PASSIVE BATTERY MODULE 24V, 7Ah Battery Capacity (2x 12V Batteries in Series) IP00 Open Type Protection Level Small Mounting Footprint ATO Fuse for Power Wires Included 2m Power Leads Included PT1000 Sensor for Battery Module Temperature Included Center-tap Terminal with Auto-resettable Fuse Included to Support the PULS 1-Battery-Concept The UZK24.071 passive battery module utilizes two nonspillable maintenance-free lead-acid batteries (connected in series), that are assembled in one package with all the required wiring included. Battery type Battery design life Battery voltage Battery capacity Battery current The battery module includes the monitoring and protection board UZS24.100. This board contains a temperature sensor and a center-tap connection with an auto-resettable fuse to protect the center-tap wire between the battery module and the DC-UPS control unit. Connecting the center-tap wire to the DC-UPS control unit enables all the benefits of the PULS 1Battery-Concept. This makes the use of matched replacement batteries unnecessary and allows a precise battery charging and testing which results in the longest possible battery life. Battery fuse Temperature sensor Charging voltage Self-discharge rate Temperature range The UZK24 battery module is available in two different options. It can be ordered with assembled batteries or as a battery bracket without batteries, allowing for different battery options. The mounting bracket option also allows the batteries to be assembled just in time, avoiding outdated batteries due to limited shelf life.

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. 6. INSTRUCTIONS FOR DISPOSAL OF THE BATTERY Always...

8. INSTALLATION INSTRUCTIONS This device may only be installed and put into operation by qualified personnel. Check the last charging date of the batteries (marked on the battery). If it is older than 9 month replace the batteries. PULS charges every battery before shipment. For storage, installation and operation, the requirements of the EN 50272-2 as well as other national regulations must be observed. Place the battery module in a cool area inside a cabinet and ensure sufficient ventilation for the battery. The battery module should be securely mounted on a flat surface. If damage or malfunction...

9. REPLACING BATTERIES Disconnect battery fuse before replacing the batteries. To replace battery, loosen screw with only one turn and slide the mounting bracket sideways. Replace only one battery at a time. Always dispose the batteries through a recycling organization. Batteries must be completely discharged before recycling. Batteries can also be returned to PULS or the battery manufacturer. Battery replacements can be acquired through PULS. PULS also offers a list with recommended batteries in case batteries need to be acquired elsewhere. 10. FUNCTIONAL DIAGRAM Fig. 10-1 Functional diagram...

12. UZS24.100 SENSOR BOARD The battery module includes the monitoring and protection board UZS24.100. This board contains a temperature sensor and a centertap connection with an auto-resettable fuse to protect the center-tap wire between the battery module and the DC-UPS control unit. The UZS24.100 is compatible with most of the PULS DC-UPS control units and enables all the benefits of the PULS 1-Battery-Concept.This makes the use of matched replacement batteries unnecessary and allows a precise battery charging and testing which results in the longest possible battery life.

16. 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! Fig. 16-1 Service life vs. ambient temperature, typ.
