PLUS UZK24.122 Battery Module Installation Guide

Read this first

Before operating this device, please read this manual thoroughly and retain this manual for future reference! This device may only be installed and put into operation by qualified personnel. If damage or malfunction should occur during operation, immediately turn power off and send device to the factory for inspection. The device does not contain serviceable parts.
The information presented in this document is believed to be accurate and reliable and may change without notice. For any clarifications the English translation will be used

WARNING Risk of electrical shock, fire, personal injury, or death:

Turn power off before working on the device. Protect against inadvertent re-powering.
Do not open, modify or repair the device.
Use caution to prevent any foreign objects from entering the housing.
Do not use in wet locations or in areas where moisture or condensation can be expected.
Do not touch during power-on and immediately after power-off. Hot surfaces may cause burns

Product Description

The UZK24.122 battery module utilizes two non-spill able maintenance-free VRLA lead-acid batteries, which are 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ordered as UZK-module with a battery or as UZO-module without a battery which can be installed at a later date to avoid outdated batteries.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 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, which extends the service life of the batteries and makes the use of matched replacement batteries unnecessary. The use of the sensor board is optional, the DC-UPS will also function without the sensor board installed.

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 25.2V, the battery module should be charged. Apply a charging voltage of 27.6V (at 25°C) for 72 hours. Batteries with an OCV
below 24V should be disposed.
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.
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.
Shorten the length of the (+) and (-) wires as needed between the battery module and the DC-UPS. If separate wires are used, do not use wires smaller than 6mm2 (AWG 10). Do not use individual wires
longer than 2m (7ft) to avoid voltage drops on this connection.
Connect the sensor board signals to the DC-UPS by using control wires with a minimum wire size of 0.5mm2
(AWG 20) and the center tap with a minimum wire size of 1mm2 (AWG 16).

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.
