Positioning
UPS and batteries are designed for indoor use; UPS must be placed in a places where has clean
and easy air flow.
3.1.3.1.
Positioning
of
UPS
In Challenger 80‐120 kVA series, air enters the device from the front side ventilation holes, goes
out from the rear side of UPS through fans. Air inlet and outlet ports should never be covered. It
should be positioned in a place where is far from the risk of liquid contact.
If the area is dusty, Optional filters must be used on dusty environments.
The using of these filters will be made according to the instructions on.
UPS is an energy‐loss system due to its nature. Energy losses emerges as heat. You can see what
kind of a forced air‐cooling is needed in the following table. This table can be used to calculate the
capacity of air conditioning which must be used in UPS ambiance.

Configration
Batteries must be used in balanced and uniform temperature environments. temperature, is the
most important factor that directly affect to battery capacity and usage lifes. in general, battery
manufacturers recommend the batteries to be used between 20‐25 °C. In addition, Battery
manufacturers give the performance of their products in this temperature range. If temperature
exceeds this specific limits, battery life will decrease. If the temperature drops below this range,
the battery capacity is severely reduces. Therefore, the expected autonomy time will not be
sufficient during redundancy process. As a result, keep the batteries away from the points where a
heat source and serious air flow are located. Please observe the following points on connecting
external batteries by taking into account these issues:
Keep batteries away from main heat sources.
Keep batteries away from main air inlets.
Keep batteries away from the humid places.Hereby batteries can be prevented from terminal
oxidations and possible leakage currents.
Please use aR or gR semi‐conductor type fuse at the battery rooms and cabinets.
If it is possible, please use breaker switch without fuse for the bateery cabinet.
Keep battery cabinets and shelves high above the ground. UPS should be protected against floods
or liquid contacts.
Battery rooms should be properly ventilated.
