• Never install extra washers between the
terminal mounting surface and the battery
cable lug—the connection must be direct and
secure.
• Always install breakers or fuses within the
positive battery cable.

SYSTEM PROTECTION
An FX Series Inverter/Charger is part of an electrical system that protects:
• You
• The wires
• The components
• The devices served by the system
OutBack circuit breakers protect wiring by limiting
the amount of current entering a system. All
wired electrical systems require circuit breakers or
fuses for protection.
OutBack oers both breakers and fuses for over-
current protection. If they are provided by other
vendors, they must be properly rated.
Each FX must be part of a permanently grounded
electrical system (see page 7). Grounding protects
people and equipment from electrical shock.
Grounding must be done according to local and
national electrical codes.
