1-1. General Safety Precautions
•
•
•
Do not expose the inverter to water, mist, snow, spray, or dust.
To reduce risk of hazard, do not cover or obstruct the ventilation openings.
Do not install the inverter in a zero-clearance compartment. Overheating may occur.
•
•
To avoid risk of fire and electronic shock, be sure all DC and AC wiring is in good condition and not undersized.
Do not operate the inverter with damaged or substandard wiring.
•
•
This inverter contains components that can cause arcs and sparks.
To prevent fire or explosion do not locate flammable materials near the inverter.
1-2. Precautions When Working with Batteries
•
•
•
•
If battery acid contacts skin or clothing, wash it off with soap and water immediately. If battery acid contacts
your eyes, wash it out with cold running water for at least 20 minutes and get medical attention immediately.
Never smoke or create sparks or flame in the vicinity of the battery or the engine.
Do not drop a metal tool on the battery. The resulting spark or short circuit may cause the battery to explode.
Remove jewelry and personal metal items such as rings, bracelets, necklaces, and watches when working with
batteries. Jewelry may cause a short circuit creating very high temperatures which can melt metal items and
cause severe burns.

3-1-2. ON / OFF/ REMOTE (Main) Switch:
Before installing the inverter, be sure the main rocker switch is set to “OFF”.
Before using the remote, you need to ensure the main switch is in the “REMOTE” position.
3-1-3. AC Input Circuit Breaker:
The AC input circuit breaker protects the unit from overload. When an overload condition exists, the circuit
breaker will trip. To reset push the breaker switch, the unit will resume normal operation.
3-1-4. Remote Port: The modular jack labeled Remote Port is not used.
3-1-5. Remote Control Connector:
(The Remote Control Connector is enabled when the ON/OFF/Remote main rocker switch, 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.

3-1-9. AC Frequency Selection:
AC output frequency is selected by Dip Switch “S4”.
Important Note: 60Hz AC loads may be damaged if 50Hz is selected.
The unit must be turned OFF/ON to accept new dip switch settings.

3-1-10. 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 40W, a load greater than 40W is required to "keep the
inverter awake" to produce AC power. If the AC load falls below 40W 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.

Connect DC cables, battery positive (+) to inverter positive (red); battery negative (-) to inverter negative (black).
Be aware, there will be a large spark when the last DC connection is made. Be very careful to NEVER connect DC

4. Rear Panel Area:
4-1. Cooling Fan and Ventilation:
Maintain at least 2" clearance all around the inverter at all times.
5. Installation location:
Install the inverter in an environment that meets the following requirements:
5-1-1. Dry – Do not allow water to drip on or to get inside the inverter.
5-1-2. Cool – Ambient air temperature should be between 32°F and 105°F, the cooler the better.
5-1-3. Safe – Do not install the inverter in a battery compartment or other areas where flammable fumes may exist,
such as fuel storage areas.
5-1-4. Ventilation - Ventilation Openings on front and back are not to be obstructed.
5-1-5. Dust free – Do not install the Inverter in dusty environments. Dust will be drawn inside and will greatly
shorten the life of the inverter.
5-1-6. Close to batteries but not exposed to battery fumes – Use the recommended wire lengths and sizes (see DC
Wire and Fuse Sizes Chart). 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.

6. 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.

6.1. DC Connections:
When ready to connect DC cables, connect battery positive (+) to inverter positive then connect battery negative (-)
to inverter negative. Be aware, there will be a large spark when the last DC connection is made. This is
normal. Never connect inverter positive to battery negative. Be very careful to NEVER connect DC
terminals to the inverter backwards. Reverse polarity connection may cause permanent damage to the inverter.
Torque the DC terminal bolts to 9 -10 ft-lbs.
WARNING: Loose DC connections will overheat and cause a fire
WARNING: To protect the DC cables, and to protect the inverter if positive and negative are reversed, a DC fuse
must be installed in the positive inverter cable within 18” of the battery. Failure to place a fuse in the inverter positive
cable will void the warranty.

Please double check and review all connections to ensure the wires are in correct terminals and the connections
are tight. 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. Inverter Operation:
Use the ON/OFF/REMOTE main rocker switch on the front panel to turn the inverter ON.
8-1. 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-atime to prevent inverter overload due to the initial surge required to start the loads.
8-2. Set the rocker switch to the OFF position to turn the inverter OFF.
8-3. Set the rocker switch to the REMOTE position if a customer-supplied remote control switch is used with the
Remote Control Connector (See section 3-1-2.)
