3. Transportation and placement
The UPS system installation, including the modular battery cabinet, must meet the following guidelines:
- The support surface must be scaled in for the carrying capacity necessary to support the equipment.
- Dust or corrosive/explosive gasses must be absent.
- The site must be free of vibration and there should be enough lighting.
- The system must be installed in a temperature and humidity controlled indoor. The ambient temperature range is 0-40°C
(32-104°F) with a maximum relative humidity of 95%, non-condensing. However, the recommended operating range is
20-25°C (68-77°F) to ensure nominal battery lifetime.
- The rear and side space must be enough to guarantee an adequate circulation of air for cooling.
- The cooling flow of air must be guaranteed.
- The external battery cabinet must be accessible on all sides for assistance or periodic servicing.
WARNING
The battery cabinet should be installed in a room with adequate air ventilation flow to avoid dangerous concentration
of hydrogen gas that can be produced during battery recharge. The maximum concentration of hydrogen in the room
should be kept below 0,8% by volume. The room ventilation air flow should be adequate to renew the air especially in the
volume of the room above the battery cabinets and below the ceiling where the hydrogen gas concentrates. The neces-
sary minimum air flow in m3/hour is depending on the battery technology, the number of cells, the nominal cell capacity.
Refer to stationary battery installation standards and battery manufacturer recommendation.
INDICATION
Operating temperatures above the recommended range will result in decreased battery life and performance and will
reduce or void the battery warranty.
