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.
Use a 1/0 cable to connect to the inverter. The recommended maximum length
of the inverter cable is 15-ft, and it must be fused within 18 inches of the positive
(+) terminal of the battery.
An inverter cable kit
designed to SAE guidelines can be purchased directly from
Sensata – call for
options.
Torque the DC connections on the inverter to 50-60 lbs.-in.
Torque the inverter bonding lug to 45 lbs.-in. for 6AWG or 40 lbs.-in. for 8AWG.

NOTE: Using a smaller cable may cause the inverter to go into low battery or
high temperature prematurely.
NOTE: 100% duty rating assumes the inverter is operating at its full rated
output power continuously for at least an hour. The 50% duty rating
assumes that the inverter is operating at its full rated output power for
up to 15 minutes and then operating with a load less than 25% of its
full rating for at least 15 minutes before returning to full power and
repeating. Alternately it can also operate at 50% of its rated output
power continuously. Table assumes operating in an ambient
temperature of 25°C (77°F). For higher ambient temperatures,
additional derating may be required (i.e. may need to use a larger cable
size).

AC INPUT/OUTPUT CONNECTIONS

WARNING: Do not connect another source of AC power
directly to
the AC output of the inverter. This will
result in damage not covered under
warranty.
GFCI:
A 20A GFCI is installed into the side of the inverter, except for “H” suffix
hardwire only versions where it is omitted. The rated output of the inverter is
12.5A. If a 20A load is applied to the GFCI, the 15A AC output breaker
installed on a 12LP15 inverter only will eventually trip. The 12LPC15 allows for
20A of bypass current, so a 20A breaker is used. If 20A of load is connected to
the inverter or inverter/charger while in inverter mode, the inverter will shut
down in overload.
Hardwire Interface:
Remove the cover for hardwire AC wiring. Insert AC input and output wiring
through the AC Output cable clamps to protect the wires from the metal edge of
the hole. Connect the AC wiring to the provided internal terminal blocks. Be
sure to connect the AC input wiring to the AC input terminal blocks, and the
AC output wiring to the AC output terminal blocks. The AC terminal block
will accept 14-8 AWG wire. Proper torque for the AC terminal blocks is 10lbs.-
in. The 12LP15 should use 14AWG minimum for the AC output. The
12LPC15 should use 12AWG minimum for the AC input and AC output.
Connect the hot wires to the black terminal, the neutral to the white terminal,
and the ground to the green terminal.

REMOTE INVERTER ON/OFF SWITCH
Remote Inverter ON/OFF Switch – Customer Supplied
Two types of remote switches may be used to control the inverter/charger.
They are momentary or snap switches. However, the type of switch used can
only be used in specific circumstances. For non “-R” suffix versions, a
momentary switch must be used. For remote only “-R” suffix versions, a snap
switch must be used. If a snap switch is used in place of a momentary switch,
the inverter may not respond correctly.
In remote only mode, the snap switch will turn the inverter on and off when in
inverter mode. When in charger mode, it will switch the inverter state between
off and standby.
In non-remote only mode, the momentary switch will toggle the inverter state
between on and off, or standby and off while in charge mode.
The remote switch may be customer supplied or ordered separately from the
factory. 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 left side of the inverter. 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.

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 beneath the AC wiring box
on the left side of the inverter shows the current state of the inverter.
Inverter Power Mode
The inverter can now be turned on by using the local or remote switch. When the
inverter is on, the local Status LED will
be a constant green. When the Local
On/Off switch is enabled in assemblies without the “R” suffix, any switch may turn
on or off the inverter. When using the local switch, any remote switch must be a
momentary type.
With the “R” suffix, only the remote switch will turn on the inverter. The remote
switch must be a snap type. The Local On/Off switch will be inactive.
The function of the switch will depend on the mode the unit is running in, and if the
Aux tab is enabled and being used.
Note: The LED will blink a yellow-green pattern indicating the battery type on the
12LPC15 during the first 5 minutes of operation upon initial power-up. The
pattern will cease if a warning or fault occurs.
External Power Mode - Bypass

The loads attached to the inverter output will operate directly from the external AC
power line independently of the inverter ON/OFF status. If the inverter is left ON
(standby mode), the built-in bypass relay will automatically cycle back and forth between
“Inverter Power” mode and “External Power” mode depending on the availability of the
external AC power line.
External Power Mode -Battery Charger

The battery charger will engage automatically and independently of the inverter
ON/OFF status. The 3-step charging process modes are: Constant Current (Bulk),
Constant Voltage (Acceptance), and Float. The Battery Temperature Sensor (BTS) must
be plugged into the “TEMP SENSE” connector on the inverter. If not, the charger will
not operate.

Switch Options
The inverter can be configured by the factory or through the CAN configuration
interface to have different local and remote switch configurations. The local switch may
be set to enabled or disabled. The remote switch may be set to snap or momentary.
“Snap” and “momentary” describe the type of switch that is used.
There is one switch combination that isn’t allowed. If the local switch is set to enabled,
the remote switch must be set to momentary. If the remote is set to snap, the inverter
may not respond correctly to changes in the remote switch’s state. This is also true if the
inverter remote switch is set to momentary, but a snap style switch is used.

