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
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. |
|
|
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 |
|
|
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 |
|
|
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 |
|
|
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 |
