Connecting the plate to the electrical system
Note!
The plate can be connected to the mains only by a qualified certified installer. Wilful
adaptations or modifications to the electric system are prohibited.
Guidelines for the installer
The plate is factory-set for three-phase alternating current power supply (400 V 3N~50 Hz).
It may be adapted for one-phase current power supply (230 V) by adequate bridging on the
connection strip, in accordance with the attached wiring diagram. The wiring diagram is also
provided in the bottom part of the lower cover. The connection strip can be accessed once
the lid on the bottom cover is removed. Please remember to match the mains connection
cable to the type of connection and the rated power of the plate.
Note!
Do not forget to connect the protective circuit to a clamp of the connection strip marked
with sign. The plate power supply system should be protected by appropriately
selected safety device or after the power supply protection, by appropriate safety
switch cutting off the power in case of emergency.
