Maintenance; Troubleshooting Guide - Thiele Asian Electron PSW1500W Series Instruction Manual

2-8 Cooling Fan Working Code:
Cooling fan of inverter is through detecting output power and over temperature situation to work.
Regarding the Pure Sine Wave 1500W inverter:
When start to turn on the inverter and output power under 300W, the cooling fan does not start
running. It complies with saving energy sources requirement. Until, output power is up to 300W,
the cooling fan will start to work in order to drop the inner temperature.
Regarding the Pure Sine Wave 2000W inverter:
When start to turn on the inverter and output power under 60W, the cooling fan does not start
running. It complies with saving energy sources requirement. Until, output power is up to 60W,
the cooling fan will start to work in order to drop the inner temperature.
If the ventilation opening is obstructed, the inverter will enter Over Temperature Protection mode
(OTP). The cooling fan will continue working to drop the inner temperature. When the
temperature comes down to normal situation, the inverter will turn on automatically.

Maintenance:

Very little maintenance is required to keep your inverter operating properly.
You should clean the exterior of the unit periodically with a dry cloth to prevent accumulation of
dust and dirt. At the same time, tighten the screws on the DC input terminals.

SYSTEME
Use true RMS reading meter
and cable. ( Ref. point 2-4-7)
Reduce load
Recharge battery,
check connections and cable.
( Ref. point 2-5 & point 2-6)
Improve ventilation.
Make sure ventilation openings
in inverter are not obstructed.
Reduce ambient temperature.
Check AC wiring for short
circuit or improper polarity. (hot
and neutral reversed)
Remove load.
