1.7 Electrical Installation

For connector overview (➜ # 213).For wiring diagrams refer to the Installation Manual.

1.7.1 Important Notes

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.
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 rotat-
ing.
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 warn-
ing 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 con-
nections.
To be sure, measure the voltage in the DC bus link and wait until it has fallen below 50 V.
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.
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 (➜ # 17). 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 off circuit of the installation. The emergency off
circuit must operate the supply contactor.

1.7.2 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.
For EMC-compliant shielding and grounding, see Installation Manual.
Ground the mounting plate, motor housing and CNC-GND of the control system.
3. Wire the drive and connectors.
Observe the "Recommendations for EMI noise reduction": see Installation Manual
Connect all interface according to the wiring diagrams in the Installation Manual.
4. Check the wiring against the wiring diagrams in the Installation Manual.
DANGER
High Voltage up to 900 V!
