Fig. 57 – Detail of electrical connection for any other unit module
Refer to the specific wiring diagram for the unit purchased. The wiring diagram may not be on the unit or it could be lost, in that case
please contact your manufacturer representative, who will send you a copy.
In case of discrepancy between wiring diagram and electrical panel/cables, please contact the manufacturer representative.
This unit includes non-linear loads such as inverters, which have a natural current leakage to earth. If an Earth Leakage Detector is
installed upstream the unit, a type B device with a minimum threshold of 300 mA must be used.
Electrical equipment can operate correctly in the intended ambient air temperature. For very hot environments and for cold
environments, additional measures are recommended (contact the manufacturer representative).
The electrical equipment can operate correctly when the relative humidity does not exceed 50 % at a maximum temperature of +40
°C. Higher relative humidities are permitted at lower temperatures (for example 90% at 20 °C).
Harmful effects of occasional condensation shall be avoided by design of the equipment or, where necessary, by additional measures
(contact the manufacturer representative).
This product complies with EMC standards for industrial environments. Therefore, it is not intended for use in residential areas, e.g.
installations where the product is connected to a low voltage public distribution system. This product needs to be connected to a low
voltage public distribution system, specific additional measures will have to be taken to avoid interference with other sensitive
equipment.
The units must be connected to a TN power supply system.
If the units need to be connected to a different type of power system, for example the IT system, please contact the factory.
All the electrical connections to the unit must be carried out in compliance with national laws and european
directive and regulations in force.
The connections to the terminals must be made with copper terminals and cables, otherwise overheating or
corrosion may occur at the connection points with the risk of damaging the unit. The electrical connection must
be carried out by qualified personnel, in compliance with the laws in force. There is a risk of electric shock.
Failure to disconnect power before servicing could result in death or serious injury.
Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/ tagout
procedures to ensure the power can not be inadvertently energized. Verify that no power is present with a
voltmeter.
Before any installation and connection works, the unit must be switched off and secured. Since this unit includes
inverters, the intermediate circuit of the capacitors remains charged with high voltage for a short period of time
after being switched off.
Do not operate to the unit before 20 minutes after the unit has been switched off.
