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.
•
The 5 electrical safety rules must be observed!
•
It is forbidden to carry out work on electrically live parts. Even after disconnection, the dc-link is still
live. Always wait at least 3 minutes.
•
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 discon-
nects in case of emergency.
•
Inspect electrical equipment periodically: retighten loose connections
–
immediately replace dam-
aged 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.
•
For metal cable inlets the necessary protective earth connection to the bottom of the housing is
made by screws. The device may only be started up when these screws are
fi
tted properly.
•
The device owner is responsible for the EMC of the entire plant according to the locally applicable
standards.
•
Never clean electrical equipment with water or similar liquids.

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
Control cables
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
5.3.1
Line voltage
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
