10 Maintenance and behaviour in case of failure
KS 816 requires no special maintenance and does not contain parts which require
preventive maintenance or care.
10.1 Cleaning
If necessary, the aluminium and plastics parts must be cleaned carefully with spirit.
Do not use agents which contain solvents or scouring powder.
10.2 Trouble-shooting
To start with, all possibilities of error in other equipment and connections (input
leads, cables, equipment connected in the output circuit) should be examined.
If the error cannot be located with the hints given in this section, we recommend
returning the unit to the manufacturer.

If the trouble is due to failure of a fuse, the cause must be determined and remo-
ved. The spare fuse must be of the same rating as the original type.
If the PWR LED is not lit despite correct supply voltage polarity, KS 816 is defective
and must be returned to the manufacturer for repair.
Before disconnecting the unit, switch off the power supply of the installation and
check that other equipment in the installation is not affected.
WARNING!
When safe operation seems not possible any more, shut down the unit and
protect it against accidental switch-on.
For dismounting the unit, see section 3.2
