Page 5: Utilization
The output voltage of the internal power supply is present at the DIRECT OUT (9) connector. With the DPP 4004 this connector’s maximum power handling capacity is 4 A; the DPP 4012 provides 12 A. The output offers internal short-circuit protection and it can be operated without load. It also serves to use the appliance as plain power supply –... - Page 6 The output MODULES OUT (14) is meant for the connection of devices (relay-fi elds, alarm-devices, voice reproduction, etc.) that can be switched off during a power outage – during which time the PA- system should operate in the stand-by mode. Switching off unnecessary devices during the occurrence of a power failure is preferable, otherwise the battery is unnecessarily strained.
