5 Electrical installation
5.1 Safety precautions
Danger owing 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.
•
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 permissible 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.

5.2 EMC-compatible installation
5.2.1
Motor feeder cable
The applicable standard for interference emissions is EN 61000-6-3. Compliance with this standard is
achieved through the use of an unscreened motor feed cable.
5.2.2
Signal cable
Pay attention to suf
cient distance from powerlines and motor wires to prevent interferences. The
control cable may not be longer than 30 m. Screened control cables must be used when the cable
length is longer than 20 m. When using a shielded cable connect the shielding to one side only, i.e.
only to the control unit with the protective ground (keep cable short and with as little inductance as
possible!).
5.3 Mains connection
Power from the mains is connected to terminals: PE, L1 and N. Here, it must be strictly observed that
the mains voltage lies within the allowable tolerance speci
cations (

Danger owing to electric current
The mains voltage must comply with the DIN EN 50160 quality characteristics and the de
ned
standard voltages in IEC 60038!
