Understanding Error Codes
If the products connected to PowerSource 400 do not operate and the alarm is sounding, check PowerSource 400 LED screen for an error code.
Troubleshooting Reference
Error Possible Cause Solution
E01 Low voltage shutdown because battery is discharged. Recharge battery by plugging the AC power cord into a wall outlet.
E03 Overload shutdown while supplying backup power. The AC product(s)
connected are consuming more than PowerSource 400’s five-minute
power rating.
The AC products connected have a surge power that exceeds
PowerSource 400 surge capability.
The AC products connected are short-circuited
Use products with a total power consumption within PowerSource 400’s continuous power rating of
320 W.
Use products with a total starting surge power within PowerSource 400’s capability of 640 W.
Have the load serviced by a qualified technician.
E04 Over-temperature shutdown has occurred. PowerSource 400 has
overheated due to poor ventilation, excessive ambient temperature, or
power demand beyond the unit’s five-minute output power capability.
Disconnect products from the AC outlets. Allow the unit to cool for 20 minutes. Clear blocked fan or
remove objects covering unit. Move the unit to a cooler place. Reduce load to less than 320 W if
continuous operation is required.
Problem Problem/Symptom Solution
PowerSource 400 will not
turn on.
Battery is discharged and utility power is not available
at the wall outlet.
Ensure power is available at the wall outlet.
No power available at the
120 VAC outlets.
AC outlet has been overloaded or the circuit breaker has
tripped.
Reduce the number of products plugged into the AC outlets. Check the circuit breaker at the back of the
unit. If necessary, reset the breaker by pushing it fully inward.
Products connected to unit
lose power.
PowerSource 400 has detected an overload condition.
PowerSource 400 has detected an over-temperature
condition.
PowerSource 400 has exhausted its available battery
power.
PowerSource 400 may require service.
Make sure the products plugged into
the AC outlets are not overloading the five-minute output power
rating of the unit when supplying backup power. Try removing or substituting some of the products.
Disconnect products from the AC outlets. Make sure the products plugged into
the AC outlets are not
overloading the continuous output power rating of the unit when supplying backup power. Allow the unit
to cool, increasing ventilation if necessary. I
f the unit is left on, it restarts automatically when the unit
cools down 20 degrees.
PowerSource 400 shuts down when all available battery power has been used. Allow the unit to recharge
for 20 hours before continuing to use the unit.

Products connected to unit
malfunction or overheat.
Products connected to PowerSource 400 do not accept
modified sine wave form.
Your application is not compatible with PowerSource 400 modified sine wave output. See “Precautions
for Using Rechargeable Appliances” on page 2.
Inadequate run time. PowerSource 400 battery is not fully charged.
Battery is near the end of its useful life.
Charge the battery by leaving PowerSource 400 plugged into a wall outlet at least 20 hours.
As the battery ages, the available run time decreases. The internal battery also ages prematurely if
PowerSource 400 is installed in a hot environment. See “Battery Replacement” on page 5.
