MANAGEMENT
4.1
Storage
-
The panel is supplied in its original pack in which it must remain until the time of installation.
-
The panel must be stored in a dry covered place, far from sources of heat and with possible constant air
humidity, free from vibrations and dust.
-
It must be perfectly closed and isolated from the outside environment, so as to avoid the entry of insects,
humidity and dust which could damage the electrical components, jeopardising their regular operation.
4.2
Transport
Avoid subjecting the products to needless impacts and collisions.

INSTALLATION
Carefully follow the advice in this chapter to carry out correct electrical, hydraulic and mechanical installation.
Before attempting any installation work, make sure that power to the motor and inverter is switched off.
Strictly respect the electric supply values indicated on the electrical data plate.
5.1
Electrical connection
Attention: always respect the safety regulations!
In the power mains there must be a device that ensures complete disconnection in overvoltage
category III conditions.
Make sure that the mains voltage is the same as that on the motor data plate.
Observe the following terminals for connecting the power supply cables:
L1 - L2 - N -
⏚
"
for three-phase systems
L1 - N -
⏚
"
for single-phase systems
à
isolating switch QS1
(terminals 2T1-4T2-6T3)
Ensure that all the terminals are fully tightened, paying particular attention to the earth screw.
Refer to the Safety Booklet before making electrical connections.
5.2
Instrumental checks to be carried out by the installer
-
Continuity of the protection leads and of the main and supplementary equipotential circuits.
-
Insulating resistance of the electric system between the active circuits L1-L2-N (short-circuited with each
other) and the equipotential protection circuit.
-
Testing the efficiency of the differential protection.
-
Testing the voltage applied between the active circuits L1-L2-N (short-circuited with each other) and the
equipotential protection circuit.
-
Testing operation.
