In the grid-connected mode, between the appliance and the grid an omnipolar switch must
be inserted, having a 3 mm minimum opening between contacts, suitable to the load used
and in accordance with the regulations in force.
The yellow/green earth cable must not
be interrupted by the switch.
Connection of power cable
Mod. CV5P – CV2R
-
The terminal board is on the rear panel of the appliance. Open the
terminal board cover by obtaining leverage with a screwdriver on the two side fins. Loosen
the cable gripper screw and allow the cable to pass through it. Arrange the conductors so
that the earth conductor is the last to detach from its terminal if the cable goes into a state of
faulty traction.
Connect the phase conductor to the terminal marked with the letter "L", the neutral
conductor to the terminal marked with the letter "N" and the earth conductor to the terminal
marked with the symbol
. Tighten the ring-nut of the cable gripper and close the terminal
board cover. The appliance must be connected to an equipotential system whose efficiency
must first be checked according to current legal regulations. This connection must be made
between different appliances by using the appropriate terminal marked with the symbol .
The equipotential conductor must have a minimum diameter of 10 mm
2
The equipotential
terminal is at the rear of the appliance. When the appliance is operating, the supplied voltage
must not deviate from the nominal voltage value of ±10%.
Mod. CV5P5 – CV5E-90 A – CM5E-90 A
- For access to the terminal board, remove the
rear panel of the appliance. Loosen the cable gripper and allow the cable to pass through.
Locate the conductors so that the earth cable is the last to detach from its terminal in the
event of reverse pulling. Connect the phase conductors on the terminals marked “L1” and
“L2”, the neutral conductor to the terminal marked “N”, and the earth conductor to the
terminal marked with symbol
according to the following lay-out:
380 - 400V~ 2N

(this electrical connection lay-out is also available near the power supply terminal board).
Tighten the cable gripper and re-fit the rear panel of the appliance. The appliance must be
connected to an unipotential system whose efficiency must be suitably verified according to
current legal regulations.
This connection must be made between different appliances using the terminal marked
with the symbol
. The unipotential conductor must have minimum diameter of 10 mm

. The
unipotential terminal is located low down at the rear of the appliance.
The power cable must comply with the following characteristics:
