Designing Your Installation
Before doing anything else, you need to determine how you are going to
use your XPower Plus, 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 cable size for your XPower 1200 Plus or XPower 1750
Plus
• Select the correct fuses or circuit breakers
Study Figures “Configuration for Normal Loads” on page 3–2 and
“Configuration for Heavy Loads” on page 3–3 for an example of a setup
for normal or heavy loads in a vehicle. When you have decided upon your
configuration, then you can calculate battery requirements.
