5.1 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.
•
The 5 electrical safety rules must be observed!
•
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.
•
Other measures may be necessary to achieve safe electrical isolation.
•
Connect fan only to electrical circuits that can be disconnected with an all-pole isolating switch.
•
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 device owner is responsible for the EMC of the entire plant according to the locally applicable
standards.
•
Inspect electrical equipment periodically: retighten loose connections – immediately replace dam-
aged lines and cables.
