Version No. 1-4 - 04.09.2023 Doc. No. 993200310 4 / 16
3. Safety instructions
Upon delivery the unit is already meeting current technical standards and can therefore be safely taken into
operation. Only authorised personnel is allowed to work on the unit. Unauthorised personnel must be prohibited
from working on the unit. Operating personnel must inform their superiors immediately of any malfunction of
the unit.
Please note that before starting to work on or with the unit, a procedure must be carried out inside the 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 operated according to the type plate and the wiring diagram, and must be protected
externally from overloading and electrical faults via suitable protective devices.
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
Damage to the unit through the use of inappropriate cleaning materials. Please do not use
aggressive cleaning material.
Instruction
Damage to the environment through unauthorised disposal. All spare parts and associated
material must be disposed according to the environmental laws.

4. Settings
Peltier cooling units are intended to be used as a complementary accessory to larger industrial equipment. They
are used where heat needs to be dissipated from electrical control cabinets or similar enclosures in order to
protect heat sensitive components.
Peltier cooling units can dissipate heat from sealed enclosures such as control cabinets. At the same time they
can reduce the cabinet internal temperature to below the ambient air temperature. They are available in
powder-coated sheet steel or stainless steel housings. Peltier units have additional heating function by changing
the supply polarity of the thermoelectric elements. This is possible by using a combination of thermostats or
having a specific polarity controller.
Peltier air conditioners are resistant to extreme ambient conditions and can operate effectively even in
environments which are dusty and oily and where temperatures may vary from -20°C to +65°C. For the cooling
capacities and environmental ratings please refer to the type plate data.
5. Functional principle
The thermoelectric elements create a temperature difference between the internal and ambient heat sinks,
making internal air cooler while dissipating heat into the external environment. Fans help the transfer of
convective heat from the heat sinks, which are optimized for maximum flow. Peltier units be mounted in any
position because these units don’t have a compressor and no moving parts.

8. Mounting
Always switch off power supply before starting any work on the unit.
Installation
Ensure that flows of air leaving and entering the cooling unit, internal and external, are not obstructed. Before
drilling the enclosure, ensure the fixing elements and couplings will not interfere with the equipment inside the
enclosure itself. When all mounting preparations are complete the actual mounting operation can
commence. Only use the enclosed material to mount the unit on the cabinet.
Proceed as follows to mount the unit on the cabinet:
• Set the unit up on the cabinet.
• Ensure that the electrical connection is above the internal fan.
• Unit without duct: screw the M5 or M6 locknuts & washers into the M5 or M6 set screws in the unit.
• Unit with duct: screw the M5 or M6 screws & washers into the M5 or M6 threaded rivets in the unit.
The resistance of the earth connection between the enclosure and cooling unit must be <0.1Ω.

9. Condensate management
Depending on the mounting situation the condensation management may need to be considered and possibly
adjusted.
10. Mounting Principle
In order to maintain the stated protection ratings, the tightening torque for this unit should be 4.5 Nm and
needs to follow the below sequence.
