1. Precaution Segment
1-1 Safety Precautions
1. Be sure that all of the 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 that 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. Leakage Current Hot Check:
WARING: Do not use an isolation transformer during this test.
Use a leakage-current tester or a metering system that complies with American National Standards
Institute (ANSI C101.1, Leakage Current for Applications), and Underwriters Laboratories (UL Publications
UL1410, 59.7).
With the unit completely reassembled, plug the AC line cord directly into a 100VAC or 240VAC outlet of the
Adaptor.
With the unit’s AC switch first in the ON position and then OFF, measure the current between a
known Earth ground (metal water pipe, conduit, etc.) and all exposed metal part, including: metal cabinet,
frame, and screw-heads and printer. The current measure should not exceed 0.1 milliamp. Reverse the
power-plug prong in the AC outlet and repeat the test.
5. Design Alteration Warning:
Never alter or add to the mechanical or electrical design of the ECR. Unauthorized alterations might create
a safety hazard. Also any design changes or additions will void the manufacture’s warranty.
6. Components, parts and wiring that appear to have overhead or that are otherwise damaged should be
replaced with parts that meet the original specifications. Always determine the cause of damaged or
overheating and correct any potential hazards.
7. 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.
8. 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.
