Remark: Internal resistance is the important factor when working with low capacity batteries.
Please consult your supplier or the relevant sections of our book “electricity on board”,
downloadable from our website.
Procedure
Proceed as follows to connect the battery cables:
Use an insulated box spanner in order to avoid shorting the battery.
Avoid shorting the battery cables.
Connect the battery cables: the + (red) and the - (black), to the battery see appendix A.
Reverse polarity connection (+ to – and – to +) will cause damage to the product.
Secure the nuts tightly in order to reduce the contact resistance as much as possible.
4.3 DC safety fuse
There is no safety fuse inside the inverter; this should be installed externally. The
recommended safety fuses can be found in the table below
