Connecting the Battery Current Sensor:<br />
Use cables of intrinsically safe circuits<br />
Always use cables of intrinsically safe circuits for the connection of battery current sensors.<br />
"Intrinsically safe" means here that the cable is double-insulated and that the wire melts but<br />
the insulation remains intact in the event of a short circuit. In addition, the cable is not<br />
combustible. In order to avoid measuring errors, make sure to use twisted cables.<br />
Installation notice<br />
The battery current sensor must be looped around the negative pole of the battery. In<br />
addition, the contact of that battery current sensor, which is connected to the <strong>Sun</strong>ny Island<br />
(1), must be connected to the terminal "BatCur+" (see following figure).<br />
• Positive battery current means that the battery is discharging (current from the<br />
battery)<br />
• Negative battery current means that the battery is charging (current into the battery)<br />
1. Pierce a hole in the rubber connection area at the corresponding position.<br />
2. Starting from the outside, lead the insulated conductors with bootlace ferrules through the hole<br />
in the <strong>Sun</strong>ny Island.<br />
3. Connect the cables correspondingly to the "BatCur" connection of the 4-pole print terminal<br />
included in the delivery.<br />
4. Tighten the terminals.<br />
5. Insert the 4-pole print terminal into the "BatCur" socket on the <strong>Sun</strong>ny Island.<br />
☑ The battery current sensor is installed.<br />
