Protection devices
The DDA4-1000 includes a protection component against
momentary over voltages. But continuous overvoltage, which is an
indicator for a faulty mains supply, causes overheating of this
component.
To prevent damage to the DDA4-1000 by overheating and then by
over voltage, there is a thermo-fuse witch cuts off the power supply.
If this happens, the temperature fuse must be replaced, either by us
or by an electrician.
In addition, the DDA4-1000 has a 5x20mm ceramic body cartridge
fuse, fast blow, 5Amp (with high breaking capacity 1500A)
The use of the cheaper glass tubes is not permitted (to low breaking
capacity).
