PRODUCT SAFETY NOTICE
- Many electrical and mechanical parts
have special safety-related characteristics some of which are often not
evident from visual inspection, nor can the protection they give neces-
sarily be obtained by replacing them with components rated for higher
voltage, wattage, etc. Parts that have special safety characteristics are
identified in BARCO service data by on schematics and in the parts
list. Use of a substitute replacement that does not have the same safety
characteristics as the recommended replacement part in BARCO
service data parts list might create shock, fire, and/or other
hazards. Product Safety is under review continuously and new
instructions are issued whenever appropriate. For the latest
information, always consult the appropriate current BARCO serv-
ice literature.
SERVICING PRECAUTIONS
CAUTION:
Before servicing instruments covered by this service data
and its supplements and addendums, read and follow the SAFETY
PRECAUTIONS of this publication.
NOTE: If unforeseen circumstances create conflict between the follow-
ing servicing precautions and any of the safety precautions on page 2
of this publication, always follow the safety precautions.
Remember: Safety First.
General Servicing Precautions
1. Always unplug the instrument AC power cord from the AC power
source before:
a. Removing or reinstalling any component, circuit board, module, or
any other instrument assembly.
b. Disconnecting or reconnecting any instrument electrical plug or other
electrical connection.
c. Connecting a test substitute in parallel with an electrolytic capacitor
in the instrument.
Caution: A wrong part substitution or incorrect polarity installation of
electrolytic capacitors may result in an explosion hazard.
2. Do not spray chemical on or near this instrument or any of its
assemblies.
3. Unless specified otherwise in this service data, clean electrical
contacts by applying the following mixture to the contacts with a pipe
cleaner, cotton-tipped stick or comparable nonabrasive applicator:
10% (by volume) Acetone and 90% (by volume) isopropyl alcohol
(90%-99% strength).
Caution:
This is a flammable mixture.
Unless specified otherwise in this service data, lubrication of contacts
is not required.
4. Do not defeat any plug/socket B+ voltage interlocks with which
instruments covered by this service data might be equipped.
5. Do not apply AC power to this apparatus and/or any of its electrical
assemblies unless all solid-state device heat sinks are correctly installed.
6. Always connect the test instrument ground lead to the appropriate
instrument chassis ground before connecting the test instrument positive
lead. Always remove the test instrument ground lead last.
7. Use with this instrument only the test fixtures specified in this service
data.
CAUTION:
Do not connect the test fixture ground strap to any heatsink
in this instrument.
Electrostatically Sensitive (ES) Devices
Some semiconductor (solid state) devices can be damaged easily
by static electricity. Such components commonly are called
Electrostatically Sensitive (ES) Devices. Examples of typical ES
devices are integrated circuits and some field-effect transistors
and semiconductor "chip" components. The following techniques
should be used to help reduce the incidence of component damage
caused by static electricity.
1. Immediately before handling any semiconductor component or
semiconductor-equipped assembly, drain off any electrostatic
charge on your body by touching a known earth ground. Wear
a commercially available high impedance discharging wrist strap
device.
2. After removing an electrical assembly equipped with ES devices,
place the assembly on a static dissipative surface such as a 3M
No 8210 table mat, to prevent electrostatic charge buildup or
exposure of the assembly.
3. Use only a grounded-tip soldering iron to solder or unsolder ES
devices.
4. Use only an anti-static type solder removal device. Some solder
removal devices not classified as "anti-static" can generate
electrical charges sufficient to damage ES devices.
5. Do not use freon-propelled chemicals. These can generate
electrical charges sufficient to damage ES devices.
6. Do not remove a replacement ES device from its protective
package until immediately before you are ready to install it. (Most
replacement ES devices are packaged with leads electrically
shorted together by conductive foam, aluminium foil or compa-
rable conductive material.)
7. Immediately before removing the protective material from the
leads of a replacement ES device, touch the protective material
to the chassis or circuit assembly into which the device will be
installed.
CAUTION:
Be sure no power is applied to the chassis or circuit,
and observe all other safety precautions.
8. Minimize bodily motions when handling unpackaged replace-
ment ES devices. (Otherwise harmless motion such as the
brushing together of your clothes fabric or the lifitng of your foot
from a carpeted floor can generate static electricity sufficient to
damage an ES device.)
