5.23.5 Output protection
The power amplifier is of short circuit protection function and over heat protection.
Usually it is unable to be destroyed but long time output short circuit should be avoided.
The frequency, amplitude and loading should be best within the limitation, two of which,
especially, cannot get the limitation at the same time in case that the power amplifier is
damaged.
6. Maintenance & fuse replacement
In the case of an electrical defect the melting fuse on the rear side (6) of the
device may trigger.
If this is the case, use only a fuse with the same ratings (T 3A/250V 5x20mm) for
replacement.
In normal operation mode the fuse should never trigger without any reasons, so
make sure the electrical defect is eliminated before restarting the device.
Note: The repair must be performed only by qualified personnel.
