5 Electrical installation
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.
•
Cover neighbouring electrical equipment during installation work.
•
Other measures may be necessary to achieve safe electrical isolation.
•
A second person must always be present when working on energized parts or lines
who disconnects in case of emergency.
•
Electrical equipment must be checked regularly: Loose connections are to be re-
tightened and damaged cables must be replaced immediately.
•
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 permissible after these screws have been properly attached!
•
The device owner is responsible for the EMC of the entire plant according to the
locally applicable standards.
•
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.
Information
The respective connections are represented in the enclosure of this Operating
Instructions (see connection diagram)!
5.2 EMC-compatible installation of control lines
To avoid interference, suf
fi
cient space must be left for power and motor cables. The
control cables can have a maximum length of 30 m and must be shielded above 20 m.
When using a shielded cable the shield must be connected to the PE conductor on one
side, i.e. only on the device side, e.g. using a shield connection terminal on the top hat
rail (as short and with as low an induction as possible).
