7. 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.
The max. deviation from the vertical or horizontal is 3 degrees.
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. It must also be ensured in
accordance with UL, that the air outlet is not blowing air directly at an equipment operator. Should this be the
case a barrier or duct shall be provided to redirect the airflow.
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 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.
