PRODUCT DESCRIPTION
The UZK24.262 battery module utilizes two or four non -spillable
maintenance-free VRLA lead-acidbatteries (connected inseries) that are
assembled in one package with all the required wiring included.
Connectorterminals for the paralleling of 2 batteries are included too.
The UZK24.262 comes with the sensor board UZW24.100 which contains
a temperature sensor, fuses for 2 to 4 batteries plus an auto-resett abl e
fuse which is suitablefor balancer currents upto 2.5A. This fuse protects
the center-tapwire between the battery module and the DC-UPS control
unit.
The sensor board enables to monitor and charge the two batteries
individuallyand precisely, extending the service life of the batteries an d
making matching of replacement batteries unnecessary. Usage o f t he
sensor board is optional, the DC-UPS will also function without the
sensor board installed.
The battery module is available in four different options. It can be
ordered as UZK-module with batteries or as UZO-module without
batteries,so these can be procured separately and installed at a l ater
date to avoid outdated batteries. Both modules contain the connecti on
board and wiring kit UZW24.100.
The extension kits can be ordered as UZK24.262-E1 withbatteries or as
UZO24.262-E1 without batteries for the paralleling of a second b at te ry
pack. Each module contain battery terminal covers and ring cable lugs.

1. INTENDED USE
This module is designed for installation in an enclosure and is intended for the general professional use such as in industrial control,
office, communication, and instrumentation equipment.
Do not use this module in equipment, where malfunction may cause severe personal injury or threaten human life.
2. 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 months, 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.
CAUTION: The unit contains wet cell batteries. Ventilation of the installation room in accordance with the rules of Canadian Electrical
Code, part 1 is required if used in Canada.
The battery module is for use in a controlled environment. Do not use the device in pollution degree 3 areas without additional
protection or in applications where a degree of protection better than IP00 is required.
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 as the air temperature 2cm below the device.
3. INSTRUCTIONS FOR BATTERY STORAGE
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 than charged
batteries.
Do not store batteries longer than 9 months without charging or performance and lifetime may change. Every 9 months or w henever
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.

4. INSTRUCTIONS FOR REPLACING BATTERIES
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 5.
Fig. 4-1 Replacing the battery
To replace battery:
ATTENTION! Disconnect battery fuse before replacing the battery.
1) Loosen screw of battery holder with only one turn.
Remove Insulating caps from the battery terminals.
2) Unscrew the battery terminals.
3) Slide the mounting bracket sideways and take the mounting
bracket off.
4) Remove the battery.
5) Insert the new battery.
6) Fix it again with the mounting bracket and make sure that
the lock washer lies between the screw head and mounting
bracket.
7) Screw the mounting bracket with tightening torque: 2Nm (18
lb.inch).
8) Do not over-tighten screws of the terminal bolts of the
battery. Recommended tightening torque: 2.5Nm (22
lb.inch)
9) Insert battery fuse
5. INSTRUCTIONS FOR DISPOSAL OF THE BATTERIES
Batteries must be completely discharged before replacement and can be returned to the supplier of the battery module or the battery
manufacturer for disposal.
Always dispose batteries through a recycling organization.

15.RECOMMENDATIONS FOR A LONG BATTERY LIFE
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 than 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.
