Checklist
You read the complete installation and operation instructions, as described in the installer
and user reference guide.
Installation
Check that the unit is properly installed, to avoid abnormal noises and vibrations when
starting up the unit.
Power supply voltage
Check the power supply voltage on the local supply panel. The voltage MUST correspond to
the voltage on the nameplate of the unit.
Earth wiring
Be sure that the earth wires have been connected properly and that the earth terminals are
tightened.
Insulation test of the main power circuit
Using a megatester for 500 V, check that the insulation resistance of 2 MΩ or more is
attained by applying a voltage of 500 V DC between power terminals and earth. NEVER use
the megatester for the transmission wiring.
Internal wiring
Visually check the electrical component box and the inside of the unit for loose connections
or damaged electrical components.
