. caused by electric shock from the wiring.
CAUTION
