7. Mounting
The power supply rating on unit rating plate must comply with mains
rating.
Always disconnect the power supply before opening the unit.
The heat load to be dissipated from enclosure should not exceed specific cooling output of the unit at any
condition. At cooling unit selection always cater for a safety margin of at least 15% extra cooling output in the
worst conditions.
Ensure that flows of air leaving and entering the cooling unit, internal and external, are not obstructed. 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.
Before drilling the enclosure ensure the fixing elements and couplings will not interfere with the equipment
inside the enclosure itself. Disconnect power before starting any work inside the enclosure. Following this 1:1
Scale Drilling Template drill the holes and make the required cuts on the enclosure. This template may have
been affected by storage conditions, please check this template by verifying values of the largest dimensions
before drilling. Fit the sealing strip on the cooling unit on the side connected to the enclosure and follow the
installation diagram.
Note: In case of 19" rack mounted units please ignore the above mounting instructions.
