9.1 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.
DANGER
High Voltage up to 900 V
There is a danger of serious personal injury or death by electrical shock
or electrical arcing. Contacts can still have dangerous voltage present up
to 7 minutes after switching off mains voltage.
Control and power connections can still be live, even if the motor is not
rotating. The built-in LED does
not
indicate the real voltage level.
Only install and wire the equipment when it is not live, that is, when
neither the electrical supply nor the 24 V auxiliary voltage nor the sup-
ply voltages of any other connected equipment is switched on.
Make sure that the cabinet is safely disconnected (for instance, with a
lock-out and warning signs).
Never remove electrical connections to the AKD-N while it is live.
Wait at least 7 minutes after disconnecting the AKD-C from all power
supply sources before touching potentially live sections of the equip-
ment (e.g. contacts) or undoing any connections.
Always measure the voltage in the DC bus link at connector X14 on
AKD-C and wait until the voltage is below 50 V before handling com-
ponents.
Since the leakage current to PE is more than 3.5 mA, in compliance with IEC 61800-5-1 the
PE connection must either be doubled or a connecting cable with a cross-section >10 mm²
must be used. There is a danger of electrical shock with possible personal injury. Deviating
measures according to regional standards might be possible.
Wrong DC Bus link 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 diagrams: (
It is permissible to use the setup software to alter the settings of the drive. Any other alter-
ations will invalidate the warranty.
