Operation
DANGER
Risk of injury from electric shock or restarting motors!
The non-observance of warnings can result in severe bodily injury or sub-
stantial property damage.
 Observe the following instructions during operation:
 The drive controller operates at high voltages.
 When operating electrical equipment, certain parts of the equipment carry
dangerous voltage.
 Emergency stop devices according to EN 60204-1:2006 must remain op-
erative in all operating modes of the control unit. Resetting the emergency
stop device must not lead to uncontrolled or undefined restart.
 Safe disconnection from the mains requires synchronous and all-pole dis-
connection of the mains supply line to the drive controller.
 For devices with single-phase supply and for the BG D (11 to 22 kW), at
least 1 to 2 min break should be kept between successive connections to
the mains.
 Certain parameter settings may cause the drive controller to restart auto-
matically after a power failure.
NOTICE
Risk of damage to the drive controller!
The drive controller can be damaged in the case of non-compliance with
the instructions and destroyed during subsequent handling.
1. Observe the following instructions during operation:
2. For a functioning motor overload protection, the motor parameters must be
configured correctly.
3. Ensure the motor overload protection via a PTC. In addition, the drive control
provides an internal motor protection. See also parameter 33.100 and 33.101.
According to the presetting, the I
2 T is OFF and must be activated during op-
eration without PTC.
4. The drive controller must not be used as an 'emergency stop device' (see EN
60204-1:2006).
Maintenance and inspection
Maintenance and inspection of the drive controllers must be performed only by
electrically certified, qualified person. Changes in hardware and software, unless
explicitly described in this manual, may only be performed by the manufacturer.
Cleaning the drive controllers
The drive controllers are maintenance-free when operated properly. In a dusty en-
vironment, the cooling ribs on the motor and the drive controller must be cleaned
regularly. For equipment that are equipped with integrated fans, option for BG C,
series in BG D, cleaning with compressed air is recommended.
Measurement of insulation resistance on the control unit
Insulation test at the input terminals of the control card is not permitted.
