cabinet on which the unit is to be mounted.

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

personnel must ensure that for the duration of the maintenance and cleaning, the

unit is disconnected from the electrical supply.

Attention

4. Technical information

The cooling unit is intended to be used as a complementary accessory to larger industrial equipment,

and is used where heat needs to be dissipated from electrical control cabinets or similar enclosures in

order to protect heat sensitive components. 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. The cooling unit can dissipate large quantities of heat from electrical enclosures into

the ambient air and at the same time reduce the internal temperature to below that of the ambient

air. The unit works without problems in extreme ambient conditions (e.g. dusty and oily air).

The operating temperature range is 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.

5. Functional principle

The unit functions on the principle of the compression refrigerator. The main components are:

refrigerant compressor, condenser, choke and evaporator. these four components of the refrigerant

plant are connected with each other by pipes to form a hermetically sealed system in which the

refrigerant (R134a) circulates. R134a is chlorine free and has an Ozone Destruction Potential [ODP] of

0 and a Global Warning Potential [GWP] of 1430.

8. 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.

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.

Use of mounting template

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.

Version Nr. 25 - 29.10.2016 Doc. Nr. 9945551001 8 / 19

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:

Set the unit up on the cabinet

●

Screw the M6 hex. head screws together with the washers and locking washers into the M6 threaded

●

rivets in the uni

The resistance of the earth connection between cabinet and cooling unit must be < 0.1 Ω󰾬.
