safety equipments, health of persons in vicinity, e.g. at the cardiac stimulators use
etc.
The source must be disconnected from mains by unplugging the fork of the supply
cable at any manipulation with the source (change of the standing place, removing of
the covers at a regular inspectionD).
3.7. Duties of operator before beginning work
Before beginning work with the source the operator is obligated:
- to study these operating instructions
-
to check: the supply cable (the insulation must not be damaged, the cable must
be firmly fixed in the source and in the fork).
The exchange of the damaged cable must be made by a worker with a
corresponding electro-technical qualification.
-
the welding cables (the insulation of the cables and electrode holder must not be
damaged).
In case of damage of the insulation of the cables and electrode holder, it is
necessary to change them.
3.8. Duties of the source provider (owner)
The source owner is obligated:
- to familiarize with these operating instructions
- to ensure immediate removal of failures and defects reported by the source
operator
- to ensure regular inspections of the source
- to ensure regular revisions of the source in terms of ČSN 33 1500 and ČSN
EN 05 0630
3.9. Regular inspections
The aim of the inspection is to ensure failure-free operation of the source.
The inspection term is given with regard to frequency of use and environment in
which the source works.
The inspection is carried out by a person with a corresponding electro-technical
qualification.
The inspection does not replace the revision!!
Prior to carrying out of the inspection, the source must be disconnected from mains
by unplugging the cable fork.
The inspection consists from the following steps:
- remove the covers of the source
- clean with the pressure air
- check the position of the conductors and state of electrical connections
(repair the damaged ones)
- check to fixation of the cable in the machine and in the fork
- measure continuity of perimeter of the protective conductor
Measurement of continuity of the protective circuit:
- connect the source output PELV to protective contact of the fork of the main
cable and to the farthest part of the cover where danger voltage may occur.
