2.3. Connecting the starter battery
The Skylla-IP44 is NOT protected against reverse polarity of the starter battery.
("+" connected to "-" and "-" connected to "+").
Follow the installation procedure. The warranty expires when the Skylla-IP44 becomes
defective due to reverse polarity.
Disconnect the mains supply before making or breaking connections to the starter battery.
The starter battery has to be connected using wire of at least 1.5 mm
Connect the positive (+) battery-pole to the "Starter battery plus" connector, see Figure 1.
The negative pole of the starter battery has to be connected to the "-BAT" connection of the charger.
Note:
The starter battery can draw current from the battery connected to the main battery terminals in case the voltage of the starter battery
is lower than the voltage main battery. However, the main battery cannot draw current from the starter battery even when the starter
battery is fully charged and the main battery is at minimum charge level.
2.4. VE.Can bus connection
The two VE.Can bus connectors provide access for control with the Skylla-i control panel or NMEA 2000.
2.5. User relay, external sense and remote shut down
The wiring of these signals must be done with the mains disconnected from the charger.

2.5.1. External voltage sense
External voltage sensing may be used when accurate battery voltage sensing is important, such as high charging currents in
combination with long cables.
To connect the external voltage sensing option, proceed as follows:
- connect a red wire (0.75 mm
- connect a black wire (0.75 mm
2.5.2. External temperature sense
The external temperature sensor, supplied with the charger, can be connected to these terminals in order to perform temperature
compensated charging of the battery. The sensor is electrically isolated and must be connected to the positive or negative pole of
the battery.
