AMARAD HELLAS ELECTRONIC AT-502-500VA Instruction Manual

(4) If the transformer is ok, check the appliance(s).
e. When the RED LED lights up
(1) When input voltage is out of normal range, the transformer will go into the high or low voltage
protection status. The output of transformer will be cut off automatically, and the RED LED will
light up.
The output will be automatically restored once the input voltage returns to normal range.
(2) The transformer is built with a thermal sensor to detect the temperature of transformer coils.
When the temperature exceeds the limit, the output of transformer will be cut off automatically,
and the RED LED will light up.
Check if connected appliance(s) exceeds the maximum capacity of transformer. Or wait until
the coils of transformer cool down, the output will be automatically restored.
6. CAUTIONS
● Make sure the appliance is connected to the correct outlets before switching on the transformer.
● Do not connect any appliances whose total power is over the maximum power of the transformer.
● For any appliance with built-in motor or compressor, whose starting power is generally several
times than the rated power that is listed in the rating label. It is recommended to calculate its
starting power at least as twice as its rated capacity if the starting power is not specified.
● The transformer does not change the frequency of the input supply.
Make sure the appliances can accept the same frequency of the input supply.
● Earth cable connection of the transformer and appliance must be secured.
7. PLACEMENT
● Place the transformer in a place where it's cool, dry and well ventilated.
● Place the transformer in a place where the children can't reach for.
● Do not place the transformer in or near water.
● Do not place transformer on an unstable cart, stand or table.
● Do not place transformer under direct sunlight, excessive humidity.
● Keep away from fire, heat sources.
● Keep away from corrosive gas or fluid.
● Do not place power cord in any area where it may get damaged by heavy objects.
The transformer can only be repaired by the authorized technical service
personnel. Any attempt to open and to repair by the user on his own
Placing magnetic storage media on top of the transformer may result in
Earth connections for the transformer and for all appliances connected
should be secured. Without earth connection or unproved earth
connections are dangerous for user's health, and have high
risk of electronic circuit board faults.
could prove to be dangerous.
