SAFETY PRECAUTIONS
GENERAL GUIDELINES
1.
it is advisable to insert an isolation transformer in the
power line and AC supply before servicing a hot chassis.
. When servicing, observe the original lead dress, especially
the lead dress in the high voltage circuits. If a short
Circuit is found, replace all parts which have been
overheated or darnaged by the short circuit.
. After servicing, see to it that all the protective devices
such as insulation barriers, insulation papers, shields, and
isolation C-R combinations, are properly installed.
. Before turning the monitor on, measure the resistance
between B+ fine and chassis ground. Connect © side of
an ohmmeter to the B+ lines, and @_ side to chassis
ground. Each line should have more resistance than
specified, as follows:
B+ Line Minimum Resistance
_ When the monitor is not to be used fora long period of
time, unplug the power cord from the AC outlet.
. Potentials, as high as 23.5 kV are present when this
monitor is in operation. Operation of the monitor
without the rear cover involves the danger of a shock
hazard from the monitor power supply. Servicing
should not be attempted by anyone who is not
thoroughly familiar with the precautions necessary when
working on high voltage equipment. Always discharge
the anode of the picture tube to the monitor chassis
before handling the tube.
. After servicing, make the following leakage current
checks to prevent the customer from being eves to
shock hazards. |
