WARNING
All wiring must be performed by an authorized
electrician.
All components procured on the side and all elecrtic
construction shall comply with the applicable
legislation.
DANGER: HIGH VOLTAGE
To avoid electrical shock, make sure to disconnect the
power supply 1 minute or more before servicing the
electrical parts. Even after 1 minute, always measure
the voltage at the terminals of main circuit capacitors
or electrical parts and, before touching , make sure that
those voltages are 50VDC or less.
NOTICE
To persons in charge of electrical wiring work:
Do not oerate the unit until the refrigerant piping is
complete. (Running it before the piping is ready will
break the compressor.)

Precautions on electrical wiring work

When servicing the unit requires the refrigerant system
to be opened, treatment and evacuation of refrigerant
must be done in accordance with applicable legislation.
Refrigerant can not be charged until field wiring has been
completed.
Refrigerant may only be charged after performing the
leak test and vacuum drying.
DANGER
Before obtaining access to terminal devices, all
supply circuits must be interrupted.
Be sure to install an earth leakage circuit breaker
in accordance with aplicable legislation. Failure to
do so may cause electrical shock.
