Connection Of Battery Cables - Victron energy MultiPlus 12/3000/120-16 Manual Del Usuario

4. Installation
This product may only be installed by a qualified electrical engineer.
4.1 Location
The product must be installed in a dry and well-ventilated area, as close as possible to the batteries. There should be a clear space of at
least 10 cm around the appliance for cooling.
Excessively high ambient temperature will result in the following:
Reduced service life.
•
• Reduced charging current.
• Reduced peak capacity, or shutdown of the inverter.
Never position the appliance directly above the batteries.
The MultiPlus is suitable for wall mounting. For mounting purposes, a hook and two holes are provided at the back of the casing (see
appendix G). The device can be fitted either horizontally or vertically. For optimal cooling, vertical fitting is preferred.
The interior of the product must remain accessible after installation.
Try and keep the distance between the product and the battery to a minimum in order to minimize cable voltage losses.
For safety purposes, this product should be installed in a heat-resistant
environment. You should prevent the presence of e.g. chemicals, synthetic
components, curtains or other textiles, etc., in the immediate vicinity.

4.2 Connection of battery cables

In order to utilize the full capacity of the product, batteries with sufficient capacity and battery cables with sufficient cross section should
be used. See table.
Recommended battery capacity (Ah)
Recommended DC fuse
Recommended cross section (mm
per + and - connection terminal
0 – 5 m
5 – 10 m
* '2x' means two positive and two negative cables.
Remark: Internal resistance is the important factor when working with low capacity batteries. Please consult your supplier or the relevant
sections of our book "Energy Unlimited", downloadable from our website.
Procedure
Proceed as follows to connect the battery cables:
Use a torque wrench with insulated box spanner in order to avoid shorting the
battery.
Maximum torque: 12 Nm
Avoid shorting the battery cables.
Undo the four screws at the front of the enclosure and remove the front panel.
•
Connect the battery cables: see Appendix A.
•
• Tighten the nuts well for minimal contact resistance.
