In case of parallel system, try to place the UPS modules in sequence of their numbers (marked on
the packing).
If the units are positioned "side by side", the side panels must be mounted on all units.
3.4.2 Battery location
Batteries require a well-ventilated room with controlled temperature to obtain reliable operation.
The battery can be install immediately adjacent to the UPS (left or right side) or remotely from the UPS.
If the battery is installed remotely from the UPS, a wall mounted DC disconnect device must be installed
within line-of-site to both the UPS and the battery.
The optimal room temperature for Battery storage is 68°F (20°C) to 77°F (25°C) and shall never exceed
the range -4°F (-20°C) to 104°F (40°C).
The life of valve-regulated batteries will be reduced by 50% for each additional 18°F (10°C) that the
battery ambient temperature is above 77°F (25°C).
The battery system associated with larger UPS is usually either rack mounted or installed in multiple
battery cabinets.
Installation and assembly must be made according to the local standards and battery system
manufacturer's recommendations.
The battery circuit breaker or battery fuse box must be mounted as near as possible to the battery.
NOTE !
Battery installation and connection must be performed by QUALIFIED SERVICE
PERSONNEL ONLY.
Read all safety instructions before proceeding with the installation.
