Controller protection
All pluggable connection terminals must only be connected or disconnected when
l
no voltage is applied!
Cyclic connection and disconnection of the supply voltage can overload and
l
destroy the input current limitation of the controller:
– In case of cyclic mains switching over a longer period of time three minutes have
to pass between two starting operations!
Motor protection
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.
Controller/system protection
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.
Contactors in the motor cable Switching with inhibited controller only.
l
If contactors in the motor cable are switched with the controller enabled,
– monitoring functions of the controller can be activated.
– the controller can be destroyed under unfavourable operating conditions.
Warnings!
The device has no overspeed protection.
l
Must be provided with external or remote overload protection.
l
Suitable for use on a circuit capable of delivering not more than 5000 rms
l
symmetrical amperes, 240 V maximum (240 V devices) or 500 V maximum
(400/500 V devices) resp.
Use 60/75 °C or 75 °C copper wire only.
l
Shall be installed in a pollution degree 2 macro−environment.
