Mortal danger from electric shock
Exposed power contacts - High Voltage
Fig. 20: Draft high frequency generator (1-4-4 + 1-4-5S)
The causes:
– The screws (1) are not tightened properly, or not all 22 of them are
screwed in.
– The cap nuts (2) are not tightened properly or not all 14 are in place.
– The cover (3) does not seal tightly with the plates (4) and (5) or with the
contract straps behind it, on the front panel (6)
– One or both filters (7) are not OK
– The filter (11) can also be damaged in this way.
– When the ground strip (12) is not connected after removal or replacement
of the oscillator the filters (7) will defect.
– The capacitor (9) is out of order
– The capacitor (10) is out of order. This is however less likely.
In case of failure of this capacitor, most probably the fuses blow.
