3.4 Installation Notes
A minimum open space of at least 100 cm. should be left in the front and back of the cabinet to provide for
operation and maintenance.
• Place the UPS in a clean, stable environment. Avoid places with excessive vibrations, dust,
humidity, flammable gas or liquid and corrosive substances. Room air-conditioners or extractor
fans are recommended to be installed. Optional air filters are available if the UPS operates in
a dusty environment.
• The environment temperature around the UPS should kept in a range of 0°C~40°C. If the
environment temperature exceeds 40°C, the maximum temperature cannot be higher than 50°C.
• Do not dismantle the UPS under low temperatures. It might cause condensing. The UPS cannot
be installed unless the interior and exterior temperature of the UPS is fully dry to prevent danger of
electric shock.
• Batteries should be mounted in an environment where the temperature is within the required specifications.
Temperature is a major factor in determining battery life and capacity. In a normal installation, the battery
temperature is maintained between 15°C - 25°C. Keep batteries away from heat sources or main air
ventilation area, etc.
• If the equipment is not going to be installed immediately, store it in a room to protect it against excessive
humidity and heat sources.
WARNING
Typical battery performance data are quoted for an operating temperature between
20°C - 25°C. Operating it above this range will reduce the battery life while operations
below this range will reduce the battery capacity.
CAUTION
An unused battery must be recharged every 6 months. This can be achieved by temporarily
connecting the UPS to a suitable AC supply mains activating it for the time required for
recharging the batteries.

The highest altitude that UPS may work normally with full load is 1500 meters.
The load capacity should be reduced when this UPS is installed in places whose altitude is
higher than 1500 meters, as shown in the following table

(Load coefficient equals maximum load in high altitude places divided by the nominal power of the UPS)
The UPS cooling depends on the fan. It should be kept in a well-ventilated area. There are many
•
ventilation holes on the front and rear which should not be blocked.
3.5 External Protective Devices
For safety reasons, it is necessary to install, an external circuit breaker at the input AC supply.
This section provides guidelines for qualified installers with knowledge of wiring for installing
the equipment.
UPS Output
Any external distribution board used for load distribution shall be fitted with protective devices that may
avoid the risk of UPS overload.
Over-current
Protection device shall be installed at the distribution panel of the incoming main supply. It may identify
the power cables current capacity as well as the overload capacity of the system.
CAUTION
Select a thermo-magnetic circuit-breaker with an IEC 60947-2 trip curve C (normal) for 125%
of the current as listed below.
