Follow the below procedures if you need to change or add a battery module, e.g. if you receive a display
message reporting a bad battery, or if you need to add batteries for increased runtime.
Installation.
If additional batteries are needed for extra runtime, or if you install battery replacement
modules, be aware of the following:
When removing Battery Modules, start from
the highest level and work down.
Holding the battery handle, gently push the
battery upwards and pull it halfway out of
the enclosure. A lock mechanism prevents it
from being pulled all the way out.
To release the battery from the lock
mechanism, gently push the battery upwards
again and pull it out, while another person
supports the battery.
Caution
Batteries must be replaced by trained personnel only (see the section General safety
prior to Battery Module replacement).
Caution
Do not install Battery Modules in the UPS until you are ready to power up the system.
Disregarding this caution can result in a deep discharge of the batteries and cause
permanent damage. The time between battery installation and powering up the UPS
should not exceed 72 hours or 3 days.
