SECTION 4 | Installation
The Grounding Terminal of the NEMA5-15R AC outlet will be 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
NEMA5-15R AC outlet with respect to the chassis of the inverter / chassis of the AC loads
will be a pulsing DC voltage with average DC value of up to 50V (will falsely read 75 VAC
on AC scale of the Voltmeter because of pulsing nature of DC voltage). DO NOT TOUCH THE
NEUTRAL TERMINAL / NEUTRAL CONDUCTORS!
5. Do not connect AC output from the NEMA5-15 outlets 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.
DC Side Connections
General Information
1. Ensure that the unit is connected to 12V battery system. CONNECTION TO 24V BATTERY
SYSTEM WILL DAMAGE THE UNIT.
2. Donotuseadditionalexternalchargingsourcetochargethebatteryatvoltage>15.5V.
3. Do not use with Positive Grounded Electrical Systems (the majority of modern automobiles,
RVs, trucks and boats use Negative Grounded Electrical Systems).
4. Observe correct polarity when connecting the DC input terminals of the unit to the battery.
Connect Positive of the battery to the Positive input connector of the unit and the Nega-
tive of the battery to the Negative input terminal of the unit. Reverse polarity connection
will result in a blown fuse and may cause permanent damage to the unit. Damage due to
reverse polarity is not covered under warranty.
Requirements of DC Input Power Source
Approx. DC Input Current required by Inverter = Power consumed by the AC Load
in Watts ÷ 10.
DC current drawn from the battery when delivering the rated power of 1500W is 150A.
12 VDC input to the inverter should be fed from a 12V Battery System or from a 12.5 VDC
to 15 VDC Regulated DC Power Supply. If a DC Power Supply is used, its output current ca-
pacityshouldbemorethan2timesthemaximumDCinputcurrentdrawnbytheinverter.
Further explanation of operation is based on DC input power from a 12V battery. It is
recommended that Deep Cycle Type Batteries are used. For detailed technical information

Alternators” at www.samlexamerica.com under Support/White Papers.
DC Input Power Terminals
Custom made DC input terminals using M9 Nut / Bolt arrangement have been provided
for connecting DC input cables (11, 12 in Fig 3.1). The terminals are protected by plastic
covers.
