 Pure Line 400 Pure Sine Wave DC 
to AC Power Inverter. Read and understand this manual before installing and 
operating this inverter. Keep this manual for future use.
It delivers a true AC sine wave identical to that of commercial power. Use this 
inverter to power AC appliances in your vehicle. Pure Sine Wave AC means 
that your sensitive electronics, such as audio/video systems, computers, and 
communications equipment will operate properly. Furthermore, appliances with 
motors operate cooler, quieter, and more efficiently when they are powered by 
pure sine wave AC.
The inverter is powered from 12 volt DC and it will continuously deliver 400 watts 
AC power at 115 volts, 60 Hz. Superior surge capability of 800 watts allows the 
inverter to start most difficult motorized appliances. Advanced microprocessor-
controlled circuits run cooler and are more reliable than competing units. The 
Pure Line 400 operates at high efficiency (up to 90%), that results in long run 
time and extended battery life compared to other inverters with this level of 
power output. A 2.1A USB power port provides a convenient way to power USB 
devices, including tablets, e-readers, smartphones, and other mobile electronics.
The Pure Line 400 comes with a separate ground terminal typically found on 
higher capacity units. This terminal helps to reduce the noise caused by power 
conversion when using radio frequency devices.
The DC terminals have been designed with protective covers to minimize the risk 
of accidental shortage when handling the DC cables. This inverter bonds neutral 
to ground, just like utility power. The enclosure vents have been minimized to 
reduce the risk of pest intrusion in arid tropical climates. 
This inverter has added safety features including ETL certification (UL458, CSA 
22.2), conformal coating to protect circuits from dust and moisture, ground fault 
protection, and DC terminal protection.
The Wagan Pure Line 400 Pure Sine Wave Inverter is an indispensable addition 
to your compliment of mobile power equipment. With minimal care and proper 
treatment, it will provide years of reliable service.
