5. INSTALLATION
Wall or floor mount the Skylla 24/100 3-phase charger in a dry, well ventilated area. Excessively high ambient
temperatures may adversely affect the output current and the lifetime of the charger. Best results are obtained in such
conditions if the charger is wall mounted. For secure placement, the Skylla 24/100 3-phase is supplied with mounting
holes both in the rear and in the underside. See drawing SK07002E.
Make sure the front panel can be reached after installation. The Skylla 24/100 3-phase charger and the battery's should
be place close together to keep the battery cables as short as possible, ensuring optimal loading.
The Victron Skylla 24/100 3-phase charger should be installed with the help of the following equipment:
a four core mains cable for connection, the core cross section should be 2,5 mm
two battery cables (max. length 6 meters, with clamps)
a screwdriver (no. 3) to remove the front panel and to connect the mains cables
a 12 mm wrench to connect the battery cables
By unscrewing the four front screws the front panel can be removed.
This way the charger internals are exposed for connection. All
connections are located at the bottom of the charger. Cables can be
fed through the holes in the bottom of the casing.
Victron battery chargers are designed to charge batteries; the
charger always expects the load of a battery and it is not a power
supply. Connect the battery before switching the charger on and
switch the charger off before the battery is disconnected.
5.1 Connecting earth
The Skylla 24/100 3-phase charger is not a double insulated charger.
The PE terminal must be connected to a true earth under all
conditions. See illustration 5. On a boat, the earth terminal on the
under side of the housing must be connected to the ground plate or
the hull. The shore connection must be earthed to the PE terminal on
the mains input connection block. For mobile applications (car,
caravan etc.) earth terminal must be connected to the metal chassis.
High earth leakage current.
Earth connection essential before connecting supply.
5.2 Connecting mains
Use a four core approved cable to connect the Skylla 24/100 3-phase charger to the mains. Remember that the PE
terminal must always be earthed.
5.3 Connecting the battery
It is important that the connections between the charger and the battery are made in such a way that power loss is
minimised. The cables must be as short and as thick as possible to reduce resistance. We recommend the following
minimum copper cross section for these battery cables. Cable lengths in excess of 6 meters are not recommended.
