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.
Remove the side air inlet grids on the intermediate units to run the control bus cable
connections.

4.4.6 Battery location

Batteries require a well-ventilated room with controlled temperature to obtain reliable operation.
The Battery can be installed 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 Battery 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 must be mounted as near as possible to the Battery.
Warning!
Battery installation and connection must be performed by Qualified Personnel only.
Read all safety instructions before proceeding with the installation (see Chapter 1).
Battery discharging and/or charging activities may cause the emission of hydrogen gas; therefore,
the room requires proper ventilation and fresh air.
Comply with the UL1778-CSAC22.2no170.3 UPS safety standard, ANSI/IEEE P1184 Guide for
Batteries for Uninterruptible Power Supply Systems and applicable codes and governmental
regulations.
