16. ELECTRICAL CONNECTIONS

Preliminary safety information
The electrical connection must be made according to the wiring diagram enclosed with the unit and in com-
pliance with local and international regulations.
Make sure the disconnector of the unit power supply line is upstream the unit. Ensure it is padlocked or that
the appropriate warning is present indicating not to operate.
Check that the power supply corresponds to the rated data of the unit (voltage, phases, frequency) shown on
the wiring diagram and on the nameplate attached to the unit.
Power supply cables must be protected upstream against electric short-circuit and overload by a suitable
device complying with current standards and laws.
The cross-section of the cables must be suitable for the calibration of the upstream protection system and
must take into account all factors that may affect it (temperature, type of insulation, length, etc.)
The warranty will be void if the power supply does not comply with the above limits.
Make all earthing connections required by current standards and legislation.
Make sure to disconnect the power supply before beginning any operation.

FROST PROTECTION:
