Disposal
In accordance with the current provisions, inverters and accessories have to be disposed of by
means of pr
ofessional recycling. Inverters contain recyclable raw material such as metal, plas-
cs an electronic components.
Residual hazards
Even if notes given are taken into consideraon and protecve measures are implemented,
the occurrence of residual risks cannot be fully prevented.
The user must take the residual hazards menoned into consideraon in the risk assessment
for his/her machine/system.
If the above is disregarded, this can lead to severe injuries to persons and damage to prop-
erty!
Protecon of persons
Before working on the inverter, check if no voltage is applied to the power terminals.
•
Depending on the device, the power terminals X105 remain live for up to 3 ... 20 minutes.
•
The power terminalsX100 and X105 remain live even when the motor is stopped.
Motor protecon
With some sengs of the inverter, the connected motor can be overheated.
•
E. g. by longer operaon of self-venlated motors at low speed.
•
E. g. by longer operaon of the DC-injecon brake.
Protecon of the machine/system
Drives can reach dangerous overspeeds.
•
E. g. by seng high output frequencies in connecon with motors and machines not suita-
ble for this purpose.
•
The inverters do not provide protecon against such operang condions. For this purpose,
use addional components.
Switch contactors in the motor cable only if the controller is inhibited.
•
Switching while the inverter is enabled is only permissible if no monitoring funcons are
acvated.
Motor
If there is a short circuit of two power transistors, a residual movement of up to 180°/number
of pole pairs can occur at the motor! (For 4-pole motor: residual movement max. 180°/2 =
90°).
Parameter set transfer
During the parameter set transfer, control terminals of the inverters can adopt undened
states.
•
Thus, the control terminal of the digital input signals have to be removed before the trans-
fer.
•
This ensures that the inverter is inhibited. The control terminals are in a dened state.
