6. Operation
If necessary, systems including controllers must be equipped with additional monitoring and protection devices
according to the applying safety regulations (e.g. regulation for technical equipment, regulation for the prevention
of accidents). The controller can be adapted to your application. Please observe the corresponding information given
in the Instructions.
After a controller has been disconnected from the voltage supply, all live components and power connections must
not be touched immediately because capacitors can still be charged. Please observe the corresponding stickers on
the controller.
All protection covers and doors must be shut during operation.
Note for UL-approved systems with integrated controllers: UL warnings are notes which only apply to UL
systems. The Instructions give UL-related information.
7. Safe standstill
The variant V004 of 9300 and 9300 vector, and the variant Bx4x of 8200 vector controllers support the function "Safe
standstill", protection against unintended start, according to the requirements of Appendix I No. 1.2.7 of the EC
Directive "Machinery" 98/37/EG, DIN EN 954-1 category 3 and DIN EN 1037. Please observe the notes on the function
"Safe standstill" given in the corresponding Instructions.
8. Maintenance and service
Please observe the Instructions given by the manufacturer,
and the product-specific safety and application notes in these Instructions.

L
Before working on the controller check that no voltage is applied to the power terminals, the
l
relay output and the pins of the FIF interface.
– because the power terminals U, V, W, BR1, BR2 and the pins of the FIF interface remain
live for at least 3 minutes after mains switch-off.
– because the power terminals L1, L2, L3; U, V, W, + UG, -UG, BR1, BR2 and the pins of the
FIF interface remain live when the motor is stopped.
– because the relay outputs K11, K12, K14 can remain live when the controller is
disconnected from the mains.
If you use the function "Selection of the direction of rotation", which is not protected against
l
open-wire, via the digital signal DCTRL1-CW/CCW (C0007 = -0- ... -13-, C0410/3 ≠ 255):
– The drive can reverse the direction of rotation in the event of a control-voltage failure or
an open circuit.
l If you use the function "Flying-restart circuit" (C0142 = -2-, -3-) with machines with a low
moment of inertia and a minimum friction:
– The motor can start for a short time or reverse the direction of rotation for a short time
after controller enable while the motor is at standstill.
The heatsink of the controller has an operating temperature of > 80 °C:
l
– Direct skin contact results in burnings.
All pluggable connection terminals must only be connected or disconnected when no voltage
l
is applied!
Cyclic connection and disconnection of the controller supply voltage with L1, L2, L3 can
l
exceed the input current limit:
– Allow at least 3 minutes between disconnection and reconnection.
Depending on the controller settings, the connected motor can be overheated:
l
– For instance, longer DC-braking operations.
– Longer operation of self-ventilated motors at low speed.
Drives can reach dangerous overspeeds (e.g. setting of inappropriately high field
l
frequencies):
– The controllers do not offer any protection against these operating conditions. For this,
use additional components.
