The electrical connections must be performed in a workmanlike manner by
skilled personnel, respecting the regulations in effect in the country of instal-
lation. To make the necessary connections, refer to the electrical wiring
diagram in this manual.
Respect the following (not exhaustive) instructions to ensure a proper elec-
trical installation:
• During installation and maintenance make sure that power to the electric
lines has been turned off.
• Employ cables characterized by minimum cross-sections, rated voltages
and installation type adequate to the characteristics indicated in paragraph
ELECTRICAL SPECIFICATIONS and the installation environment.
•All motors are equipped with a ground terminal to connect to the ground
line of the electrical network
• Always close the cover of the terminals trip box before turning on the
electric power, after checking the integrity of the gasket seals.
The unit is not equipped with circuit breakers. It is therefore recom-
mended to install a 30-mA residual current operated circuit breaker on
the plug. Protection: minimum 10 Amp.
