6.3 Wiring diagram
6.3.1 Electrical connection
The trolley must be connected via the plug supplied to the power supply, checking:
- the laws and technical specifications valid in the place and at the time of installation
- that the power supply voltage and the frequency at the connection point are compatible with those indicated on the rating plate
of the mobile filtration unit
- the data shown on the rating plate.
It is recommended to use a multi-wire cable with a minimum cross-section of 4 x 2,5 mm
2
for the econnection of the electric motor.
The red plug indicates a three-phase motor, the blue plug a single-phase motor.
The supply voltage must correspond to the voltage specified on the rating plate.
The construction features of the electric cable guarantee great flexibility, excellent resistance to weather conditions, oils and greases,
mechanical and thermal stresses: Standard IMQ-CPT-007, CEI EN 50525-2-2.
Compliant with requirements of the BT 2006/95/CE directives.
The terminal box contains metal elements that are under hazardous voltage;
after making the connections, always close the box cover.
NOTE
!
6.3.3 Electrical connection of a single-phase motor - not applicable for UFM181
6.3.2 Triangular electrical connection of a three-phase motor
This motor is connected to the three-phase line, which can be 230V or more commonly 400V.
Since the windings that make up the motor must be powered at 230V, the connection must be
made in the following manner:
- Delta connection: this connection applies the same voltage to the windings as to the line.
To be able to change the direction of rotation it is sufficient to invert two phases by acting
directly on the appropriate five-pole CE plug (see photo on the right).
