Torque Requirements
Torque all AC wiring connections to 16 inch pounds. Torque DC cable connections
to 10-12 foot pounds.
AC Main Panel
If the installation will be powering a wide-range of appliances throughout the
vehicle, an AC main panel is often recommended. This is similar in appearance and
function as your homes circuit breaker panel, providing an additional level of control
and protection for the various circuits. Always refer to electrical codes for safe wiring
practices.
Circuit Protection
If using a AC main panel for distribution, always use breakers that provide the
correct ampere branch circuit protection in accordance with the National Electric
Code. The breakers must also be properly rated for the appliances that will be
powered.
NOTE: Both AC and DC disconnects / overcurrent protection must be provided as part
of the installation.
Wire Routing
Determine all wire routes throughout the vehicle both to and from the inverter.
Conductors that are at risk to physical damage must be protected by conduit, tape,
or placed in a raceway. Conductors passing through walls, bulkheads or other struc-
tural members must be protected to minimize insulation damage such as chafing.
During the installation, always avoid placing conductors near sources of chafing
caused by vibration or constant rubbing.
CAUTION: Always check for existing electrical, plumbing or other areas of
potential damage prior to making cuts in structural surfaces,
bulkheads or walls.
Typical routing scenarios are:
AC Input wiring from the shore power source to the inverter
AC Input wiring from a generator (optional) to the inverter
DC Input wiring from the batteries to the inverter
AC Output wiring from the inverter to the coachs AC main panel or to dedicated
circuits
Battery Temperature Sensor cable (optional) from the inverter to the batteries
Remote Control cable (optional) to the inverter
Ground wiring from the inverter to an external vehicle ground
