ESCRIPTION
The UZK12.071 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installed at a later date to avoid outdated batteries.
The battery module can either be mounted on a DIN-rail
or be screwed on a flat surface.

Do not store batteries or battery modules at temperatures higher than 25°C or performance and lifetime may change.
Before initial use, check the last charging which is marked on the battery. If it is older than 9 months, replace the
battery.
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 should be disposed.

NSTRUCTIONS
This device may only be installed and put into operation by qualified personnel.
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.
Do not install the battery fuse until the installation work is complete.
Replacement fuses must be of the same type or an UL listed fuse with the same nominal value and characteristics.
Do not store batteries or battery modules at temperatures higher than 25°C or performance and lifetime may change.
Before initial use, check the last charging which is marked on the battery. If it is older than 9 months, replace the
battery.
Do not short-circuit the battery poles or power wires and always check correct battery polarity.
Mount the device onto a heavy-duty DIN-rail or screw it securely on a flat surface. Before mounting the unit on a flat
surface, detach the DIN-rail slider (remove the plastic lock mechanism by using a flat-blade screwdriver and move the
lock downwards while pushing the plastic slide upwards at the same time) and the two aluminum DIN-rail brackets
(Torx T10 screwdriver).
Do not install the battery module upside down.
Install the device in a cool area inside an enclosure providing protection against electrical, mechanical and fire hazards.
Ensure sufficient ventilation by following the requirements of the EN 50272-2.
The device is designed for pollution degree 2 areas in controlled environments. No condensation or frost allowed.
The enclosure of the device provides a degree of protection of IP00.

Do not use batteries other than the original batteries supplied by the manufacturer to avoid conflicts with agency
approvals.
The maximum surrounding air temperature is +50°C (+122°F). The operational temperature is the same as the ambient
or surrounding air temperature and is defined 2cm below the device. Charging is allowed up to +40°C.
Frequently charging below +5°C reduces the lifetime of the battery.
The device is designed to operate in areas between 5% and 95% relative humidity.

Batteries need to be replaced periodically. The time interval depends on the ambient temperature in which the battery
is used and on the number and depth of discharge cycles. In a typical application it is recommended to replace the
batteries at least every 2 years.
Disconnect battery fuse before replacing the battery.
Regarding disposal of used batteries see chapter 2.
Fig. 6-1 Replacing the battery
To replace battery:
1) Loosen screws (1) with only one turn.
(Use a flat-blade or Torx T20 screwdriver)
2) Slide the mounting bracket (2) sideways.
3) Tilt the mounting bracket to the front and
take it off.
4) Unplug the battery terminals.
5) Remove the battery.
6) 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.
