8.1 - Unit connection
Before undertaking any electrical connection, make sure
that the fan motor is suitable for electrical power supply.
All wiring must be done in accordance with applicable
electrical codes and regulations.
Earthing of unit is imperative.
The manufacturer or its representative will not be held
responsible for accidents caused by incorrect or non-existing
earthing.
The units are not supplied with electrical panel.
Wiring on the electric motors must be done at site. All
motors are designed and produced in accordance with the
standards in use.
The connection of these motors will be done according to the
indications affixed on the nameplate and on the diagram
located in the terminal box.
All motors are equipped, as standard, with a normally closed
internal overload protection sensor. This safety device shall
Caution
