4.3
Installation location for agriculture
When using for animal keeping, do not install the device directly in the stable but in a separate room
with a lower pollutant load. This helps to avoid damages caused by pollutant gases (e.g. ammonia
fumes, hydrogen sulphide fumes).
4.4
Temperature in
fl
uences during commissioning
Avoid condensation in the controller and functional faults attributable to condensation by storing the
controller at room temperature!

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.
•
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!
•
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 manual (
Connection diagram)!
5.2
EMC-compatible installation of control lines
Pay attention to suf
fi
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
Here, it must be strictly observed that the mains voltage lies within the allowable tolerance speci
fi
ca-
tions (
Technical data and nameplate af
fi
xed to the side).
Danger due to electric current
The mains voltage must comply with the DIN EN 50160 quality characteristics and the de
fi
ned
standard voltages in IEC 60038!
