Battery drawers replacement
WARNING
A battery can present a risk of electrical shock and high short circuit current. Read and apply the safety instructions in
chapter 2 before operating on batteries
INDICATION
The battery drawers must always be added/removed in multiples of two (1 KB consists of two battery drawers). Always
replace just one KB at a time. If one KB is added, start from the free slots at the top which are covered by protective covers.
If a KB is completely removed, install the protective covers to block any access to live parts.
If the installation/removal procedure changes the total number of KB installed in the UPS, it is necessary to update this
setting from the control panel.
After concluding the installation/replacement operations, perform a battery calibration to get precise information re-
garding the total autonomy of the UPS.
