ESCRIPTION
The UZK12.261 battery module utilizes one non-
spillable maintenance-free VRLA lead-acid battery,
which is assembled in a package with all wiring and
fusing included.
The battery module is available in two different
options. It can be ordered as UZK-module with a battery
or as UZO-module without a battery which can be
installed at a later date to avoid outdated batteries.

TORAGE
Do not store batteries or battery modules at temperatures higher than 25°C or performance and lifetime may change.
Do not store discharged batteries. Keep batteries fully charged!
Charge retention is important to get the longest battery life. Stored batteries which are not fully charged age faster
then charged batteries.
Do not store batteries longer than 9 months without charging or performance and lifetime may change. Every 9
months or whenever the open circuit voltage (OCV) falls below 12.6V, the battery module should be charged. Apply a
charging voltage of 13.8V (at 25°C) for 72 hours. Batteries with an OCV below 12V must not be charged anymore and
must be disposed.
8. INSTALLATION INSTRUCTIONS
This device may only be installed and put into operation by qualified personnel.
Before initial use, check the last charging which is marked on the battery. If it is older than 9 month, replace the
battery.
Do not install the battery fuse until the installation work is complete.
This device does not contain serviceable parts, except the fuse or replacement battery. If malfunction should occur
during installation or operation, first check the fuse and battery for proper functionality. If the unit is damaged or if
the malfunction continues, immediately turn power off and send device to the factory for inspection.
Replacement fuses must be of the same type or an UL listed fuse with the same nominal value and characteristics.
Do not short-circuit the battery poles or power wires and always check correct battery polarity.
Mount the device onto a flat surface. Do not install the battery module upside down.
Place the battery module in a cool area inside a cabinet.
Install the device in an enclosure providing protection against electrical, mechanical and fire hazards. Ensure sufficient
ventilation by following the requirements of the EN 50272-2.

To replace battery:
1) Loosen screw with only one turn.
2) Unscrew the battery terminals.
3) Slide the mounting bracket sideways and
take the mounting bracket off.
4) Remove the battery.
5) To insert the new battery use same
procedure vice versa.

Temperature:
The temperature has the most impact on the service life. The hotter the temperature, the earlier the wear-out phase
of the battery begins. The wear-out results in a degradation of battery capacity. Place the battery module in a cool
location, e.g. near the bottom of the control cabinet. Do not place the battery module near heat generating devices.
Do not overcharge batteries!

Number of discharge cycles and depth of discharge:
Do not discharge batteries more than necessary. Set buffer time limiter to the required buffer time. The number, as
well as the depth of discharging cycles is limited. A replacement of the battery might be necessary earlier.
When choosing the battery capacity, always try to get the next higher capacity than required. The depth of discharge
reduces the service life of the battery and limits the number of cycles.

Store batteries fully charged
Do not store discharged batteries. Keep batteries fully charged!
Charge retention is important to get the longest battery life. Stored batteries which are not fully charged age faster
then charged batteries. Batteries which are not in use should be recharged at least once a year. The higher the
ambient temperature, the shorter the charging interval. At storage temperatures higher than 30°C, recharging should
be done at least every nine months.
