NOTE: Please see detailed symptoms, causes and remedies in the troubleshooting guide at page 14.
OVER TEMPERATURE PROTECTION
The unit is cooled by 2-speed fan(s). The fan(s) will run at slower speed up to certain threshold of power
output and at full speed thereafter. In case the fan fails or if the cooling is inadequate due to higher
ambient temperature or restricted air flow, the temperature inside the inverter will be too high and the
unit will automatically shut down. Allow the unit to cool for at least 15 minutes before restarting after a
heat-related shutdown.
LOW BATTERY VOLTAGE PROTECTION
This condition is not harmful to the inverter but could damage the DC input power source. The inverter
automatically shuts down when input voltage drops to 10.5V ± 0.3V.
OVER VOLTAGE PROTECTION
The inverter will automatically shut down when the input voltage exceeds 15.3V ± 0.3V. Input voltage
exceeding 16V could damage the inverter.
OVERLOAD PROTECTION
The inverter will automatically shut down when the continuous draw exceeds rated Watts.
SHORT CIRCUIT PROTECTION
The inverter will shut down. remove the short circuit and restart inverter.
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. 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 avalable by re-setting the GfCI.
LOW INPUT VOLTAGE ALARM
An alarm will sound when the voltage at the input terminals of the inverter drops to 11.0 Volts. 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 electronic device at this
time since the inverter will shut down automatically shortly thereafter, when the input voltage at the
inverter further drops to 10.5 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.
If the low voltage alarm sounds when the battery is fully charged, follow the steps for solving lack of
output power in the Troubleshooting Guide at page 14.
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.
