Death or severe injuries when touching live terminals.
Switch off the mains voltage and wait for at least 3 minutes.
Check whether terminals are isolated from supply, since
– the power terminals U, V, W, +UG, −UG, BR1, BR2, and the pins of the FIF
interfaces still carry dangerous voltage for at least 3 minutes after
power−off.
– the power terminals L1, L2, L3; U, V, W, +UG, −UG, BR1, BR2, and the pins of
the FIF interfaces carry dangerous voltage when the motor is stopped.
– the relay outputs K11, K12, K14 can carry dangerous voltage when the
drive controller is disconnected from the mains.
The device or parts of it are destroyed.
Always switch off the voltage supply when working on the device. This must
be especially observed in the following cases:
– Before opening the housing.
– Before connecting/disconnecting connectors.
– Before plugging in / removing modules.
Before working on the device, the personnel must be free of electrostatic
charge.
Do not touch the contacts.
