1.7 Electrical Installation
Connectors and Wiring overview see (
➜
# 57) and refer to the MKD Installation Manual .
1.7.1 Important Notes
Only professional staff who are qualified in electrical engineering are allowed to install the
drive system. Wires with color green with one or more yellow stripes must not be used other
than for protective earth (PE) wiring.
DANGER
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 5 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 5 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.
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.
Wrong DC Bus link voltage, unsuitable motor or wrong wiring will damage the system com-
ponents. Check the combination of drive and motor. Compare the rated voltage and current
of the units. Implement the wiring according to the connection diagrams: (
➜
# 57).
It is permissible to use the setup software to alter the settings of the device. Any other alter-
ations will invalidate the warranty.
1.7.2 Guide to electrical installation
For details refer to the MKD Installation Manual . Install the drive electrical system as follows:
1. Select cables accordance with the planned system topology, see (
➜
# 15).
2. Observe the maximum cable length definition (
➜
# 15).
3. Install shielding and ground the system components, see (
➜
# 61).
4. Wire the system components.
- Observe "Recommendations for EMI noise reduction": see MKD Installation Manual
- Connect all interface according to the wiring diagrams in the MKD Installation Manual .
5. Check the wiring against the wiring diagrams in the MKD Installation Manual .
For electrical installation of AKD-N to the machine, refer to the AKD-N Installation Manual .
