Danger!
Dangerous electrical voltage
Terminals can carry dangerous electrical voltage − also if the motor is stopped or after
the mains is switched off!
Possible consequences:
ƒ Death or severe injuries when touching live terminals.
Protective measures:
Before all operations on the controller
ƒ Switch off the mains voltage and wait for at least 3 minutes.
ƒ 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.
(
Stop!
The device contains components that can be destroyed by electrostatic discharge!
Before working on the device, the personnel must ensure that they are free of
electrostatic charge by using appropriate measures.
)
Note!
An earth−leakage circuit breaker between the supplying mains and the controller can be
activated by mistake ...
ƒ by capacitive compensation currents of the cable shields during operation
(especially with long, shielded motor cables),
ƒ by simultaneous connection of several controllers to the mains supply,
ƒ if additional interference filters are used.
