3 Installation
Chapter 3 provides information on cables and fuses to help you plan for
your installation, and provides procedures for installing the XM Series
Inverter.
Xantrex strongly recommends that you read the entire chapter before
starting to install the XM Series Inverter, so that you can plan an
installation that is suited to your power needs.
Designing Your Installation
Before doing anything else, you need to determine how you are going to
use your XM Series Inverter, and then design a power system that will
give you maximum performance. The more thorough your planning, the
better your power needs will be met. In particular, you will need to:
• Be aware of installation codes
• Calculate your battery requirements
• Choose an effective charging system
• Choose an appropriate location
• Calculate the DC and AC cable sizes
• Select the correct fuses or circuit breakers.
Study Figure 3-1, “DC Input Configuration for Normal Loads” on page
3–2 and Figure 3-2, “DC Input Configuration for Heavy Loads” on page
3–3 for an examples of a setup for normal or heavy loads in a vehicle.
When you have decided upon your configuration, then you can calculate
battery requirements.
