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 re-
place 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 hous-
ing 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.
Information
The respective connections are representedin the enclosure of this manual (

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
achievedthrough the use of an unscreenedmotor feedcable.
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. Screenedcontrol cables must be usedwhen 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 andwith as little inductance as
possible!).
5.3 Mains connection
Power from the mains is connectedto terminals: PE, L1 andN. Here, it must be strictly observedthat
the mains voltage lies within the allowable tolerance speci
cations (

xedto the side).
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!
