1. Application

The charging unit DEM 313 was especially designed for fully automatic charging and monitoring of batteries in the emergency power supplies of alarm devices. In conjunction with the battery modules DEM 316 with 38 Ah or DEM 317 with 65 Ah rated capacity, this combination results in a reliable and failsafe emergency power source for continuous battery power supply operation. The integrated monitoring module ensures permanent battery monitoring.

2. Installation instructions

The airflow of the unit must not be blocked. The appliance must be protected against:

-drip or splashwater

-direct sun irradiation

-high ambient temperature or direct influence of heat sources

-high air humidity

-heavy dust deposits

-strong vibrations

lf ihe unit is brought directly from a cold to a warm place, dampness can precipitate on the inner parts. The unit may only be put into operation after it has warmed up to the ambient temperature (approx. after one hour).

Should an object or liquid get into the case, disconnect the unit from the current sources immediately and have the device checked by a DYNACORD service center, before further use.

Do not use any sprays to clean the unit, as these can damage it, perhaps causing it to ignite suddenly.

3. Before commissioning

Before connecting the unit to the mains, the following connections must be made:

∙The D-sub connector socket BATTERY CONTROL (9) of the charging unit ist to be connected with the D-sub connector BATTERY CONTROL of the battery module (also see Figure 1 and Section 3.1).

∙The CHARGE OUTPUT (8) of the charging unit is to be connected with the charging input CHARGE

CURRENT of the battery module. Please observe correct polarity (see Figure 1). The cross-section of the line between the charging unit and the battery module must be at least 2.5mm2. Insulated AMP flat-pin sleeves 6.3x0.8 mm must be used for the connections. The line length must not exceed 2 m.

∙Another device can be connected at the mains connector MAINS OUTPUT (5), if its power consumption does not exceed 4 A. The mains connector MAINS OUTPUT (5) is protected against overloading by a fuse (4) with the rating T4A. A fuse rating above T4A is not admissible.

∙lf all connections have been made correctly, the unit can be connected with the mains by means of the supplied power cable. The mains cable is connected at the 3-pole mains connector socket (7) on the unit

Attention: The unit is wired to 2 30V AC by the factory. Switching over to 115 V AC is possible via wire jumpers inside the unit, (see Section 4).
