It is highly recommended to install an external fuse holder or a DC breaker to
disconnect the batteries before performing the batteries connection procedure.
Short-circuit current available in the battery terminals must not be higher
than 2000A to guarantee the safety of the equipment�
Always work with the battery cables disconnected
Follow these steps for proper connection of the battery to the inverter:
1�-
Select proper wire cross section. Recommended minimum cross section for 80A is 25mm

.
Select wire insulation type depending on installation environmental conditions (outdoor, humid-
ity, UV light…). In order to meet electromagnetic emissions regulations, wire should be shorter
than 3m.
2�-
Use M10 ring type terminal for the positive wire. Use M8 ring terminal for the negative wire.
Check that the ring terminal pass through the cable gland prior to crimping. Pass the cable
through the cable gland prior to crimping, if required.
