Page 11: Dc Wire Gauge & Fusing
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 8 AWG single-strand cable is also recommended to connect the inverter’s bonding lug to ground. The inverter cable length and the size of the inverter will determine the cable gauge and the fuse size to use. -
Page 12: Ac Input & Output Connections
AC Input & 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. WARNING: Do not reverse the input and output AC connections. This will result in damage not covered under warranty. -
Page 13: 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 14 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 27: Gfci Operation
GFCI Operation 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 device. -
Page 28: Optional Lcd Remote
Operation with Optional LCD Remote LCD Remote A LCD remote may be purchased separately for “R” suffix models to connect to the inverter through the RJ45 port on the front of the inverter. The remote display will provide the current input voltage and output wattage of the inverter while in inverter mode. -
Page 29: Configurations
CONFIGURATIONS Setting Configuration with Non-Volatile Memory (NVM) Setup Utility The inverter/charger settings may be adjusted with a NVM Setup Utility kit which is sold separately. See the Appendix for the part number of the kit. 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 32: Ignition Switch Control With The 7-Seg Display Panel
Ignition Switch Control with the 7-Seg Display Panel The 7-Seg Display Panel can be wired to the vehicle ignition circuitry to control operation of the inverter. When the ignition is turned on, the inverter has a built-in delay which will turn it on after 10 seconds. For the inverter to work in this way, the 7-Seg Display Panel must be programmed for this type of operation. -
Page 33: Branch Circuit Rating (Bcr) Max Limit With The 7-Seg Display Panel
Branch Circuit Rating (BCR) Max Limit with the 7-Seg Display Panel The BCR max limit sets the max limit that is adjustable by the 7-Seg Display. For example, if the limit is set to 15 A, the user may only select 0, 5, 10, or 15 amps. If the limit is set to 30 A, the user may then select from 0–30 amps in 5 A increments. -
