1 Safety Precaution

1.1. General Guidelines

1. IMPORTANT SAFETY NOTICE

There are special components used in this equipment

which are important for safety. These parts are marked by

1.3. Leakage Current Hot Check

(See Figure 1.)

1. Plug the AC cord directly into the AC outlet. Do not use

an isolation transformer for this check.

2. Connect a 1.5 k Ω , 10 W resistor, in parallel with a 0.15 μ F

capacitor, between each exposed metallic part on the set

and a good earth ground, as shown in Figure 1.

3. Use an AC voltmeter, with 1 k Ω /V or more sensitivity, to

measure the potential across the resistor.

4. Check each exposed metallic part, and measure the volt-

age at each point.

5. Reverse the AC plug in the AC outlet and repeat each of

the above measurements.

6. The potential at any point should not exceed 0.75 V RMS.

A leakage current tester (Simpson Model 229 or equiva-

lent) may be used to make the hot checks, leakage cur-

rent must not exceed 1/2 mA. In case a measurement is

outside of the limits specified, there is a possibility of a

shock hazard, and the equipment should be repaired and

rechecked before it is returned to the customer.

in the Schematic Diagrams, Circuit Board Layout,

Exploded Views and Replacement Parts List. It is essen-

tial that these critical parts should be replaced with manu-

facturer’s specified parts to prevent X-RADIATION,

shock, fire, or other hazards. Do not modify the original

design without permission of manufacturer.

2. An Isolation Transformer should always be used during

the servicing of AC Adaptor whose chassis is not isolated

from the AC power line. Use a transformer of adequate

power rating as this protects the technician from acci-

dents resulting in personal injury from electrical shocks. It

will also protect AC Adaptor from being damaged by acci-

dental shorting that may occur during servicing.

3. When servicing, observe the original lead dress. If a short

circuit is found, replace all parts which have been over-

heated or damaged by the short circuit.

4. After servicing, see to it that all the protective devices

such as insulation barriers, insulation papers shields are

properly installed.

5. After servicing, make the following leakage current

checks to prevent the customer from being exposed to

shock hazards.

1.2. Leakage Current Cold Check

1. Unplug the AC cord and connect a jumper between the

two prongs on the plug.

2. Measure the resistance value, with an ohmmeter,

between the jumpered AC plug and each exposed metal-

lic cabinet part on the equipment such as screwheads,

connectors, control shafts, etc. When the exposed metal-

lic part has a return path to the chassis, the reading

should be between 1 M Ω and 5.2 M Ω . When the exposed

metal does not have a return path to the chassis, the

reading must be infinity.

1.4. How to Discharge the Capacitor on Power/Top PCB

CAUTION:

1. Be sure to discharge the capacitor on POWER/TOP PCB.

2. Be careful of the high voltage circuit on POWER/TOP PCB when servicing.

[Discharging Procedure]

1. Refer to the disassemble procedure and Remove the necessary parts/unit.

2. Put the insulation tube onto the lead part of Resistor (ERG5SJ102:1k Ω /5W).

(an equivalent type of resistor may be used.)

3. Put the resistor between both terminals of capacitor on POWER/TOP PCB for approx. 5 seconds.

4. After discharging confirm that the capacitor voltage is lower than 10V using a voltmeter.

2Warning

2.1. Prevention of Electro Static Discharge (ESD) to Electrostatically

Sensitive (ES) Devices

Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Elec-

trostatically Sensitive (ES) Devices.

The following techniques should be used to help reduce the incidence of component damage caused by electro static discharge

(ESD).

1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any ESD on your

body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging ESD wrist strap,

which should be removed for potential shock reasons prior to applying power to the unit under test.

2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as alumi-

num foil, 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 antistatic solder removal device. Some solder removal devices not classified as "antistatic (ESD protected)" can

generate electrical charge 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, aluminum foil or compara-

ble 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 replacement ES devices. (Otherwise harmless motion such as the

brushing together of your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity (ESD) suf-

ficient to damage an ES device).
