Protections
6.4 oVeRLoAD PRotectIon
The inverter will automatically shut down when the continuous draw exceeds rated Watts. It will be
latched in shut down condition and will require manual reset by switching off the oN/off Switch (2,
figs 3.1.1 and 3.2.1), waiting for 3 minutes and switching oN again (internal latching circuit does not
de-energize immediately after Switching off). SSW-1000/1500/2000 cannot be reset by using the oN/off
Push button on the remote Control SSW-r1-12b. Manual reset will be required using the oN/off Switch
on the inverter (2, figs 3.1.1 and 3.2.1) as described above.
refer to Section 7 - Troubleshooting Guide for more details of symptoms, causes and remedies related to
this protection.
6.5 SHoRt cIRcUIt PRotectIon
This protection is similar to overload protection described at subsection 6.4 above.
6.6 GRoUnD FAULt PRotectIon
Protection has been provided to shut down the inverter (in SSW-350 & 600) or trip the GfCI (in SSW-
1000,1500 & 2000) in case the chassis of the AC load becomes live due to leakage from live portion(s)
inside the load to the chassis of the load. SSW-350 & 600 will shut down immediately if leakage is more
than the maximum allowance of 5mA. reset procedure for SSW-350/600 will be same as at subsection 6.4
above.
In SSW-1000, 1500 and 2000, the GfCI receptacle will trip and interrupt AC power to the load in case
current > 5mA leaks to earth Ground when a person touches the live chassis of the load. Please note that
although the GfCI will trip, the inverter will not shut down and AC power will be available by re-setting
the GfCI.
refer to Section 7 - Troubleshooting Guide for more details of symptoms, causes and remedies related to
this protection.
6.7 LoW InPUt VoLtAGe ALARM
An alarm will sound when the voltage at the input terminals of the inverter drops to 11.0V ± 0.3V. This
is an indication that either the battery terminal voltage has dropped due to its discharged condition and
needs to be re-charged or there is an excessive voltage drop across the wires connecting the inverter
to the battery (due to use of thinner and longer length of wires that will produce higher voltage drop
at higher loads or due to loose connections). The user should stop operation of the load at this time
since the inverter will shut down automatically shortly thereafter, when the input voltage at the inverter
further drops to 10.5 ± 0.3 Volts. In case the alarm is due to the discharged condition of the battery, start
your engine to recharge the battery / use an appropriate battery charger.
The alarm resets automatically when the DC input voltage rises to 11.5 ± 0.2V.
refer to Section 7 - Troubleshooting Guide for more details of symptoms, causes and remedies related to
this protection.
note: It is normal for the alarm to sound while the unit is being connected to or disconnected from the
power source. this is not indicative of a problem.
