As indicated on the electrical diagram of equipment (Part #1327290), it is suggested to use 2.5 mm2 section cable. The
maximum thermal protection mounted on equipment can be 4 A.
NOTE:
During the connection of field devices use the internal ducts to maintain tidy cabling.
All connections must be made by qualified staff in compliance relevant regulations. Only performing wiring
operation when power is completely removed from the unit.
Be careful that:
-
The wires are not shorted;
-
Have adequate insulation;
-
Intact until their entry into the terminal and properly locked.
ATTENTION: The Framework is connected to power supply 400V~. For other voltages indicated in paragraph
11. par. 11 you must reconnect the primary transformer ring to the desired value.
Failure to do this may result in damage to the unit.
