The JD connector is the supply connector: connect an uninterruptible power supply (usually
the engine starter battery) to the 1-GND terminal (minus) and to the 2-+BATT terminal (plus).
The minus terminal 1-GND is the reference and the common return of the digital inputs, of the
outputs and of the current and voltage measurements. It must be connected to the
protective earth. Systems requiring isolation between battery minus and protective earth are
nonetheless usable, but they may generate operating problems and could require special
precautions, such as the use of insulating voltage transformers for the auxiliary source and
the generator voltage (AC) measurements.
Although the device is protected by a built-in self-resetting fuse, it is recommended that you
use a fuse for the protection of the positive line
2-+BATT . of supply.
All the current delivered by the SSR outputs flows through the positive input 2-+BATT.,
therefore you need to pay attention to the dimensioning of the fuse.
The device automatically recognizes when it is powered if the generator set battery nominal
voltage is 12 or 24V for managing the related logics and alarms. The recognition also takes
place every time you switch to mode
OFF/RESET .
Notice: connect the positive voltage only after the connections are all established.
Before connecting the positive voltage, open all the panel.
