Page 11: Battery Selection
EN 54-4 also defines the Imax_b current as the maximum, short-term current that can be drawn when the battery bank is not required to be charged. For ZDSO500-DR2 and ZDSO500-DR3 PSUs, these will be outputs at all, i.e. 15A and 2× 15A respectively (see the maximum currents that can be drawn from the section. - Page 12 In ZDSO500-DR PSUs, the Aux outputs are used for this purpose. The load level can vary from a fraction to tens of amperes (maximum 15A for ZDSO500-DR2 PSU and 30A for ZDSO500- DR3 PSU).
- Page 13 Operating manual for ZDSO500-DR2 and -DR3 Doc. no. 0862.00.95-02.0 Page: 13/22 Attention. The battery bank working together must be of the same type, same capacity and same state (degree of charge). Example. In the VAS, due to the number of power supply outputs for the acoustic power amplifiers, ZDSO500- DR2 PSU is envisaged.
- Page 14 A brief description of the meaning of each switch position is provided next to the switch. The minimum capacity size is 100Ah for ZDSO500-DR2 PSU and 200Ah for ZDSO500-DR3 PSU, which by means of the next two sliders: 1. and 2. can be enlarged. The resulting capacity is the sum of the minimum volume and the values assigned to individual sliders set to the ON (raised) position.

The use of guides to support the cassette is required, however, these must not cover the ventilation openings located on either side of the cassette (at least 8 cm ventilation space must be provided). - Page 16 Each Aux output is fitted with its own safety fuse. These outputs are grouped into sets (Aux1..Aux4 for the ZDSO500-DR2 PSU and Aux1...Aux4 and Aux5...Aux8 for the ZDSO500-DR3 PSU). Each set has an additional common fuse that limits the total current that can be drawn from that set (see...

Therefore, a suitable fuse should be fitted in the immediate vicinity of the positive pole of the battery bank to protect against the effects of a possible short circuit (see Fig.3...
