1. GENERAL
1.01 MDS Power inverters have been designed

longlife. Theyutilizepatentedconstructionmeth-
ods and high technology electronic parts and
circuitry.

CAUTION: Inverters produce hazardous
voltages,toavoid riskofharmorfiretheunitmust
be properly installed. There are no user service-
able parts inside, do not remove the cover.
CAUTION: Theinvertershouldnotbemountedin
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
correctpolarityisnotobservedwheninstallingthe
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
batteries is dangerous. Batteries generate explo-
sivegasesduringoperation. Thereisarisk of acid
exposure. There is also a risk of high current
dischargefromshortingthebatterythatcancause
fire and explosion.
CAUTION: Be surethe inverter'scircuitbreakeror
fuse are turned "OFF" during installation.
2. DESCRIPTION
2.01 The inverter converts 24 VDC to 120
/ 240 VAC, 60 HZ, having a pure-sine wave form.
2.02 The inverter has internal protection
against output short circuit, output overload and
high temperature conditions. Also, there is a
thermally controlled cooling fan.
2.03 The inverter is designed to operate any
120VAC, 60HZsinglephaseappliance,equipmentor
toolwithinits powerratings.

3. INSTALLATION
3.01The following instructions should be thor-
oughlyread andunderstoodbefore installation.
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
correctpolarityisnotobservedwheninstallingthe
DC input cables.
CAUTION: Damage to the inverter will occur if
an external AC power source is applied to the
inverter’s AC outlet or its hardwire output.
CAUTION: Be sure the inverter's circuit breaker
or fuse (if needed) are turned "OFF" during instal-
lation.

3.05.3 NOTE: Using smaller input cable or
longer length will greatly degrade the inverter
peak performance.
IMPORTANT NOTE FOR VEHICLE
INSTALLATION:
Donotusethevehiclechassis
as the negative return in place of a return cable.
Use the same size cable as the positive connec-
tion and run directly to the battery/alternator.
3.05.4 Install the wires at the battery, in-
verter and then fuse holder. Make sure that
good, clean connections are made. Use care not
totouchthepositiveandnegativewirestogether.
This will result in a violent spark and could result
in exploding batteries and fire.
3.05.5 The battery input terminals are lo-
cated in the wiring compartment. A mounting
spark may result when connecting the battery
wire, due to an initial charging of the internal
input capacitor.
3.05.6
CAUTION: Connecting the inverter
incorrectly to the battery will cause damage that
is not covered under warranty.
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"
in the wiring compartment. You should first
remove this violet wire from the battery positive
inputterminal;thenconnectthevioletwiretothe
load side of the switch. The cable clamp strain
relief should be used to secure the field wires.
3.06.3 The switch should be mounted at a
manual. All wires should be copper conductors.
3.03 Mounting
3.03.1 Locate a suitable, secure vertical or
horizontal mounting surface as close to the bat-
teryaspossiblewithoutbeingin the same air tight
compartment. The maximum recommended dis-
tance between the mounting location and the
battery is 20 feet.
NOTE: Mount the inverter on a vertical surface
with the front control panel pointing 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 Wiring - FIG. 1
3.05.1
CAUTION: Assure that hydrogen
gas does not accumulate near the battery by
keeping the area well ventilated. A spark may
result when connecting the final battery wiring
due to an 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.

convenient location in a listed outlet box with
approved strain relief.
3.06.4
NOTE: A remote switch, if installed,
will operateonly if the local On/Off switch on the
face of the inverter is turned "On". You may use
several switches or relays in parallel in lieu of one
remote switch.
3.07 120 VAC / 240 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!
3.07.2The 120 VAC output of the inverter is
provided at the GFCI receptacle outlet on the
inverter.
3.07.3 The dual output 120 / 240 VAC is
presented behind the wiring compartment panel
for direct hardwire wire leads. The two black wires
are hot (use one black for 120 VAC), 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.
GFCI outlets should be installed at all appropriate
locations per NEC 551. The GFCI outlet should be
Leviton, Model 6599 or UL listed equivalent. The
GFCI outlet should be Hubbell GFR5352XX (20A)
or GFR5252XX (15A).
3.07.5 The remote AC outlets should be
mounted at a convenient location in a listed outlet
box with approved strain relief.
4. START UP/OPERATION
4.01To operate the inverter, turn the switch to
“ON”. Assure that the output breakers are reset.
Ifthe remote switch is used, the inverter is turned
“On” or “Off” by the remote switch.

5.02 If the inverter fails to operate, use the
following troubleshooting procedure.
5.02.1 Connecta100wattlightbulbto the
inverter output.
5.02.2 Make sure that the inverter is
turned “On”, and the circuit breakers are reset.
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 the fault indicating lights
on the front of the inverter.
a) The Low input voltage light indicates a
low batterycondition.Switchtheinverter“Off”for
5 seconds, then “On” again. The light coming on
again indicates a fault in the battery wiring, bat-
tery capacity and voltage or the line fuse.
b) The Overload light indicates an output
wiringshortcircuitoraloadthatistoolargeforthe
power rating of the inverter. Switch the inverter
“Off”, remove the short circuit or excessive load
from the output, then switch the inverter back
“On”. c) The High temperature light indicates the
inverter has overheated. The unit will automati-
cally turn back on when it has cooled to 400C.
Verify that the inverter is not in a closed compart-
ment and that the fan is not blocked.
5.03 Call MDS Power, Inc. for technical assis-
tance and/or a return authorization number if the
