1.4 Remaining hazards
Units from the controller series UR are state of the art and safe to operate. A risk
of danger can occur when deployed and operated improperly by untrained
personnel.
In this manual remaining hazards are marked by the following warning symbol:
This symbol indicates that non-observance of the safety guide-
lines may cause hazards to persons even serious injury or death
and/or the possibility of property damage.
1.5 CE Conformity
The CE certicate is available at our company. We are pleased to send you a
copy of it. Please feel free and contact us to get a copy.
