Inverter Mounting Recommendations
NOTE: The inverter mounting location should provide adequate ventilation and clearance to maintain room temperature during operation. At least ½” of clearance is required on all sides except the bottom.

1. Locate a suitable, secure mounting surface as close to the batteries as possible without being in the same compartment.
2. Mount the inverter using four ¼-20 steel bolts, flat and lock washers, and nuts.

Mounting for all models (units are in inches)

DC WIRE GAUGE & FUSING

Inverter Cable

• An “Inverter Cable Kit” (positive cable, negative cable, and proper fuse) is needed to connect the inverter to a battery bank. An 8-gauge wire is also recommended to connect the inverter’s bonding lug to system ground.
• The inverter cable length and the size of the inverter will determine the cable gauge and the fuse size to use. The maximum inverter cable recommended is 15-ft; it must be fused within 18 inches from the positive (+) terminal of the battery.
• Cross reference the inverter model and the estimated cable length in the table below to determine the proper cable gauge and fuse size. An inverter cable kit designed to SAE guidelines can be purchased directly from Sensata – call for options.

Minimum Cable and Max Fusing Guide at 5% Voltage Drop at Full Output

Full Load (Amps DC)

| Inverter to Battery Estimated Cable Length in Feet
1 to 10 feet| 11 to 15 feet
110| 4-ga, 200A Fuse| 2-ga, 250A Fuse

To make your own “Inverter Cable Kit,” follow the below recommendations:

1. Use stranded copper cables in all cases.
2. USE SGX cross-linked polyurethane insulation type that complies with the high temperature insulation requirements (125°C.) of SAE J-1127 and vehicle manufacturer requirements.
3. For 1/4″ ring lugs, use Waytek 35000 or JST 22-6 for 4 gauge cable . Use Waytek 35020 or JST 38-S6 for 2 gauge cable.

Proper installation of cable into DC terminal cover

AC OUTPUT CONNECTIONS

WARNING: Do not connect another source of AC power directly to the output of the inverter. This will result in damage not covered under warranty. The inverter’s 120 VAC output power is provided at the GFCI receptacle or through the hardwire connections for the “H” option.
“H” Option – Hardwire Interface:
Remove the cover for hardwire AC wiring. Insert AC wiring through the cable clamp to protect the wires from the metal edge of the hole. Use the supplied wire nuts and wire Black to Black, White to White, and Green to Green.

REMOTE INVERTER ON/OFF SWITCH

• Remote Inverter ON/OFF Switch
  An optional remote switch with an integral LED can be purchased and used to control the inverter. Mount the remote switch in a convenient location. Route the cable to the inverter and plug into the connector on the back. See mounting hole size in the Appendix section. Also see Appendix for 20′ cable part number.
  Note: The local indicator light will be green when functioning correctly, while the remote ON/Off switch will have a solid red light when functioning correctly.

• Remote Inverter ON/OFF Switch – Customer Supplied
  An optional customer supplied remote switch can also be used to control the inverter. Mount the remote switch in a convenient location. Using 18 gauge wire and an insulated ¼” female faston, wire between the “Remote ON/OFF” connection on the right side of the inverter and the remote switch. Wire from the remaining connection on the remote switch to the battery positive (+) terminal. Be sure to install a 5-amp in-line fuse in series within 10 inches from the positive (+) terminal of the battery.

Typical DC Wiring Diagram

OPERATION

Once the inverter has been fully installed and wired, and DC power has been applied, the inverter is ready to turn on. The Status LED to the right side of the GFCI shows the status information of the inverter.

Inverter Power Mode

1. Turning the Inverter “ON”
   The inverter can now be turned on by using the front panel switch (standard or “H” version only) or the remote switches – 2 options: cable assy or customer provided switch. When the inverter is On, the local Status LED will be a constant green. The optional Sensata provided remote switch will be a constant Red. Any switch may turn on the inverter. All switches must be off to turn off the inverter.

Sleep Mode

1. Sleep Mode
   The inverter has a Sleep Mode feature which if enabled can significantly reduce DC power drawn over long periods of no-load operation to help preserve battery life. If Sleep Mode is enabled the inverter output will automatically turn off when AC loads greater than 15W are not present for 60 seconds. The inverter will check for the presence of a load once a second and will automatically restart on when it reappears. NOTE – The LED on the GFCI will blink when the inverter has gone to sleep.
   NOTE – While in sleep mode it may take up to one second for the load to receive power when the load is applied.
   NOTE – The LED on the GFCI will blink when the inverter has gone to sleep. Refer to page 7 for configuration information.

Shutdown Timer

1. Shutdown Timer
   As an alternative to sleep mode, a user-selectable shutdown timer is available to disable the inverter after fixed periods (regardless of output load). Standard timer settings are OFF, 30 minutes and 60 minutes. Refer to page 7 for configuration information. Following shutdown, the DC input current will be less than 0.5mA. Cycling the ON/OFF control will restart the inverter.

Low Battery Shutdown

1. Low Battery Shutdown
   Low Battery Shutdown is a protective measure to prevent deep discharge of the battery and/or to make sure that the starting batteries have enough power to start the vehicle. There are two user-selectable shutdown points of 10.5VDC & 11.7VDC. Refer to page 7 for configuration information.

THEORY OF OPERATION

Inverter Power Mode
Usage: Any 120 VAC, 60 Hz single phase product within the inverter’s power rating. The inverter front “STATUS” LED will be Green while the inverter is on. The AC power produced by the inverter comes from the energy stored in the battery bank through a sophisticated electronic inversion process. A transformer, a Metal Oxide Silicon Field Effect Transistors (MOSFET), a filter capacitor and microprocessor control are used to generate clean AC power. The inverter will operate at DC input voltages ranging from 10.5 to 16 volts. Above 16 volts the inverter may stop operating due to input voltage being out of range. The inverter can tolerate up to 24V DC for 5 minutes. Durations longer than 5 minutes will result in a shut down. Input voltages above 24V DC will result in an immediate shutdown. The inverter will restart when the input voltage drops below 16V DC. When the input voltage drops to 10.5/11.7 volts, the inverter will stop operating due to a low battery condition. When the lead acid battery bank voltage drops to 10.5 volts, the battery is fully discharged.
Note: The signal output waveform produced by the inverter when in “inverter mode” is pure sinusoidal. It has a total harmonic distortion of less than 5% at nominal input.

Troubleshooting

1. No AC output power during inverter mode:

   • Check the in-line fuse which is located within 18” from the battery’s positive post.
   • DC connections tight and clean?
   • Is output circuit breaker tripped?
   • Check the inverter power switch and remote power switches. Switches inactive in “R” and “HR” configurations.
   • Check the GFCI to see if it is tripped, and reset if necessary.
   • If GFCI is set, disconnect all loads and connect a test light.
   • If the test light is off, replace GFCI or return the inverter for service.
   • For model 12LP10H, check AC hardwire connections.
     Note: If the status LED’s are illuminated, refer to the “LED Status Chart” on the previous page for additional information.

2. Low Battery: The use of a battery isolator is not recommended due to excessive voltage drop across isolator terminals.

   • Battery voltage must be above 10.5/11.7 VDC ) (measured at the inverter) for the inverter to be on.
   • Check for proper DC wire gauge (see DC Wire Gauge & Fusing section)

3. Overload: Unplug all loads and reset the inverter On/Off.

   • If the overload condition clears, check for short circuits or check load size versus inverter output wattage size.
   • If the overload persists, possible failed inverter

4. High Temperature: Let the inverter cool down

   • Verify that all vent openings are clear of obstruction.
   • Reduce ambient temperature and/or load.
