Additional information
All internal batteries for all UPS units are charged to approximately 80 percent prior to
shipping. The UPS is shipped with the internal battery connector disconnected, as to avoid
premature discharge of the battery. The battery is expected to last at least six (6) months from
manufacture date, before requiring a recharge of the battery. Should the UPS be kept in
storage after that first recharge, subsequent recharge(s) should be repeated every six months.
Batteries must be connected before and disconnected after each recharge. However, it is
recommended, the batteries should not be recharged more than twice. This may limit the
overall battery storage period to not more than 18 months.
The recharge period for a battery is 48 hours without any load attached to the UPS.

If the storage time is longer than the recharge date, the battery of the UPS unit may drain
completely. In this case, the batteries cannot be recharged anymore. The battery is considered
to be damaged and must be replaced. The replacement of such failing batteries and Extended
Battery Modules is not covered by unit warranty or service contract.
Batteries not detected after installation of one or more EBMs
Issue
The UPS is equipped with one or more Extended Battery Module(s), EBMs.
When powering up the UPS unit the error LED of the UPS is lit and the UPS will sound a
continuous beep which may need to be manually silenced. This is an indication that the UPS
does not detect the batteries.
The EBM circuit breaker is in the "Off" position.
Solution
In order to connect one or more EBMs correctly to a UPS unit two connections are required,
one for the actual power connect and the EBM detection cable. Once the connection has been
made the EBM circuit breaker needs to be switched to the "On" position. The EBM circuit
breaker can also be switched to the "On" position if the UPS unit is already in production.
