Comprehensive Protection

RS400 is designed to meet UL 458 and CSA C22.2 No. 107.1 safety standards and it is compliant with FCC Class B.

RS400 comes equipped with numerous protection features to guarantee you safe and worry-free operation.

Protection feature	This protection feature…

Low voltage indication	Protects the battery from becoming completely discharged. The
and shutdown	Low Battery light indicates that input voltage is low (10.5 volts).
	If the input voltage drops below 10.0 volts the RS400 shuts down
	automatically and the Inverter ON light turns off. The RS400
	recovers automatically when the input voltage comes up to about
	12.6 volts.

High voltage shutdown	Protects the RS400 by disabling the AC output when the input
	voltage rises to 15.3 volts or more. The AC output is enabled
	when the input voltage drops to 14.5 volts.

Over-temperature	Disables the AC output of the RS400 when the internal
shutdown	temperature rises to unacceptable levels due to higher ambient
	temperature or overloading. The RS400 recovers automatically
	when it cools down.

Overload protection	Disables the AC output of the RS400 if the appliance connected
	to the inverter exceeds the 400 watt rating of the inverter. The
	RS400 will have to be reset. (See “Resetting After a Fault or
	Shutdown” on page 2–9.)

Supplemental circuit	Trips and disables the AC output when a current in excess of 7.5
protection	amps is drawn from the RS400. The supplemental circuit
	protector can be reset to enable the unit to operate again after
	clearing the overload condition. (See “Resetting After a Fault or
	Shutdown” on page 2–9.)

Short circuit protection	Disables the AC output of the RS400 when a short circuit is
	applied on the AC output. Once the short circuit is cleared, the
	RS400 will have to be reset. (See “Resetting After a Fault or
	Shutdown” on page 2–9.)

Ground fault circuit	Trips and disables the output of the RS400 when a ground fault
interrupter (GFCI)	current is detected. The output can be enabled again by resetting
	the GFCI, once the ground fault is cleared. (See “Ground Fault”
	on page 2–9.)
