1. GENERAL
1.01 Dimensionsinvertershavebeendesigned
andmanufacturedformanyuserapplicationsand
long life. They utilize patented construction
methods and high technology electronic parts
and circuitry.
1.02
CAUTION:
Inverters produce hazardous
voltages, to avoid risk of harm or fire the unit
must be properly installed. There are no user
serviceablepartsinside,donotremovethecover.
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:
Damagetotheinverter will occur if an
externalACpowersourceisappliedtotheinverter’s
AC output or its hardwire output.
CAUTION:
Theinverter containsacircuit breaker
and a capacitor that may produce a spark. Do not
mountinaconfinedbatteryor gascompartment.
CAUTION:
Working in the vicinity of lead-acid
batteries is dangerous. Batteries generate explo-
sive gases during operation. There is a risk of acid
exposure. There is also a risk of high current
dischargefrom shortingthebatterythatcancause
fire and explosion.
CAUTION:
Besuretheinverter's circuit breakeror
fuse are turned "OFF" during installation.
2. DESCRIPTION
2.01 The inverter converts 12VDC, 24VDC or
48VDC depending on inverter model to a 120VAC,
60HZ,havingapuresinewaveformsignaloutput.
2.02 The inverter has a controlled frequency
at 60 HZ + 0.6Hz.
2.03
The inverter has internal protection
against output short circuit, output overload and
high temperature conditions.
2.04 The inverter is designed to operate
any 120 VAC, 60 HZ, single phase appliance,
equipment or tool within its power ratings.
2.05 The inverter has a ventless cover to
protect the inside electronics from the elements
and is designed to be used on scissor lift applica-
tions.
2.06 The inverter is GFCI protected but does
nothavestandardGFCIoutlets.The120VAC,60Hz
output is supplied by a female receptacle cord
attached to the unit.
2.07 The inverter does not have a "On"/"Off"
switch. The unit must be controlled by a remote
switch, a violet wire is attached to the unit for this
purpose.

3.05.3 NOTE: Using smaller input cable
or longer length will greatly degrade the inverter
peak performance.
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 wire as the positive cable and
run directly to the battery.
3.05.4 Install the cables at the battery,
inverter and then fuse holder. Make sure that
clean,tightconnectionsaremade. Usecarenot

3.05.5 The battery input terminals are at-
tached to the unit : Red (+) and Black (-) cable,
having 5/16" ring terminals. A spark may result
whenconnectingthebatterywire, due to an initial
charging of the internal input capacitor.
3.05.6
CAUTION:
Damage to the inverter
will occur if correct polarity is not observed. This
damage is
NOT
covered by warranty.

3. INSTALLATION
3.01 The following instructions should be
thoroughly read and understood before installa-
tion.
3.02
CAUTION:
Inverters produce hazard-
ous voltages, to avoid risk of harm or fire the unit
must be properly installed.
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 external AC power source is applied to the
inverter’s AC receptacle cord.
CAUTION:
Be sure the inverter's circuit breaker
or fuse (if needed) are turned "OFF" during
installation.
NOTE: All wiring must follow the National
Electric Code, Provincial, or other codes in effect
at the time of installation, regardless of sugges-
tions in this manual. All wires should be copper
conductors.
3.03 Mounting
3.03.1 Locate a suitable, secure flat
mounting surface as close to the battery as
possible without being in the same air tight
compartment. Themaximumrecommendeddis-
tance between the mounting location and the
battery is 20 feet. See DC Input Cable Lengths
chart.
3.03.2 The location should have adequate
ventilation and clearance to maintain room tem-
perature while the unit is operating. At least 1/2
inch of clearance is required on all sides.
3.03.3 Secure the unit with #8 or larger
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 Wiring - FIG. 1

CAUTION:
Make sure that hydro-
gen gas does not accumulate near the battery by
keeping the area well ventilated. A spark may
5.02.1 Connect a 100 watt light bulb to the
inverter output.
5.02.2 Make sure the inverter is turned
"On", the output circuit breaker is reset and that
the voltage is at least 12VDC, 24VDC or 48 VDC
(depending on inverter model) at the DC input
terminals. If not, check DC wiring connections
and the line fuse.
5.02.3 Check the connection to the
remote switch, +12VDC, +24VDC or +48VDC
must be present at the violet wire for the unit to
operate. If not, check any in-line fuses in the
+12VDC, +24 or +48 VDC remote switch circuit.
5.02.4 Observe the fault indicating lights
on the front of the inverter.
a) The Low battery light indicates a low
battery condition. Switch the inverter “Off” for 5
seconds, then “On” again. The light coming on
againindicatesafaultinthebatterywiring,battery

3.06.2 A 3 Amp rated remote switch must
be connected to the violet wire marked “Remote
On/Off” coming out at front of the inverter.
Connect the violet wire to the load side of the
remoteswitch. Theline side oftheswitchmust be
connected to the DC power source with a 3 Amp
fuse within 18" of the source. The cable clamp

3.06.3 The switch should be mounted at a
convenient location in a listed outlet box with
approved strain relief. The in-line fuse to be
mounted on appropriate fuse holder.
3.06.4
NOTE:
A remote switch, must be
installed to operate the inverter. You may use
several switches or relays in parallel in lieu of one
remote switch.
3.07 120 VAC Output
3.07.1
CAUTION:
Do not connect another
source of AC power directly to the output of the
inverter. This will result in damage to the inverter
that is not covered under warranty!
3.07.2 The 120 VAC output is provided at
the GFCI protected female receptacle cord at-
tached to the inverter.
4. START UP / OPERATION
4.01 To operate the inverter turn the remote
switchto“On”. Makesurethattheoutputbreakeris
reset.
4.02 Turn the switch to “Off” when the inverter
is not in use.
