11 System Cubicles, System Lighting and System Air-Conditioning Benefits Installing air-conditioning equipment in SIVACON sicube cubicle systems ensures high fault tolerance for switchgear and controlgear assemblies and consequently a high level of availability of machines and plants. Introduction Application In control cubicles, depending on the ambient conditions (e.g. heat, cold, air humidity etc.), there may be a tendency to overheat or for mold to form. In such cases the cubicles should be air-conditioned. The following air-conditioning equipment is available for this purpose: Filter fans Air conditioners/cooling devices Heat exchangers, air/air Heaters/thermostats When selecting individual air-conditioning components, the ambient temperature, the power losses of the installed devices, the maximum permissible device temperature and the heat dissipation capacity of the cubicle used are the factors to be considered. In addition, it is necessary to take into account the required degree of protection.

13 System Cubicles, System Lighting and System Air-Conditioning Filter fans Overview Filter fans are the most cost-effective method - after heat dissipation through the surface of a control cubicle and/or ventilation openings in the enclosure parts of the control cubicles - for dissipating heat from control cubicles. However, this can only achieve a control cubicle temperature which lies above the ambient temperature. Standard filter fans optionally in EMC version When filter fans are used for air-conditioning, the cubicle must have openings which allow electromagnetic radiation to pass in and out unobstructed. Filter fans in EMC version offer additional protection when higher requirements are imposed on electromagnetic compatibility. Filter fan versions The following filter fans are available on request: Standard filter fan IP54, color RAL 7035/7032 Standard filter fan IP55, color RAL 7035/7032 Standard filter fan EMC, color RAL 7035/7032, IP54 Standard filter fan EMC, color RAL 7035/7032, IP55 Note: For all standard filter fans the useful cooling capacity and air rate are reduced by an average of 30 % in combinations of filter fan / outlet filter / filter mat, and for roof filter fans by 40 %.

21 System Cubicles, System Lighting and System Air-Conditioning Thermostats, hygrostats, hygrotherms, switching modules Overview Tamper-proof thermostat, NC contact Thermostats Thermostats (as NC, NO or CO contacts) are used to regulate cooling devices, filter fans and heat exchangers, as well as to trigger signals in case of excessive temperatures. Hygrostats Hygrostats are used to regulate heaters/fan heaters so that the temperature increase raises the dew point from a critical humidity of 65 % in cubicles and enclosures with built-in electrical and electronic components. This prevents condensation on structural parts and electronic components. Hygrotherms Hygrotherms monitor both temperature and relative humidity in cubicles and enclosures with built-in electrical/electronic components and switch on a heater or fan upon reaching the selected values (temperature or relative humidity). This prevents condensation on structural parts and electronic components. Switching modules Switching modules are electronic relays for the switching of high-power DC devices. Thermostats, hygrostats or hygrotherms can be connected to operate the switching modules. Note: The switching capacity values quoted in brackets refer to inductive loads.
