The Skylla-i powers the VE.Can network with 12 V DC. Note that its connection is rated for a maximum voltage of 30 V DC: to
connect the Skylla-i to a VE.Can network that also contains devices connected to a 48 V battery bank, a special RJ45 cable
must be made and used which has pin 2 and pin 6 (NET-S / V+) not connected. This will connect GND, CAN-H and CAN-L, but
not the power line.
The two RJ45 sockets in each charger (see figure 7) are parallel connected. There is therefore no functional difference between
each of the sockets.
2.3.6. Synchronised parallel operation
Several chargers can be synchronised with the CAN interface. This is achieved by simply interconnecting the chargers with
RJ45 UTP cables (bus terminators needed, see section 2.3.5).
The paralleled chargers must have identical DIP switch and rotary switch settings.
A mix of Skylla-i 100 A and 80 A chargers can be paralleled.
Two output and three output chargers cannot be paralleled with each other.
The shore current limit of the parallel charger group can be set with the Skylla-i control panel. The current limit as shown on the
panel is the shore current of the group.
The output current of one charger may differ from another charger although connected in parallel.
If one charger from the parallel connected chargers is disconnected, the failure LED will blink on all units that used to operate in
parallel mode. To resolve this issue either reconnect the missing charger or power cycle the remaining units.
In case of using remote sensors (voltage and/or temperature), the remote sensor needs to be connected to one of the parallel
operating chargers. All other chargers will share the information via the CAN interface. The green LED in the charger with the
sensor connected to it, will be lit continuously, the other chargers will blink the corresponding LED.
In case of synchronized parallel operation the LED "ON" will blink every 3 seconds on all paralleled units.
2.3.7 Connecting the AC supply (see fig 6)
1. Check if the battery is connected to the charger.
2. Remove the front of the battery charger to access the AC input connector.
3. Connect the mains PE cable (green/yellow) to the AC input connector, terminal PE, located on the circuit board, see Figure
4. Connect the mains neutral cable (blue) to the AC input connector terminal N.
5. Connect the mains line cable (brown) to the AC input connector terminal L.
6. Select the correct battery charge curve before applying AC power (see section 3).
