5.2 Charging of other batteries

DYNACORD battery modules DEM 316, DEM 317 or other maintenance - free 24V lead-acid batteries with a rated capacity up to 65 Ah can be charged with the charging unit DEM 313. To do so, the charging output CHARGE OUTPUT + (8) is to be connected with the plus pole and the charging output CHARGE OUTPUT - (8) with the negative pole of the battery respectively.

For temperature tracking of Ihe charging voltage in standby mode, the temperature sensor (retrofitting kit NRS 90200) must be installed according to the retrofitting instructions and is to be connected with the charging unit (see also Figures 1, 2 and Sections 3.1, 6.9).

In order to prevent exhaustive discharging of the battery, suitable relays must be used which are to be connected with the charging unit according to Figure 1 or Figure 2. The total coil resistance of the relays may not be below 70 ohms.

Attention: VDE 0510 is to be observed for the installation of the batteries. Short-circuit-proof installation of battery cables must be observed in particular, and precautions against the risk of explosion must be taken.

6. Description of function and operation

The charging unit DEM 313 is designed for constant I/U battery charging in continuous battery power supply mode. Primary switched circuit technology is used to generate a regulated charging voltage or charging current which has a high efficiency rate coupled with excellent regulation characteristics and good reliability.
