Safety concept

WARNING
Danger due to modified safety equipment
Non-functioning or defective safety equipment can cause severe accidents.
 Any changes to the unit, particularly the safety equipment, are prohibited.
 In case of defective safety equipment, shut down the unit and decommission it immediately.
• Cooling units have a pressure switch tested in accordance with EN 12263. It reacts to a pressure increase in the
refrigerant circuit by shutting off automatically.
• Fans and compressors are protected from overloading and overheating: e.g. the compressor is protected
against overclocking.
Additional protective functions (only cooling units with anti-freeze option):
• If there is a risk of ice formation, switch off the compressor and the fans.
• This shut-off function is not withdrawn until a system restart.
2.4.5

Accumulation of condensate

NOTE
Condensate flowing back into the switch cabinet can damage the electronic components
Internal temperatures below the dewpoint or damaged switch cabinet seals cause excessive accumulation of
condensate.
 Regular inspection of the seals assures protection against heavy condensate accumulation.
 Installation of a door contact switch reduces the accumulation of condensate when the switch cabinet is
open.
If the evaporator cools down, condensate can accumulate. In order to prevent damage to the switch cabinet and
the cooling units, the condensate is removed. The integrated condensate evaporator releases the condensate to
the environment. For safety reasons, there is a drain port with drain hose on the condensate evaporator.
 Accumulating condensate is collected by a condensate collecting bottle. It is available as an accessory.
 In case of questions about the cooling units or accessories and spare part orders, always specify the serial
number; see Spare part orders.
