Residual hazards

Protection of After mains switch-off, the power terminals U, V, W and +U
•
p persons Before working on the controller, check that no voltage is applied to the power terminals.
The discharge current to PE is > 3.5 mA. EN 50178
•
requires a fixed installation.
•
requires double PE connection or a minimum cable cross-section of 10 mm
Protection of Cyclic connection and disconnection of the controller supply voltage at L1, L2, L3 or +U
devices current input limitation:
•
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.
Parameter set
During parameter set transfer, the control terminals of the 9300 controller can have undefined states!
transfer
Therefore the plugs X5 and X6 must be removed before transfer. Thus it is ensured that the controller is inhibited and all
control terminals have the defined state "LOW".
