10. Electrical wiring work
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.)
10.1. 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
factory oil
charging
supply circuits must be interrupted.
C(cc)
„ Be sure to install an earth leakage circuit breaker in
accordance with aplicable legislation. Failure to do
800
so may cause electrical shock.

„ Use only copperwires.
„ A main switch or other means for disconnection,
1250
having a contact separation in all poles, must be
150
incorporated in the fixed wiring in accordance with
applicable legislation. Do not turn on the main switch
until all the wiring is completed.
„ Make sure to connect power supply cables in normal
phase.
„ Never squeeze bundled cables into a unit.
„ Fix cables so that cables do not make contact with
the pipes (especially on high pressure side).
