ELECTRICAL CONNECTIONS
IMPORTANT
MAKE SURE THE UNIT IS NOT CONNECTED TO THE POWER SUPPLY BEFORE STARTING WORK ON ANY
ELECTRICAL CONNECTIONS
FUNCTIONAL CONNECTIONS
The following devices will have to be connected up before the unit can be started:
CONNECTION TO THE MAINS POWER
- Connect the trhee-phase line to the terminals indicated on the electrical panel with L1 L2 L3 of the general cut-out
switch.
- Connect the NEUTRAL conductor to terminal N of the electrical panel.
- Connect the EARTH conductor to the Pe terminal of the electrical panel.
- The installer must take particular care in sizing the wires for connection to the mains power supply, taking into
consideration the data on the unit’s technical datasheet sticker on the electrical panel door. It is also important to fit
a short circuit protection device rated suitably for the power capacity of the line. The protection device must present
appropriate breaking power in relation to the calculated short circuit current in that section of the system.

OPTIONAL CONNECTIONS
CONNECTING AN ANOMALY SIGNAL DEVICE
Referring to the electrical diagram, the summation shut-down signalling line can be equipped with an audible or visual
alarm device to signal anomalies detected on the unit.
The signalling device should be powered at low voltage (24V, 300mA) as per the wiring diagram.
CONNECTION TO REMOTE CONTROL PANEL
The remote control module is a faithful reproduction of the keypad on the ENERGY LIGHT control module and allows all
the operations on the machine to be performed from a remote location.
