ation Manual.

1.6.1 Important Notes

DANGER
Never remove electrical connections to the drive while it is live. There is a
danger of electrical arcing with damage to contacts and serious personal
injury. Wait at least seven minutes after disconnecting the drive from the
main supply power before touching potentially live sections of the equip-
ment (e.g. contacts) or undoing any connections.
Capacitors can still have dangerous voltages present up to 7 minutes after
switching off the supply power. To be sure, measure the voltage in the DC
bus link and wait until it has fallen below 50 V.
Control and power connections can still be live, even if the motor is not
rotating.
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. Imple-
ment the wiring according to the connection diagram in the Installation Manual.
Excessively high external fusing will endanger cables and devices. The fusing of the AC sup-
ply input and 24 V supply must be installed by the user, best values (➜ # 16). Hints for use of
residual-current circuit breakers (RCD) see Installation Manual.
The drive status must be monitored by the PLC to acknowledge critical situations. Wire the
FAULT contact in series into the emergency stop circuit of the installation. The emergency
stop circuit must operate the supply contactor.
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.
It is permissible to use the setup software to alter the settings of the drive. Any other alter-
ations will invalidate the warranty.

1.6.2 Guide to electrical installation

Install the drive electrical system as follows:
1. Select cables in accordance with IEC 60204 .
2. Install shielding and ground the drive.
3. Wire the drive and connectors.
4. Check the wiring against the wiring diagrams in the Installation Manual.

For EMC-compliant shielding and grounding, see Installation Manual.
Ground the mounting plate, motor housing and CNC-GND of the control system.
Observe the "Recommendations for EMI noise reduction": see Installation Manual
Connect all interface according to the wiring diagrams in the Installation Manual.
