2.2 Residual hazards
Protection of
persons
After mains switch-off, the power terminals U, V, W and +U

,-U
DC
remain live for at least three minutes.
•
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
devices
Cyclic connection and disconnection of the controller supply voltage at L1, L2, L3 or +U
DC
,+U
DC
can overload the
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
transfer
During paramet er set t ransfer, the control t erminals of the 9300 controller can have undefined states!
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”.
