8. Installation
This product contains potentially dangerous voltages. It should only be installed under the supervision of a suitable
qualified installer with the appropriate training, and subject to local requirements. Please contact Victron Energy for
further information or necessary training
8.1 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 product for cooling.
WARNING:
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.
This product 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.
WARNING: 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.
8.2 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 (mm²) per + and - connection terminal
0 – 5 m
5 – 10 m
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.
8.3 Battery Connection Procedure
Proceed as follows to connect the battery cables:
WARNING: Use a torque wrench with insulated box spanner in order to avoid shorting the battery.
Maximum torque: 14 Nm Avoid shorting the battery cables.
WARNING: Specific care and attention must be taken when making the battery connections. Correct polarity must be
confirmed with a multimeter before connection. Connecting a battery with incorrect polarity will destroy the device and is
not covered by warranty.
•
Undo the two screws at the bottom of the enclosure and remove the service panel.
•
Connect the battery cables. First the - cable then the +. Be aware that there may be a spark when making the
battery connections.
•
Tighten the nuts to the prescribed torques for minimal contact resistance.
