caution!
• Please ensure that the recommended external fuse specified in Table 4.2 above
(fuse is not supplied) is installed in series with the positive cable and is as close to
the Battery (+) terminal as possible (preferably within 7”).
• Please ensure that all the connections are tight. Loose connections may cause
overheated wires and melted insulation.

General information
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 vehiclchassis / 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. 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
