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. 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. 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 vertically. 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

●

if necessary the cabinet mounting surface should be reinforced

●

Danger from electrical 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 mounted 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.

Version Nr. 1-1 - 20.06.2017 Doc. Nr. 9920250241 7 / 16

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

0.1 Ω󰾬.

Condensation drain pipe connection

The condensation drain is in the base of the unit. The condensation drain pipe should be attached as

required e.g. in conditions of high humidity.

If a pipe is required it should be attached as follows:

Remove the plastic stopper from the condensation drain in the base of the unit

●

Attach a pipe connection to the drain outlet and fix the condensation pipe onto it

●

Route the pipe to a drain or a collector

●

9. Electrical connection

High electric voltage present. Installation, maintenance, cleaning and

any other work must be carried out by qualified personnel only. The

personnel must ensure that for the duration of this work the unit and

the cabinet are disconnected from the electrical supply and protected

against unauthorised/accidental reconnection.

Note: As soon as preperations are finished, mounting procedures may proceed.

Connection to the main electrical supply

The mains connection is made via a connector / terminal block. To connect the unit to the mains

proceed as follows:

Take the control cabinet out of operation in the prescribed manner.

●

See the connection details on the circuit diagram.

●

Note the connections on the connector / terminal block from the following table

●

Normal (with power on) Alarm (normal with power on)

Terminal

1 + +ve supply

2 - -ve supply

3 T1 Door contact (bridged with T2)

4 T2 Door contact (bridged with T1)

5 P1 Alarm contact

6 P2 Alarm contact

7 P3 Alarm contact

Version Nr. 1-1 - 20.06.2017 Doc. Nr. 9920250241 8 / 16

Attention

Between contact T1 & T2 there is a 12V DC potential. These connections are to be connected to a door

switch only! If no door switch is used, these contacts are to be bridged and protected from

unauthorized and/or accidental external contact. Contacts P1, P2 & P3 are potential free and require

an external power source if wired to operate external components (indicator lamps, switches...). The

load on these contacts is not to exceed 30V DC, 4 A or 120/250V AC, 4A. If wired to external

components it must be ensured that the wiring and connections are double insulated and safe against

touch and protected from unauthorized and/or accidental external contact.

Ensure that the correct polarity is maintained. The fans should have

clockwise rotation.

Fault warning connection

The fault warning is connected via terminals P1, P2 & P3 on the connection terminal block. The temp.

adjustment range is between 25°C (left-hand stop) and 55°C (right-hand stop). The alarm temp. is

preset at 50°C.

Version Nr. 1-1 - 20.06.2017 Doc. Nr. 9920250241 10 / 16

To change the alarm setting:

Remove the outer cover.

●

Remove the fixing screws from the PCB cover and the earth wire from inside it.

●

Lift off the PCB cover

●

Using a screwdriver turn the alarm temp. potentiometer on the PC-board slightly to the right (higher)

●

or the left (lower)

please note that the setting for the alarm signal must be at least 5°C higher than the setting for the

●

cabinet's internal temperature

Close the unit as prescribed.

●

Check that the new setting meets requirments and if not repeat the above process.

Door contact switch connection

If required the unit can be switched on or off via a door contact switch (terminal T1&T2). When

delivered the door contact terminals are bridged.

To connect the door contact switch:

Remove the bridge from terminals T1 & T2.

●

Connect the door contact switch to terminals T1 & T2.

●

The contact must be closed when the cabinet door is closed.