Table 5 - Switch Options
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.
NOTE: If the inverter is shutdown in low battery conditions, the unit will go into a hard
shutdown for under voltage protection (UVP) if the battery is not charged up to
the inverter’s auto recovery voltage of 13.5V after 15 minutes. The inverter will
be completely off and there will be zero current drawn in UVP. Cycling the
ON/OFF switch (remote switch only for “R” suffix) will immediately restart the
inverter if the voltage is above the Low Battery Threshold at the DC input
terminals.
NOTE: The inverter may be de-rated when the input voltage approaches the low
battery set-point. To conserve battery voltage, the internal inverter fan
may turn off. This will cause the inverter to go into high temp shutdown
if the load is high enough.
Shutdown Timer

As an alternative to sleep mode, a factory configured 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. Following shutdown, the DC input
current will be
less than 0.5mA. Cycling the ON/OFF control will restart the inverter.
Sleep Mode (Load Sense)

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 20W 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.

18
 12222112LPC15ManualRevA.docx

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.
Auxiliary Control
The “AUX” tab on the side of the inverter allows for additional functionality of the
inverter. The “AUX” tab is set to disabled by default at the factory. To change it,
contact the factory or use the CAN Setup Tool. To use the AUX tab, battery voltage
needs to be applied to it. The connection should be fused.
Mode Description of Mode
Disabled Aux tab doesn't do anything.
Utility Aux tab required to be high to enable inverter, charger,
and bypass.
RV Aux tab required to be high to enable inverter. Charger
and bypass not affected.
Control Aux tab required to be high to enable charger mode.
Inverter and bypass not affected.
Table 6 - Aux Control

The “AUX” tab has no effect on charger and bypass functions if enabled on a 12LP15
inverter only.
Note: Applying battery voltage to the “AUX” tab while the inverter is off will cause the
inverter to draw about 170mA. Remove power from the “AUX” tab when not
using the inverter to conserve battery power.
Figure 9 - Aux Connection
Battery Options
The charger can be set to charge three different types of batteries. Wet Lead Acid, AGM,
or Gel. The charger is set to Wet Lead Acid by default by the factory. The battery type
may be changed at the factory or by the CAN configuration interface. To determine what
type of battery the inverter is configured for, monitor the LED blink code at startup. If
the inverter is configured for Wet Lead Acid, the LED will blink Amber-Green. For

AGM the blink code is Amber-Green-Green. For Gel the blink code is Amber-Green-
Green-Green.
Branch Circuit Rating (LPC only)
The branch circuit rating (“BCR”) can be set to 0, 5, 10, 15, or 20A. If set to 0A, the
charger will not enable. Bypass will still be available. The default factory setting is 15A.
The BCR may be changed at the factory or by the CAN configuration interface.
AC Line Qualify Time (LPC only)
The AC line qualification time can be set to any value between 5 and 60 seconds, in 1
second increments. This default setting is 30 seconds. This setting adjusts the time that
it takes for the charger and bypass to start once qualified AC power has been applied to
the charger input. This setting may be changed at the factory or with the CAN
configuration interface.
CAN Instance and Baud Rate
The CAN instance (address) can be changed from 1 – 13. This is useful if there are
multiple inverters being used on the same CAN network. Multiple inverters should not
share the same CAN instance. The Baud Rate may be changed between 250k and 500k.
The default settings for the inverter are Instance 1 and Baud Rate 250k. These values
may be changed at the factory or by the CAN configuration interface.
NOTE: In the highly unlikely chance that an internal error occurs to the memory of
the inverter/charger, the inverter/charger configuration will reset to the
12LPC15 standard. All settings will revert to the standard default
configuration, except the battery setting will be set to GEL.

INVERTER CONFIGURATION TOOL
The inverter/charger settings described in the previous section may be adjusted with a
CAN interface kit, which is sold separately. The kit consists of a Kvaser CAN interface
which connects to a USB port on a laptop, a DB9 to RJ45 adapter, a terminating resistor,
and a Windows PC program that can be installed on a x32 or x64 machine.
After the software has been properly installed, the Kvaser device may be plugged into
the computer. The first time the Kvaser is connected, the computer may need to
download the appropriate Kvaser drivers from the Kvaser website. Once the Kvaser
device is ready to be used, the terminating resistor and DB9 to RJ45 adapter may be
connected to the inverter CAN port.
Once the inverter is turned on, the Configuration Interface may be opened on the
laptop. Once open, the tool will automatically look for a CAN device on the network.
Once found, it will automatically connect and display the current inverter/charger
settings.
Note: Only one CAN enabled inverter can be connected at a time. To make a settings
change, click on a parameter and the available options will appear in a drop-down
menu. Once a setting is changed, the change is immediately set into the inverter’s
memory. After making all the settings changes it is prudent to turn the inverter
off for 30 seconds and then turn it back on for the setting changes to take effect.
The settings may be saved to a configuration file. The configuration file maybe used to
program any additional units that are to be programmed with the same settings.
