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

IMPORTANT NOTE : FCC RF Radiation Exposure
Statement
This equipment complies with FCC RF radiation
exposure limits set forth for an uncontrolled
environment. This equipment should be installed
and operated with a minimum distance of 20
centimeters between the radiator and your body.
This transmitter must not be co-located or operating
in conjunction with any other antenna or transmitter.

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.
