Storage
3.3.1 UPS storage
If you plan to store the UPS prior to use, it should be kept in a clean, dry environment with an ambient
temperature between -25°C to +70°C and relative humidity of less than 90%.
If the UPS is removed from the packing container you must also ensure you protect it from dust.
3.3.2 Battery
The storage capability of the UPS batteries depends greatly on the ambient temperature. It is important not to
store the UPS batteries for longer than 6 months at 20°C, 3 months at 30°C or 2 months at 35°C storage
temperature without recharging the battery.
For longer term storage the battery must be fully recharged every 6 months @20°C.
CAUTION: Sealed batteries must never be stored in a discharged or partially discharged state.
Extreme temperature, under-charge, overcharge or over-discharge will destroy the batteries!

Positioning
3.4.1 Planning the installation
A certain amount of pre-planning will help ensure smooth, trouble-free equipment installation. The following
guidelines should be taken into account when planning a suitable UPS location and environment.
1.
The equipment must be installed and transported in a upright position.
2.
The floor at the installed location and en-route from the off-loading point must be able to safely take the
weight of the UPS and battery equipment plus fork lift during transit. The floor material where the UPS is
to be located should be non-flammable.
3.
The UPS cabinet requires space to bottom/front and back to enable cooling airflow. Allow a minimum of
200mm clearance at the back of the cabinet. Suitable ventilation airflow (not exceeding +40°C) must be
provided (See Figure 3.2).
4.
All parts of the UPS requiring access for maintenance, servicing and user operation are accessible from
the front and rear. Reserve a minimum of 900mm space at the front of the UPS cabinet.
5.
An ambient temperature of 20°C is recommended to achieve a long battery life.
6.
Avoid high ambient temperature, moisture and humidity.
In summary
The UPS should be located where:
a) Humidity (< 90% non-condensing) and temperature (+15°C / + 25°C) are within prescribed limits.
b) Fire protection standards are respected.
c)
Cabling can be performed easily.
d) A minimum 900mm front accessibility is available for service or periodic maintenance.
e) Requested air cooling flow is available.
f)
The air conditioning system can provide a sufficient amount of air cooling to keep the room at, or
below, the maximum desired temperature.
g) No dust or corrosive/explosive gases are present.
h) The location is vibration free.
i)
If the UPS is to be installed in bayed enclosures, partition walls have to be installed.
