AKD Installation | 3 Safety
Earthing!
It is vital that you ensure that the drive is safely earthed to the PE (protective earth) busbar in
the switch cabinet. Risk of electric shock. Without low-resistance earthing no personal pro-
tection can be guaranteed.
High voltages!
The equipment produces high electric voltages up to 900V. Do not open or touch the equip-
ment during operation. Keep all covers and cabinet doors closed.
During operation, drives may have uncovered live sections, according to their level of enclo-
sure protection. Wait at least seven minutes after disconnecting the drive from the main
supply power before touching potentially live sections of the equipment (such as contacts) or
removing any connections.
Capacitors can have dangerous voltages present up to seven minutes after switching off the
supply power. Always measure the voltage in the DC bus link and wait until the voltage is
below 40 V before handling components.
Never undo any electrical connections to the drive while it is live. There is a danger of elec-
trical arcing with damage to contacts and personal injury.
Never modify the drive!
It is not allowed to modify the drive without permission by the manufacturer. Opening the
housing causes loss of warranty.
