3 - CONNECTIONS

• All connections work must be performed by

qualified electricians in accordance with the laws in

force in the country in which the drive is installed. This

includes earthing to ensure that no directly accessible

part of the drive can be at the mains voltage or any other

voltage which may be dangerous.

• The drive must be supplied through an approved

circuit-breaking device so that it can be powered down

safely.

• The drive power supply must be protected against

overloads and short-circuits.

• Check that the voltage and current of the drive, the

motor and the mains supply are compatible.

• The voltages on the connections of the mains supply,

the motor, the braking resistor or the filter may cause

fatal electric shocks. •

Only one permanent magnet motor can be connected to

the drive output. It is recommended to install a circuit-

breaking device between the permanent magnet motor

and the drive output to eliminate the risk of hazardous

voltage feedback when performing maintenance work.

• See also the recommendations in section 7.
