4.4
Installation location for agriculture
In order to avoid damage caused by ammoniac vapours, the controller shall not be installed in the
stable, but rather in an outhouse wherever possible.
4.5
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.
•
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 represented in the enclosure of this manual (
Connection diagram)!

EMC-compatible installation
5.2.1
Motor 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
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!).
5.2.3
Harmonics current for devices
≤
16 A
According to EN 61000-3-2 the devices are to be classi
fi
ed as
“
professional
”
devices. The application
is therefore limited to use by trade, certain vocations or industries.
Connection to a low voltage supply (public networks) is allowed insofar as this has been clari
fi
ed with
the respective energy supply company responsible.
Note: up to a maximum current of approx. 4 A, the limits are adhered to with no restrictions.
Exception for Germany: An energy provider follows the technical connection conditions of the
TAB2007, in which case the use of phase angle controlled devices up to a rating of 3.4 kVA per phase
is allowed.
