9. Installation
This product contains potentially dangerous voltages. It should only be installed under the supervision of a suitable qualified in-
staller with the appropriate training, and subject to local requirements. Please contact Victron Energy for further information or
necessary training
9.1. 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 batter-
ies.
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.
9.2. 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.

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.
9.3. Battery Connection Procedure
Proceed as follows to connect the battery cables:
