3. INSTALLATION  
resultwhenconnectingthebatterywiringduetoan  
initial charging of the internal input capacitor.  
3.05.2 Use stranded copper wire between  
the battery and inverter as indicated. A fuse must  
be installed between the battery and the inverter.  
U.L. requires that the fuse be within 18 inches of  
the battery.  
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.

and Fusing Guide  
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.  
3.05.3 NOTE: Using smaller input cable  
or longer length will greatly degrade the inverter  
peak performance.  
3.03 Mounting  
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  
when connecting the battery wire, 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.  
3.03.1  
Locate a suitable, secure flat  
mounting surface 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. 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.

3.04.1 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.

electrical supply outlet.  
5.02.1 Connect a 100 watt light bulb to the  
inverter output.  
5.02.2  
Make sure the inverter is turned  
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  
remote switch. The line side of the switch must be  
connected to the DC power source with a 3 Amp  
fuse within 18" of the source. The cable clamp  
strainreliefshouldbeusedtosecurethefieldwires.  
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.  
"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.  
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.  
a) The Low battery light indicates a low  
battery condition. Switch the inverter “Off” for 5  
seconds, then “On” again. The light coming on

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!

the GFCI protected female receptacle cord at-  
tached to the inverter.
