2.3. Other options
The wiring of these signals must be done with the mains disconnected from the charger.

2.3.1. External voltage sensor (see fig 5)
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 (0.75mm
•
• connect a black wire (0.75mm
check that the accompanying LED is lit, otherwise check cabling
•
2.3.2. External temperature sensor (see fig 5)
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 negative pole of the battery.
To connect the temperature sensor, proceed as follows:
connect the red wire to connector "+ Temperature sensor"
•
connect the black wire to connector "- Temperature sensor"
•
• mount the temperature sensor on the negative pole of the battery
• check that the accompanying LED is lit, otherwise check cabling
2.3.3. Remote on/off (see fig 5)
The wiring of the remote switch requires extra attention. Since this input is quite sensitive it is advised to use twisted wires for this
connection.
The remote on/off input can also be connected to an open collector optocoupler: the open circuit voltage is 3V and the closed circuit
current is 100 µA.
When no remote switch is connected the remote on/off terminals must be short circuited by a short wire.
The remote on/off input can be connected to a Lithium Battery Management System VE.Bus BMS ('charge disconnect' output)
with a Skylla-i remote on-off cable ASS030550400.
2.3.4. Alarm relay connections (see fig 5)
The alarm relay is active when the charger is charging normally, no error condition present and the battery voltage is within the
voltage range 23.7V and 33.6V. The relay is switched off when the charger stops, an error occurs or when the voltage drops below
23.45V or rises above 33.85V.
2.3.5. CAN bus connection (VE.Can)
The VE.Can connectors (RJ45) provide access for control (Skylla-i remote control panel, Color Control GX or NMEA 2000). The
two RJ45 connecters in each charger (see figure 7) are parallel connected. There is therefore no functional difference between
these connectors.
The end of a CAN cable should have a bus terminator. This is achieved by inserting a bus terminator in one of the two RJ45
connectors and the CAN cable in the other. In case of a node (two CAN cables, one in each RJ45 connector), no termination is
needed.
Several Skylla-i control panels can be connected to one charger or to a set of synchronised and parallel connected chargers.
A Lynx Ion can be connected to the Skylla-i charger directly via the VE.Can bus, the 'allow-to-charge' condition will be
communicated via the VE.Can bus automatically, no separate wiring is required.
