3 - CONNECTIONS
• All connection work
must be performed 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 voltages on the cables or
connections of the mains supply, the
motor, the braking resistor or the filter
may cause fatal electric shocks. Contact
must be avoided in all circumstances.
• The drive must be supplied via a
circuit-breaking device so that it can be
powered down safely.
• The drive power supply must be
protected against overloads and short-
circuits.
• The drive stop function does not
protect against high voltages on the
terminal blocks.
• The drive contains capacitors
which remain charged at a fatal voltage
even after the power supply has been
switched off. Wait 10 min after powering
down the drive before removing the
protective cover.
• Check that the voltage and
current of the drive, the motor and the
mains supply are compatible.
• To ensure that the drive
conforms to UL standards, use only
class 1 copper wires, 60/75°C.
3.1 - Access to the terminal blocks
Removing the cover:
1) Using a screwdriver, loosen the screw(s)
at the base of the drive until you can lift up
the cover.
2) Lift up the base of the cover completely.
3) Pull the cover to the side and backwards
(see diagram below).
• The cover must be replaced after
the terminal blocks have been
connected.
