4.1 ON / OFF/ REMOTE (Main) Rocker Switch:
Before installing the inverter, be sure the main rocker switch is set to “OFF”.
Use the ON/OFF/REMOTE main rocker switch on the front panel to turn the inverter ON.
Set the rocker switch to the ON position to turn the inverter ON. Notice the beeps and the activity of the indicator
light display. The Status led should be green indicating the inverter is ready to deliver AC power to the loads. If
multiple AC loads will be operated at the same time it may be necessary to turn the loads ON one-at-a-time to
prevent inverter overload due to the initial surge required to start the loads.
Set the rocker switch to the OFF position to turn the inverter OFF.
Set the rocker switch to the REMOTE position if a customer-supplied remote control switch is used with the
Remote Control Connector, located on the inverter back panel. (See section 3-8-2.)

4.4 AC Output Wiring Methods:
Three AC output wiring methods are provided.
• GFCI Protected Receptacle
• GFCI Protected Hardwired Output ( LOAD terminals on GFCI Receptacle )
• Non-GFCI Hardwired output via terminal strip inside receptacle compartment.
4.5 AC Output GFCI Duplex Receptacle
The AC output neutral conductor is connected to AC ground and inverter chassis ground inside the inverter. This
conforms to National Electrical Code requirements that separately derived AC sources (such as inverter and
generators) have their neutral conductors tied to ground in the same way that the neutral conductor from the utility
is tied to ground at the AC breaker panel.
Do not connect AC neutral to AC ground downstream of the GFCI. This would cause the GFCI to trip.
Never connect the inverter output to another AC power source such as a generator or utility power. The
inverter would be destroyed.

4.8 Load Demand (Power Saving Mode)
The Load Demand feature allows the inverter to "go to sleep" if the inverter is ON but no AC loads are present.
Load Demand is adjustable via Dip Switches S1, S2 and S3 on the front panel.
Example: With the Load Demand Threshold watt setting at 45W, a load greater than 45W is required to "keep the
inverter awake" to produce AC power. If the AC load falls below 45W the inverter will "go to sleep", entering Load
Demand power saving mode.
The unit must be turned OFF/ON to accept new dip switch settings.

6.2 Remote Control Connector
(
The Remote Control Connector is enabled when the ON/OFF/Remote main rocker switch, located on the front of
the inverter, is in the Remote position.) This three-position connector, Phoenix part number 1911868, is labeled
GND, ENBBAR, and ENB. Use this connector with a customer supplied SPST switch to provide remote ON/OFF
control of the inverter. Remote switch circuit arrangement options are +12v to ENB, or Battery Negative to
ENBBAR, or GND to ENBBAR. The most common application (+12v to ENB) uses a +12v hot-in-run from vehicle
fuse panel to turn inverter ON when vehicle is ON, and OFF when vehicle is OFF.

7 Installation
7.1 Inverter Installation Considerations
Install the inverter in an environment that meets the following requirements:
Mounting: Locate a flat secure, dry, horizontal surface large enough to mount the inverter.
Dry – Do not allow water to drip on or to get inside the inverter.
Cool – Ambient air temperature should be between 32°F and 105°F, the cooler the better.
Safe – Do not install the inverter in a battery compartment or other areas where flammable fumes may exist, such
as fuel storage areas.
Ventilated –Maintain at least 3" clearance all around inverter. Be sure ventilation openings on front and back are
not obstructed.
Dust free– Do not install the Inverter in dusty environments. Dust will be drawn inside and will greatly shorten the
life of the inverter.
Close to batteries but not exposed to battery fumes – Use the recommended wire lengths and sizes (see section
3-5). Avoid excessive cable lengths. Do not install the Inverter in a non-vented compartment with the batteries.
Do not mount the Inverter where it will be exposed to the gases produced by the batteries. Battery gases are very
corrosive. Prolonged exposure will damage the Inverter.
7.2 DC Wiring Considerations
• Do not connect the 12V model to a 24V battery. The unit will be destroyed immediately. Operation of
the inverter without a proper ground connection may result an electrical safety hazard. Damage caused by
reversed polarity will void warranty.
•
WARNING! Loose DC connections will overheat and could cause a fire.
Torque the DC terminal bolts to 9 -12 ft-lbs.
WARNING! Shock Hazard.
Before proceeding further, verify that the Inverter is NOT
connected to batteries, and that all wiring is disconnected from any
electrical sources.
NEVER connect the inverter AC output terminals to an incoming
AC source.

