9.7 Connection to the mains power supply
Attention, Live Current
This equipment operates at high electrical power and voltages and must be
connected to the mains power supply by qualified personnel only. This must
be in accordance with local Electrical Standards and Regulations.
Before doing anything with the unit's electrical board, check that all moving parts are
working freely.
All of the values displayed on the specifications and characteristics plate must be
checked carefully to ensure that the unit is correctly protected and connected. The
electric diagram number corresponding to the equipment is on the ratings plate. Keep
the electric diagram available during the electrical wiring process.
The equipment must be connected to the mains network by a line protected against short
circuits and earth faults in the cables, whose cross section and sensitivity must
correspond to the equipment power and power line length.
The line can be designed with the nominal equipment power and current, whose values
appear on the ratings plates and wiring diagram.
The supply voltage (for standard equipment) is 3-phase and must be between 380V and
415V to operate at a frequency of 50Hz. For other kinds of connections contact the
manufacturer.
At the back of the electrical panel is a removable cover of dimensions 140x110mm which
can be replaced with a gland of appropriate size according to cable diameter.
The line connection must be made at the power terminals of terminal block X1 (PE-L1-
L2-L3) or directly on the terminals of the circuit breaker (depending on the model).
