3.2. 3 Installation of Battery

During the installation design of UPS system, please use batteries approved by supplier. Without permission, it is
forbidden to use batteries of other brands because UPS is excluded from the warranty for damage of UPS caused
by batteries of other brands. If the batteries of other brands are used, please contact local distributor.
For the installation method, please see the battery installation instructions shipped with the battery.
