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

Protection of
devices
Cyclic connection and disconnection of the controller supply voltage at L1, L2, L3 or +U

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 paramete r set transfer, the control terminals 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”.
1.4 L ayout of the safety information
All safety information given in these Operating Instructions have the same layout:
Signal word (characterises the severity of danger)
Note (describes the danger and gives information how to avoid it)
Icons used Signal words
Warning of danger
to persons
Warning of hazardous
electrical voltage
Danger! Warns of impending danger.
Consequences if disregarded:
Death or most severe injuries
Warning of a general
danger
Warning! Warns of potential, v ery hazardous situation s .
Possible consequences if disregarded:
Death or most severe injuries
Caution! Warns of potential, hazardous situations.
Possible consequences if disregarded:
Light or minor injuries
Warnin g of damage
to material
Stop! Warns of potential d amage to material.
Possible consequences if disregarded:
Damage of the controller/drive system or its environment
More information Tip! Designates a general, useful note.
If you o bserve it, handling of the controller/drive system is made easier.
