Before commencing work inside the cabinet, the control cabinet manufacturer's instruction must be
read with regards to:

Safety instructions.

●

Instructions on taking the cabinet out of operation.

●

Instructions on the prevention of unauthorised cabinet reconnection.

●

The electric equipment meets the valid safety regulations. One can find dangerous voltages (above 50
V AC or above 100 V DC)

Behind the control cabinet doors.

●

On the power supply in the unit housing.

●

The unit has to be fused according to the type plate and the wiring diagram, and must be protected
externally from overloading and electrical faults via suitable protective devices such as ground fault
protection breakers.

Danger through incorrect work on the unit

The unit can only be installed and maintained by technical competent and
qualified personnel, using only supplied material according to the supplied
instructions.

󰾬

Danger from electrical voltage

Only specialised personnel are allowed to maintain and clean the unit. The

4. Technical information

The cooling unit is intended to be used as a complementary accessory to larger industrial
equipment. The unit is used where heat needs to be dissipated from electrical control cabinets or
similar enclosures in order to protect heat sensitive components. It is not intended for household use.
The unit has two completely separate air circuits which ensure that the clean cabinet air does not
come into contact with the ambient air which may well be dirty or polluted. Control cabinet cooling
units can dissipate large quantities of heat from sealed enclosures such as electrical enclosures into
the ambient air and at the same time reduce the cabinet internal temperature to below that of the
ambient air.
The unit can function without problems in extreme ambient conditions (e.g. dusty and oily air) with
a standard operating temperature ranging between -20°C and +55°C. Units can be ordered with an
additional electrical cabinet heater. For the cooling capacities and evironmental ratings please refer to
the type plate data.

7. Mounting

Always disconnect the power supply before opening the unit.

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. Air inlets and outlets must be completely free from obstruction.
Ensure that flows of air leaving and entering the cooling unit, internal and external, are not obstructed.
Cooling unit enclosure air suction hole must be installed in the highest possible point. When installing
the unit on a door ensure it can take the weight.
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.
