Comprehensive Protection

Comprehensive Protection

XS400 is designed to meet UL 458 and CSA C22.2 No. 107.1 safety standards and it is compliant with FCC Class B.

XS400 comes equipped with numerous protection features to guarantee you safe and worry-free operation.

Protection feature

This protection feature…

 

 

Low voltage indication and

Protects the battery from becoming completely discharged. The

shutdown

Low Battery light indicates that input voltage is low (10.7 volts). If

 

the input voltage drops below 10.3 volts, the XS400 shuts down

 

automatically and the Inverter ON light turns off. The XS400

 

recovers automatically when the input voltage comes up to about

 

12.6 volts.

 

 

High voltage shutdown

Protects the XS400 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 XS400 when the internal temperature

shutdown

rises to unacceptable levels due to higher ambient temperature or

 

overloading. The XS400 recovers automatically when it cools

 

down.

 

 

Overload protection

Disables the AC output of the XS400 if the appliance connected to

 

the inverter exceeds the 400 watt rating of the inverter. The XS400

 

will have to be reset. (See “Resetting After a Fault or Shutdown” on

 

page 3–9.)

 

 

Supplemental circuit

Trips and disables the AC output when a current in excess of 7.5

protection

amps is drawn from the XS400. The supplemental circuit protector

 

can be reset to enable the unit to operate again after clearing the

 

overload condition. (See “If there is a short circuit, the

 

Supplemental Circuit Protection button trips.” on page 3–9.)

 

 

Short circuit protection

Disables the AC output of the XS400 when a short circuit is applied

 

on the AC output. Once the short circuit is cleared, the XS400 will

 

have to be reset. (See “Resetting After a Fault or Shutdown” on

 

page 3–9.)

 

 

Ground fault circuit

Trips and disables the output of the XS400 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 3–9.)
