Battery connection
For optimal performance, use batteries with a suitable capacity and cables with sufficient cross-section, as indicated in the below table:
Inverter/charger | Recommended battery capacity (Ah) | Recommended cable cross-section (mm²) For cables between 1.5 and 5m |
|---|---|---|
12/500/20 | 60 - 300 | 16 |
12/1200/50 | 150 - 700 | 35 |
Warning
Use an insulated box spanner in order to avoid shorting the battery terminals.
Avoid shorting the battery cables.
Confirm battery cable polarity before connection. A reverse polarity connection will cause damage to the product (the safety fuse inside the Multi can be damaged).
Connect battery cables to the Multi and the battery, see the Connection overview chapter. Use a PZ 2 screwdriver for the 500VA unit and a flat screwdriver 6.5mm for the 1200VA unit.

All servicing must be undertaken by qualified personnel.
