7.3 ELECTRICAL CONNECTION / EARTHING
Check that motor winding corresponds to site electric power
supply characteristics before electrical connections are performed.
Connecting a 230/400V motor on a 400V power supply or
connection of a 400/690V motor on a 690V power supply might
drive to motor destruction if terminal strip are positioned in a wrong
way.
Electrical connection should be performed by qualified personnel
only having necessary agreements and in compliance with local,
national and international regulations.
Equipments used in an ATEX zone will be connected in compliance
with CEI60079‐14. It is the responsibility of the end user to select
proper type and size of electric cable.
Respect motor manufacturer instructions to make electric motor
connection (refer to the instructions supplied with the motor. they
are usually indicated inside motor junction box). Sensors will be
connected in compliance with the instructions given in dedicated
instruction manual.
7.3.1 TERMINAL STRIP POSITIONNING FOR STAR
(Y) AND DELTA () CONNECTION (MULTI‐
VOLTAGES ELECTRIC MOTORS)
Multi‐voltage winding for voltages 230/400V and 400/690V :
6 wiring terminals :
To change motor direction of rotation reverse two phases on wiring
terminals. Connection of earthing terminal is mandatory.
7.3.2 LOWER VOLTAGE :  CONNECTION
Voltage : U
7.3.3 HIGHER VOLTAGE : Y CONNECTION
Voltage : U3