Owner’s Manual
VLT Series 2000/3000 Watt True Sine Wave Inverter Owner's Manual Page 14
A DC FUSE IS REQUIRED to protect the DC cables in case of a short circuit. The wiring of the inverter
installation should conform to the National Electric Code (NEC) and any other state or local codes in effect at
the time of installation. Article 551 of the NEC requires any DC cable from a battery, which measures longer
than 18 inches along its length, be protected by a fuse.
Failure to place a fuse in the inverter
positive cable will void warranty.
• BE AWARE, as a large number of capacitors become charged upon completion of the DC circuit,
THERE WILL BE A LARGE SPARK when the last battery connection is made. The spark is normal and will
occur every time the batteries are connected. It is advisable to make the last DC connection at the inverter,
not at the battery, to reduce the risk of battery explosion.
• To minimize electromagnetic radiation that could interfere with sensitive electronics, route the AC output
wiring and DC power wiring with as much physical separation as possible from low voltage wiring such as
audio and video signal wires. Route the DC positive and negative cables as close together as possible and
use cable ties to keep them together.
• If passing through steel or other ferrous metal walls, the DC input cables need to pass through the same hole
to prevent causing a transformer effect. If two holes are required, cut a slot to connect the two holes to
prevent heating of the ferrous metal.
• Proper DC cable size is critical for the performance and safe operation of the inverter system. The
DC Cable and Fuse Sizing Chart shows the minimum cable sizes recommended. These sizes allow a ½ volt
maximum voltage drop at maximum inverter capacity and will insure optimum inverter performance. DC cable
to be used with these fuse sizes should be minimum insulation temperature rating of 105°C and voltage
rating of 600V.
• DC cables should be as short as possible.
• Do not use the vehicle chassis as the DC negative conductor. The negative cable should be the same size as
the DC positive cable and should be connected directly to the battery negative terminal.
7.3 DC Wire and Fuse Sizes:
Use the following DC cable and inline fuse sizes. DC cables should be as short as possible (ideally less than 10
feet, never exceeding 20') and large enough to handle the required current in accordance with the electrical codes
or regulations applicable to the installation. DC cables that are too small or too long will cause DC voltage drop
which will result in deteriorated inverter performance such as poor surge capability and frequent low-input voltage
warnings and shutdowns.

8 AC Wiring Considerations
8.1 AC Neutral Bonding
The neutral conductor of the inverter AC output circuit is connected to ground (the bare wire) inside the inverter.
This conforms to National Electrical Code requirements that separately derived AC sources (such as inverters
and generators) must have their neutral conductors tied to ground. The AC output ground wire should go to the
grounding point for the AC loads; for example, if there is a distribution panel ground bus. Do not connect neutral
to ground in any panel, receptacle or device downstream of a GFCI as this would cause the GFCI to trip.
8.2 GFCI Receptacles
While the pure sine wave output of the Inverter is equivalent to the waveform provided by utilities, it is possible
that some GFCI's may not perform properly on inverter power. If additional GFCI receptacles are needed use
Hubbell GFR5252WA or Pass & Seymour 2091 or 2094.
9 Troubleshooting
WARNING!
Do not open or disassemble the Inverter. Attempting to service the unit
yourself may result in a risk of electrical shock or fire, and will void warranty.
