Installation and Operating Specification FU Basic
• Before installation remove the device from the packing and check for any possible shipping
damage! Start-up is not allowed in the case of transport damage!
At a weight greater than 25 kg for men / 10 kg for women, the fan should be lifted out by two
•
persons (according to REFA). The values may differ from country to country.
Wear safety shoes and gloves for handling!
•
Assemble the device on a clean and stable base. Do not distort during assembly! Use the
•
appropriate mounting devices for proper installation of the unit!
A mounting on vibrating base is not permissible, if no data to the vibration strength is made (see
•
Technical data)!
• When mounted onto lightweight walls, there must be no impermissibly high vibrations or shock
loads. Any banging shut of doors that are integrated into these lightweight walls, can result in
extremely high shock loads. Therefore, we advise you to decouple the devices from the wall.
Do not allow drilling chips, screws and other foreign bodies to reach the device interior!
•
• Maintain the stated minimum clearances to ensure unobstructed cooling- air feed as well as
unobstructed outgoing air discharge (see minimum space requirement)!
The device should be installed in a location where it will not be disturbed, but at the same time can
•
be easily accessed!
Depending on the housing model cut off necessary cable inlets respectively to the cable diameter.
•
Or alternative use cable inlet for cable glands. Metal sheet housings are supplied with stoppers.
Any cable ducts openings not used must be sealed!
• Care must be taken to avoid direct radiation from the sun!
The device is designed for vertical installation (bottom cable inlet). A horizontal or reclined installa-
•
tion is only permissible after technical release of the manufacturer!
• Be sure to observe proper heat dissipation (see Technical data, heat dissipation).
4.2

Minimum space requirement

In order to ensure sufficient 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 influences during commissioning
Avoid condensation in the controller and functional faults attributable to condensation by storing the
controller at room temperature!
