22.4. UZK24.122 – 24V, 12AH BATTERY MODULE
The UZK24.122 battery module, recommended for load currents up to 40A, which utilizes
two non-spillable maintenance-free VRLA lead-acid batteries with absorbent glass mat
(AGM) technology connected in series. It is assembled with 1.5m wire leads and fusing
included.
The battery module is available in two different options. It can be ordered as UZK-module
with batteries included or as UZO-module without batteries, which can be installed at a
later date. This option helps to avoid outdated batteries.
The battery module also includes a sensor board, which contains a temperature sensor and
a center-tap connection terminal. The use of the sensor board enables to monitor and
charge the two batteries individually and precisely. This extends the service life of the
batteries and makes the use of matched replacement batteries unnecessary.
The use of the sensor board is optional and the DC-UPS will function without the sensor
board installed.

22.5. UZK24.262 – 24V, 26AH BATTERY MODULE
The UZK24.262 battery module utilizes two non-spillable maintenance-
free VRLA lead-acid batteries with absorbent glass mat (AGM)
technology connected in series. It is assembled with all wiring and fusing
included.
For easier mounting and because of the high weight the battery holder
is made in two parts.
The battery module is available in two different options. It can be
ordered as UZK-module with batteries included or as UZO-module
without batteries, which can be installed at a later date. This option
