Safety precautions
Danger due to electric current
•
Work on electric components may only be carried out by trained electricians or by persons
instructed in electricity under the supervision of an electrician in accordance with electrical
engineering regulations.
•
It is forbidden to carry out work on electrically live parts. Even after disconnection, the dc-
link is still live. Always wait at least 3 minutes.
•
A second person must always be present when working on energized parts or lines who
disconnects in case of emergency.
•
Inspect electrical equipment periodically: retighten loose connections
–
immediately replace
damaged lines and cables.
•
Always keep switch cabinets and all electrical supply facilities locked. Access is only
allowed for authorized persons using a key or special tool.
•
Operating the device with the housing cover removed is prohibited because energized,
exposed parts are present inside the device. Disregarding this regulation can lead to severe
personal injury.
•
The required protective earth connection is established using screws between the housing
parts in metal terminal space covers and housing casings. Commissioning is only permis-
sible after these screws have been properly attached!
•
Metal screwed-connections are not permitted in plastic housing parts because there is no
potential equalization.
•
Never clean electrical equipment with water or similar liquids.
