1.7 Electrical Installation

Connectors and Wiring overview see (➜ # 135) 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.
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.
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: (➜ # 135).

1.7.2 Guide to electrical installation

For details refer to the MKDInstallation 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 (➜ # 139).
4. Wire the system components. Observe "Recommendations for EMI noise reduction"and
5. Check the wiring against the wiring diagrams in the Installation Manual.
6. Install the MKD-N DC-Bus link cover on the last MKD-N.
For electrical installation of AKD-N to the machine, refer to the AKD-N Installation Manual.

DANGER
High Voltage up to 900 V!
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.
Ensure the MKD-N DC-Bus link cover is installed on the last MKD-N before switching on
mains power.
connect all interface according to the wiring diagrams in the Installation Manual.
