Important Notes
Note: Only professional staff who are qualified in electrical engineering are allowed to install the
drive. Wires with color green with one or more yellow stripes must not be used other than for
protective earth (PE) wiring.
WARNING
High Voltage up to 900 V!
There is a danger of serious personal injury or death by electrical shock or electrical arcing.
Capacitors can still have dangerous voltages present up to 7 minutes after switching off the supply
power. Control and power connections can still be live, even if the motor is not rotating.
Only install and wire the equipment when it is not live.
Make sure that the cabinet is safely disconnected (for instance, with a lock-out and warning signs).
Never remove electrical connections to the drive while it is live.
Wait at least 7 minutes after disconnecting the drive from the main supply power before touching
potentially live sections of the equipment (e.g. contacts) or undoing any connections.
To be sure, measure the voltage in the DC bus link and wait until it has fallen below 50 V.
Note: Wrong mains voltage, unsuitable motor or wrong wiring will damage the drive. Check the
combination of drive and motor. Compare the rated voltage and current of the units. Implement
the wiring according to the connection diagram : (
# 83) and following.
Make sure that the maximum permissible rated voltage at the terminals L1, L2, L3 or +DC,
–
DC is
not exceeded by more than 10% even in the most unfavorable circumstances (see IEC 60204-1).
Note: Excessively high external fusing will endanger cables and devices. The fusing of the AC supply
input and 24 V supply must be installed by the user, best values (
# 39). Hints for use of Residual-
current circuit breakers (RCD) (
Note: Since the leakage current to PE is more than 3.5 mA, in compliance with IEC61800-5-1 the PE
connection must either be doubled or a connecting cable with a cross-section >10 mm² must be
used. Deviating measures according to regional standards might be possible.
Note: The drive status must be monitored by the PLC to acknowledge critical situations. Wire the
FAULT contact in series into the emergency off circuit of the installation. The emergency off circuit
must operate the supply contactor.
Note: It is permissible to use the setup software to alter the settings of the drive. Any other
alterations will invalidate the warranty.
