4.2
Minimum space requirement
In order to ensure suf
fi
cient ventilation of the device, clearance on all sides of at least 50 mm has to
be maintained to the housing walls, switch cabinet doors, wiring ducts, etc. The same clearance
applies to the installation of several devices next to each other.
When installing several devices on top of each other, the danger of reciprocal heating exists. This
layout is only then permissible when the air suctioned from the upper unit does not become warmer
than the permissible ambient temperature (see Technical data). I.e., a correspondingly larger clear-
ance or thermal shielding is required.
4.3
Outdoor installation
Outdoor installation is possible up to -20
°
C when the controller supply is not switched off. Installation
must be protected from the effects of weather as much as possible, including protection from direct
sunlight!
4.4
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).
4.5
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.
•
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.
•
Electrical equipment must be checked regularly: Loose connections are to be re-tightened and
damaged lines or cables must be replaced immediately.
•
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.
