SAM4S SAP-630 SERIES 1-1

1 Precaution Statements

Follow these safety, servicing and ESD precautions to prevent damage and to protect against potential hazards

such as electrical shock.

1-1 Safety Precautions

1. Be sure that all built-in protective devices are

replaced. Restore any missing protective

shields.

2. When reinstalling the chassis and its

assemblies, be sure to restore all protective

devices, including nonmetallic control knobs and

compartment covers.

3. Make sure there are no cabinet openings

through which people - particularly children -

might insert fingers and contact dangerous

voltages. Such openings include excessively

wide cabinet ventilation slots and improperly

fitted covers and drawers.

4. Design Alteration Warning:

Never alter or add to the mechanical or

electrical design of the POS. Unauthorized

alterations might create a safety hazard. Also,

any design changes or additions will void the

manufacturer’s warranty.

5. Components, parts and wiring that appear to

have overheated or that are otherwise damaged

should be replaced with parts that meet the

original specifications. Always determine the

cause of damage or over- heating, and correct

any potential hazards.

6. Observe the original lead dress, especially near

the following areas : sharp edges, and

especially the AC and high voltage supplies.

Always inspect for pinched, out-of-place, or

frayed wiring. Do not change the spacing

between components and the printed circuit

board. Check the AC power cord for damage.

Make sure that leads and components do not

touch thermally hot parts.

7. Product Safety Notice:

Some electrical and mechanical parts have

special safety-related characteristics which

might not be obvious from visual inspection.

These safety features and the protection they

give might be lost if the replacement component

differs from the original - even if the

replacement is rated for higher voltage, wattage,

etc.

Components that are critical for safety are

indicated in the circuit diagram by shading,

() or ( ). Use replacement components

that have the same ratings, especially for

flame resistance and dielectric strength

specifications. A replacement part that does

not have the same safety characteristics as the

original might create shock, fire or other

hazards.

8. The socket-outlet shall be installed near

The equipment and shall be easily accessible

9. This device complies with part 15 of the FCC

Rules. Operation is subject to the following two

conditions:

(1) This device may not cause harmful interference,

and

(2) This device must accept any interference

received, including interference that may cause

undesired operation

10. This equipment has been tested and found to

comply with the limits for a Class A digital device,

pursuant to part 15 of the FCC Rules. These limits

are designed to provide reasonable protection

against harmful interference when the equipment is

operated in a commercial environment. This

equipment generates, uses, and can radiate radio

frequency energy and, if not installed and used in

accordance with the instruction manual, may cause

harmful interference to radio communications.

Operation of this equipment in a residential area is

likely to cause harmful interference in which case

the user will be required to correct the interference

at his own expense

1-2 Servicing Precautions

WARNING: First read the-Safety Precautions-section of this manual. If some unforeseen circumstance creates

a conflict between the servicing and safety precautions, always follow the safety precautions.

WARNING: An electrolytic capacitor installed with the wrong polarity might explode.

1. Servicing precautions are printed on the cabinet.

Follow them.

2. Always unplug the units AC power cord from the

AC power source before attempting to:

(a) Remove or reinstall any component or

assembly (b) Disconnect an electrical plug or

connector (c) Connect a test component in

parallel with an electrolytic capacitor

3. Some components are raised above the printed

circuit board for safety. An insulation tube or

tape is sometimes used. The internal wiring is

sometimes clamped to prevent contact with

thermally hot components. Reinstall all such

elements to their original position.

4. After servicing, always check that the screws,

components and wiring have been correctly

reinstalled. Make sure that the portion around the

serviced part has not been damaged.

5. Check the insulation between the blades of the

AC plug and accessible conductive parts

(examples : metal panels and input terminals).

6. Insulation Checking Procedure:

Disconnect the power cord from the AC source

and turn the power switch ON. Connect an

insulation resistance meter (500V) to the blades

of AC plug.

The insulation resistance between each blade of

the AC plug and accessible conductive parts

(see above) should be greater than 1 megaohm.

7. Never defeat any of the B+ voltage interlocks.

Do not apply AC power to the unit (or any of its

assemblies) unless all solid-state heat sinks are

correctly installed.

8. Always connect an instrument’s ground lead to

the instrument chassis ground before connecting

the positive lead ; always remove the

instrument’s ground lead last.

1-3 Precautions for Electrostatically Sensitive Devices (ESDs)

1. Some semiconductor (solid state) devices are easily

damaged by static electricity. Such components are

called Electrostatically Sensitive Devices (ESDs);

examples include integrated circuits and some field-

effect transistors. The following techniques will reduce

the occurrence of component damage caused by static

electricity.

2. Immediately before handling any semiconductor

components or assemblies, drain the electrostatic

charge from your body by touching a known earth

ground. Alternatively, wear a discharging wrist-strap

device. (Be sure to remove it prior to applying power -

this is an electric shock precaution.)

3. After removing an ESD-equipped assembly, place it

on a conductive surface such as aluminum foil to

prevent accumulation of electrostatic charge.

4. Do not use freon-propelled chemicals. These can

generate electrical charges that damage ESDs.

5. Use only a grounded-tip soldering iron when soldering

or unsoldering ESDs.

6. Use only an anti-static solder removal device. Many

solder removal devices are not rated as anti-static;

these can accumulate sufficient electrical charge to

damage ESDs.

7. Do not remove a replacement ESD from its protective

package until you are ready to install it. Most

replacement ESDs are packaged with leads that are

electrically shorted together by conductive foam,

aluminum foil or other conductive materials.

8. Immediately before removing the protective material

from the leads of a replacement ESD, touch the

protective material to the chassis or circuit assembly

into which the device will be installed.

9. Minimize body motions when handling unpackaged

replacement ESDs. Motions such as brushing clothes

together, or lifting a foot from a carpeted floor can

generate enough static electricity to damage an ESD.
