Comprehensive Protection

TS400 is designed to meet UL 458 and CSA C22.2 No. 107.1 safety

standards and it is compliant with FCC Clas s B.

TS400 comes equipped with numerous protection features to guarantee

you safe and worry-free operation.

Low voltage alarm and
shutdown Protects the battery from becoming completely discharged. The
Low Battery light and audible alarm indicate that input voltage is
low (10.7 volts). If the input voltage drops below 10.3 volts, the
TS400 shuts down automatically and the Inverter ON light turns
off. The TS400 recovers automatically when the input voltage
comes up to about 12.6 volts.
High voltage shutdown Protects the TS400 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
shutdown Disables the AC output of the TS400 when the internal temperature
rises to unacceptable levels due to higher ambient temperature or
overloading. The TS400 recovers automatically when it cools
down.
Overload protection Disables the AC output of the TS400 if the appliance connected to
the inverter exceeds the 400 watt rating of the inverter. The TS400
will have to be reset. (See “Resetting After a Fault or Shutdown” on
page3–7.)
Supplemental circuit
protection Trips and disables the AC output when a current in excess of 7.5
amps is drawn from the TS400. 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
page3–7.)
Short circuit protection Disables the AC output of the TS400 when a short circuit is applied
on the AC output. Once the short circuit is cleared, the TS400 will
have to be reset. (See “Resetting After a Fault or Shutdown” on
page3–7.)
Ground fault circuit
interrupter (GFCI) Trips and disables the output of the TS400 when a ground fault
current is detected. The output can be enabled again by resetting the
GFCI, once the ground fault is cleared. (See “Ground Fault” on
page3–7.)
