reversed. However, the WF-5318 and WF-5320 will survive that; the inverter simply will not
operate. When the polarity is corrected, the inverter will function normally.
Ac Circuit Breaker
The ac output circuit is protected by a 30-amp auto-resettable circuit breaker. If excessive
current is drawn at the output (including when in pass-through mode), the breaker may open
the circuit. If that happens, the circuit breaker will automatically reset within one minute.
MAINTENANCE
To ensure years of reliable performance, it’s a good idea to periodically check the following:
• Make sure the inverter is clean. Turn o all sources of ac power including the inverter, and
then clean the exterior of the inverter with a slightly-damp cloth to prevent accumulation of dust
and dirt.
• Make sure the vents and fan openings are not clogged.
• Inspect the wiring and terminations; make sure the connections are tight and all wiring and
insulation is in good condition. Check for any discoloration of conductors or insulation, melted
plastic, or other sign of heat. Evidence of excessive heat usually indicates a loose or corroded
connection; this needs to be corrected immediately.
