1. GENERAL
1.01 Dimensions inverters have been designed
and manufactured for many user applications and
long life. They utilize patented construction meth-
ods and high technology electronic parts and
circuitry.
1.02
CAUTION: Inverters produce hazardous
voltages,toavoid riskof harmor firethe unitmust
beproperlyinstalled.Therearenouserserviceable
parts inside, do not remove the cover.
CAUTION: The inverter should not be mounted in
a location that may be exposed to rain or spray.
CAUTION: The inverter should not be installed in
a zero clearance enclosure.
CAUTION: Damage to the inverter will occur if
correct polarity is not observed when installing the
DC input cables.
CAUTION: Damage to the inverter will occur if an
externalACpowersourceisappliedtotheinverter’s
AC output or its hardwire output.
CAUTION: The inverter contains a circuit breaker
and capacitor that may produce a spark. Do not
mount in a confined battery or gas compartment.
CAUTION: Working in the vicinity of lead-acid
batteriesisdangerous.Batteriesgenerateexplo-
sive gases during operation. There is a risk of
acidexposure.Thereisalsoariskofhigh current
discharge from shorting the battery that can
causefireand explosion.
CAUTION: Besuretheinverter's circuitbreaker
or fuse are turned"OFF" during installation.
2. DESCRIPTION
2.01The inverterconverts24VDCto120VAC,
60 HZ or 120/240 VAC ("D" option only) having
a quasi-sine wave form.
2.02Theinverterhas internalprotectionagainst
output short circuit, output overload and high
temperature conditions. Also, there is a
thermallycontrolledcoolingfan.
2.03 The inverter is designed to operate any
120 VAC, 60 Hz or 120/240 VAC, 60 HZ ("D"
option only) single phase appliance, equipment
or tool within its power ratings, unless the
equipment is specifically designed to operate
from a pure sine waveform.
2.04 The inverter has a heavy duty printed
circuit board coating ("Q" feature).

3. INSTALLATION
3.01The following instructions should be thor-
oughly read and understood before installation.
3.02 CAUTION: Invertersproducehazardous
voltages, to avoid risk of harm or fire the unit
mustbeproperlyinstalled.
CAUTION: Damage to the inverter will occur if

IMPORTANT NOTE FOR VEHICLE
INSTALLATION:
Do not use the vehicle
chassis as the negative return in place of a return
cable. Use the same size cable as the positive
connectionand rundirectly tothe battery/alterna-
tor.
3.05.4Install the wiresat the battery,inverter
and then fuse holder. Make sure that good, clean
connections are made. Use care not to touch the
positiveandnegativewirestogether. Thiswillresult
in a violent spark and could result in exploding
batteriesandfire.
3.05.5
CAUTION: Connecting the inverter in-
correctly to the battery will cause damage that is
notcoveredunderwarranty.
3.05.6Thebatteryinputterminalsarelocatedin
the wiring compartment. A mounting spark may
resultwhenconnectingthebattery wire,duetoan
initialchargingof the internal input capacitor.
3.06 Remote Switch for Inverter
Operation - Fig. 1
3.06.1 All material used for the remote
switch should be U.L. listed and installed per low
voltage, Class 2, wiring code.
3.06.2 A remote switch may be connected
tothevioletwiremarked"RemoteSwitchHookup"
inthewiringcompartment.Removethevioletwire
from the +24 VDC battery positive input terminal.
Connect the violet wire to the load terminal of a
an external AC power source is applied to the
inverter’s AC outlet or its hardwire output.
CAUTION: Besure the inverter'scircuitbreakeror
fuseare turned"OFF" duringinstallation.
NOTE: All wiring must follow the National Electric
Code,Provincial orothercodes ineffect atthe time
of installation, regardless of suggestions in this
manual. All wires should be copper conductors.
3.03 Mounting
3.03.1 Locate a suitable, secure vertical or
horizontalmountingsurface as close to the battery
as possible without being in the same air tight
compartment. The maximum recommended dis-
tance between the mounting location and the
battery is 20 feet.
CAUTION: If mounting the inverter on a vertical
surface,mountwiththefrontcontrolpanelpointing
down.
3.03.2The location should provide adequate
ventilation and clearance to maintain room tem-
perature during operation. At least 1/2 inch of
clearance is required on all sides.
3.03.3 Secure the unit with 1/4 inch screws
or bolts in the mounting slots on the flanges of the
chassis.
3.04 Chassis Bonding Lug - FIG. 1
3.04.1 Connect a #8 gauge or greater cop-
per wire between the bonding lug on the inverter
and the earth grounding system or the vehicle
chassis.
3.05 Battery Cabling - FIG. 1
3.05.1
CAUTION: Assure that hydrogen gas
doesnotaccumulatenearthebatterybykeepingthe
area well ventilated. A spark may result when con-
necting the final battery wiring due to the initial
charging of the internal input capacitor.
3.05.2 Use stranded copper wire between
the battery and inverter as indicated. A line fuse
must be installed between the battery and the
inverter. U.L. requires that the fuse be within 18
inches of the battery.

fused+24VDC.Thecableclampstrainreliefshould
be used to secure the field wires.
3.06.3 The switch should be mounted at a
convenient location in a listed outlet box with
approvedstrainrelief.
3.06.4
NOTE: A remoteswitch, ifinstalled, will
operateonly if the local On/Off switch on the face
oftheinverteris turned"On". Youmayuse several
switches or relays in parallel in lieu of one remote
switch.

3.07.1
CAUTION: Donotconnectanothersource
of AC power directly to the output of the inverter.
This will result in damage to the inverter that is not
coveredunderwarranty!
3.07.2 The 120 VAC output of the inverter is
provided at the GFCI receptacle outlet on the
inverter.
3.07.3 The output is also presented behind
the wiring compartment panel for direct hardwire
wire leads. The black wire is hot, the white wire is
neutral and the green wire is ground. The cable
clamp strain relief should be used to secure the field
wires.
3.07.4 The hardwire A.C. output is not
ground fault circuit interrupt, (GFCI) protected.

5.02.2 Make sure that the inverter is
turned“On”, andthe circuitbreakers arereset.
5.02.3 Check the connection to the
remoteswitch,ifused. +24VDC mustbepresent
at the violet wire for the unit to operate. If not,
check any fuses in the remote switch circuit.
5.02.4 Observe thefault indicating lightson
the front of the inverter.
