UZK12.071 Installation Manual
EN
Product Description
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battery or as UZO-module without a battery which can be installed at a later date to avoid outdated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.
Intended Use
This device is designed for installation in an enclosure and is intended for commercial use, such as in
industrial control, process control, monitoring and measurement equipment or the like. Do not use this
device in equipment where malfunction may cause severe personal injury or threaten human life.
Installation Instructions
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 month,
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.
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.
Instructions for replacement and disposal of 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 batteries.
Always dispose batteries through a recycling organization. Optionally, batteries can be returned to the
supplier or the battery manufacturer. Batteries must be completely discharged before recycling.
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.
Installation Instructions for Hazardous Location Areas
The device is suitable for use in Class I Division 2 Groups A, B, C, D locations and for use in Group II
Category 3 (Zone 2) environments.
Hazardous Location classification: ATEX: EPS 15 ATEX 1 025 X, II 3G EX ec IIC T4 Gc
WARNING EXPLOSION HAZARDS!
Substitution of components may impair suitability for this environment.
Do not disconnect the unit or remove or insert the fuse or battery unless power has been switched off
or the area is known to be non-hazardous.
A suitable enclosure must be provided for the end product which has a minimum protection of IP23
and fulfils the requirements of the EN 60079-0. Sufficient ventilation must be ensured in the final
installation.
Do not use batteries other than the original batteries supplied by the manufacturer or batteries, which
are approved according to EN/ IEC 60079-7.
