Danger!
The controller is a source of danger which may cause death or serious personal
injury or property damage.
To avoid these dangers, observe the general safety and application notes in the
Mounting Instructions before switching on the controller!
Furthermore, observe the following notes for commissioning!
Protection of persons
Before working on the controller, make sure that no voltage is applied to the power
terminals since
– the power terminals U, V, W, +UG, -UG, Rb1 and Rb2 remain live for 3 ... 20 minutes
after the mains has been disconnected.
– the power terminals L1, L2, L3; U, V, W, +UG, -UG, Rb1 and Rb2 remain live with the
motor stopped.
Device protection
Plug on/remove all pluggable terminals only in deenergised state!
Cyclic connection/disconnection of the mains voltage can overload and destroy the
input current limitation of the controller:
– Cyclic mains switching of 5 times in 5 minutes is permissible without restrictions.
Observe the tightening torque defined in the documentation for the electrical screw
connections so that they cannot loosen during operation (due to temperature
influence or mechanical load).
