Page 9: Installation
INSTALLATION Mount Inverter WARNING: Power inverters produce hazardous voltages. To avoid risk of harm or fire, the unit must be properly installed. WARNING: Power inverters should not be mounted in a location that may be exposed to rain or spray. WARNING: Power inverters should not be installed in a zero-clearance enclosure. -
Page 10: Dc Wire Gauge & Fusing
An inverter cable kit (positive cable, negative cable, and proper fuse) is needed to connect the inverter to a battery bank. An inverter cable kit designed to SAE guidelines can be purchased directly from Sensata – call for options. Min. Cable and Max. Fusing Guide for 3% Voltage Drop at 100% Output... - Page 11 DC Wire Gauge & Fusing Continued Make an Inverter Cable Kit 1. Use a stranded copper cables in all cases. NOTE: 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.
- Page 12 DC Wire Gauge & Fusing Continued Typical Cable Connection Procedure NOTE: Refer to Figure 4 for a typical DC wiring diagram. See Table 2 for proper cable sizes. 1. Remove the fuse from the fuse holder. 2. Connect the inverter’s bonding lug to ground of the vehicle chassis. 3.

Page 13: Ac Input/Output Connections
AC Input/Output Connections WARNING: Damage to the power inverter will occur if an external AC power source is applied to the inverter’s AC hardwire output. WARNING: Do not directly connect another source of AC power to the AC output of the inverter. This will result in damage not covered under warranty. - Page 14 AC Input/Output Connections Continued Figure 7 AC Input for Charger/Bypass NOTE: The AC input should be protected by a 20 A branch rated breaker external to the inverter/charger. NOTE: The AC output should be protected by a branch rated breaker external to the inverter if required to comply with the National Electric Code, NFPA 70, or the Canadian Electrical Code, C22.1.

Page 15: Bts Connection
BTS Connection Charger operation with a battery temperature sensor, or BTS, cable is required. The BTS measures the battery temperature and automatically adjusts the charger output for the fastest and safest charge. Lead-Acid When batteries are cold, their chemical reaction is slowed, and the battery will not charge as easily in this condition. A charge voltage optimized for room temperature will not charge the battery at low temperatures. - Page 16 BTS Connection Continued Install the BTS 1. Connect the lug end of the battery temperature sensor to the battery. NOTE: Lead-acid battery type will connect the BTS to the negative post of the battery. LFP battery types will connect the BTS to the positive post of the battery. 2.

Page 17: Remote Inverter On/Off Switch
Remote Inverter “On/Off ” Switch Remote Inverter “On/Off ” Switch Installation – Customer Supplied For non “-R” suffix versions, a momentary switch must be used. 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. -
Page 18: Operation
OPERATION Once the inverter has been fully installed, 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 Usage: Any 120 VAC, 60 Hz single phase product within the inverter’s power rating. -
Page 19: External Power Mode
External Power Mode Battery Charger The status LED located on the side of the inverter will blink green to indicate the charging process mode. See the LED Status Chart for additional blink codes. NOTE: The battery charger requires about 8.5 VDC to be present at the DC output before the charger will operate. The battery charger will engage automatically and independently of the inverter on/off status. - Page 20 External Power Mode Continued Battery Charger Continued Battery Type Bulk Charge Phase Current Limit SEE SPEC 1.

- Page 22 External Power Mode Continued Cold Charging (LFP Only) Under normal charger operation, if the battery temperature drops below 5°C/41°F while charging, the charger will switch to 0.1C charging. If the temperature increases to 10°C/50°F, the charger will resume normal charging. If the charger drops to 0°C/32°F, the charger will shut down, and it will restart 0.1C charging at 5°C/41°F.
- Page 23 External Power Mode Continued Equalization Available only for wet lead-acid batteries, this function overcharges the battery in a controlled way to remove sulphate buildup from the battery’s internal plates. Consult your battery manufacturer on how frequently the equalization process should be carried out. Equalization can only be initiated with a RV-C CAN command. The process will not start until a full charge cycle has been completed.

Page 24: Gfci
GFCI A GFCI measures the amount of AC current into the GFCI line side “hot” and “neutral” terminals. Both terminals should measure the same amount of current under normal conditions. Any difference in current is considered the leakage current. If the leakage current is greater than 5mA, the GFCI will trip. A tripped GFCI suggests that there has been a breakdown in the electrical insulation of a connected unit. -
Page 25: Configurations
CONFIGURATIONS Non-Volatile Memory (NVM) Setup Utility The inverter/charger settings may be adjusted with a NVM Setup Utility 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. -

Page 27: Switch Options
Switch Options The inverter can be configured by the factory or through the NVM Setup Utility 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. -
Page 28: Shutdown Timer
Shutdown Timer As an alternative to sleep mode, a factory configured shutdown timer is available to disable the inverter after fixed periods (regardless of the output load). Standard timer settings are “off,” 30 minutes, and 60 minutes. Following the shutdown, the DC input current will be less than 0.5mA. Cycling the on/off control will restart the inverter. Auxiliary Control The AUX tab on the side of the inverter allows for additional functionality of the inverter. -
Page 29: Battery Options
Battery Options The charger can be set to charge four different types of batteries: wet lead-acid, AGM, gel, or LFP. The charger is set to AGM by default by the factory. The battery type may be changed at the factory or through the NVM Setup Utility. -

Alternatively, if the input voltage to the inverter is approaching the low battery setpoint and a heavy load is applied, the output voltage may collapse, causing the inverter to fault like an output short circuit. The inverter power will need to be cycled to restart the inverter.
