5. Mounting
Mounting preparations
Several points must be checked before the unit can be mounted. These checks must be made to ensure safety
and the trouble-free operation of the unit. These checks must be carried out with absolute thoroughness to
ensure that the unit works perfectly.
Check unit for transport damages
On delivery the carton box containing the unit must be examined for signs of transport damage. Any transport
damage to the carton box could indicate that the unit itself has been damaged in transit which in the worst case
could mean that the unit will not function.
Location and space requirements
The location of the cabinet must allow for sufficient air circulation to and from the unit.
Attention
Damage to the unit through incorrect mounting. The unit must be mounted according to the mounting template.
It is therefore also important to check, with the help of a spirit-level, that the cabinet is in a horizontal position.
Air apertures
To provide adequate air circulation and avoid temperature layers from forming, ensure that air inlet and air
outlet are not partially or completely blocked by obstructions in the cabinet.
Sealing
󰾬To guarantee that the unit works perfectly ensure that:
the control cabinet is completely sealed to min. IP54 according to EN 60529
a good seal exists between the control cabinet and the fan unit
Danger through high voltage
Ensure that for the duration of the mounting operation the cabinet is disconnected from the electrical supply.
Therefore take the cabinet out of operation, following the relevant instructions, before mounting work begins
and take all precautions to prevent premature reconnection of the cabinet. When all mounting preparations are
complete the actual mounting operation can commence.
Use of mounting template (not applicable for 19" rack mount units)
The supplied mounting template helps to mount the cabinet air conditioner quickly. Please proceed as follows:
Take the cabinet out of operation in the prescribed manner and secure it against unauthorized
reactivation
Fix the mounting template in the required position on the outer surface of the cabinet
Drill the holes and cut the apertures in the required positions in the surface of the cabinet and remove
the mounting template
Stick the self-adhesive unit seals on the outer surface of the cabinet for externally mounting and on the
inner surface of the cabinet for half in/half out mounting of the unit
The self-adhesive seals ensure a durable seal between the unit and the cabinet.
Mounting the unit
Only use the supplied material to mount the unit on the cabinet. Proceed as follows to secure the unit on the
cabinet:

Version Nr. 1-1 - 08.03.2020 Doc. Nr. 994855011 6 / 9
Set the unit up on the cabinet
Screw the M6 hex.head screws (if supplied) together with the washers and locking washers into the M6
threaded rivets in the unit
The resistance of the earth connection between cabinet and fan unit must be < 0.1 Ω.
