caution!
1. The metal chassis of the inverter and the Grounding Terminal of the NEMA5-15R outlet(s)
are internally bonded (connected) to the Negative DC Input Terminal on the inverter. In a
vehicle / boat, the Negative Terminal of the battery is bonded to vehicle chassis / boat’s hull.
Hence, the metal chassis of the inverter and the AC loads will be automatically grounded
(bonded to the vehicle chassis / boat’s hull).
2. Please ensure that the Negative DC Input Terminal on the inverter or the Battery Negative
Terminal on the battery itself is bonded to Earth Ground WHEN THE INVERTER IS USED ON
LAND.
3. The Line and Neutral Terminals of the NEMA5-15R AC outlets are isolated from its Ground-
ing Terminal. Thus, the metal chassis of the AC loads and the metal chassis of the inverter
will also be isolated from the Line and Neutral. The Grounding Terminal of the AC outlet
is connected to the input section of the Electronic Ground Fault Protection Circuit on the
Power Circuit Board. Due to the above implementation, the voltage on the Neutral and Line
Terminals of the AC outlet with respect to the chassis of the inverter / chassis of the AC loads
will be pulsing DC voltage with average DC value of up to 50V (will read 75 VAC on AC scale
of the Voltmeter because of pulsing nature of DC voltage). Do not toucH tHe neutraL
terminaL / neutraL conDuctorS!
4. Do not connect to AC distribution wiring where the Neutral is bonded to Ground. The
inverter will see this as abnormal condition of Ground Fault and will shut down.
5. Do not use with Positive Grounded Electrical Systems (the majority of modern automobiles,
RVs, trucks and boats use Negative Grounded Electrical Systems).
6. Observe correct polarity when connecting the DC input terminals of the inverter to the
battery. Connect Positive of the battery to the Positive input connector of the inverter and
the Negative of the battery to the Negative input terminal of the inverter. reverse polarity
connection will result in a blown fuse and may cause permanent damage to the inverter.
Damage due to reverse polarity is not covered under warranty.
7. This inverter will not operate high wattage appliances that exceed the output power limit
or the surge power limit.
8. Do not operate this inverter if it is wet.
9. Do not install in engine compartment – please install in a well-ventilated area.
10. This inverter is not tested for use with medical devices.
