Safety regulations
•
The unit may only be installed and operated by those who are qualified electrical engineers or have received sufficient train-
ing and are familiar with both these instructions and the current regulations for safety at work and accident prevention. Fol-
low VDE, EN as well as local regulations especially as regards preventative measures!
•
Ignoring the safety regulations can lead to death, serious injury or cause considerable damage!
•
In emergency stop applications use the internal function “Speed output restart disable” or a higher level control unit must

. See technical details
•
Any guarantee is void following unauthorised modifications. This can lead to death, serious injury or cause considerable
damage!
•
The unit should be cabinet mounted, otherwise dampness or dust could lead to functional impairment.
•
Adequate fuse protection must be provided on all output contacts especially with capacitive and
inductive loads.
•
The unit must be installed following the specification of
DIN EN 50274, VDE 0660-514
regarding the required distances.
•
