2.3 Residual hazards
Operator’s safety After mains disconnection, the power terminals U, V, W and + U
G
, -U
G
remain live for at least 3 minutes.
- Before working on the controller, check that no voltage is applied to the power terminals.
Protection of devices Cyclic connection and disconnection of the controller supply voltage at L1, L2, L3 or + U
G
, + U
G
may
overload the internal input current limit.
- Allow at least 3 minutes between disconnection and reconnection.
Overspeeds Drive systems can reach dangerous overspeeds (e.g. setting high field frequencies for motors and
machines which are not suitable):
- The controllers do not offer any protection against these operating conditions. Use additional
components for this.
