1.3.1 Identifying ESDS Components
Below are some industry symbols used to label components as ESDS:
1.3.2 Handling ESDS Components
Observe all precautions necessary to prevent damage to ESDS components
before installation. Bring the device and everything that contacts it to ground
potential by providing a conductive surface and discharge paths. At a
minimum, observe these precautions:
1.
De-energize or disconnect all power and signal sources and loads used
with unit.
2.
Place unit on a grounded conductive work surface.
3.
Ground technician through a conductive wrist strap (or other device)
using 1 M series resistor to protect operator.
4.
Ground any tools, such as soldering equipment, that will contact unit.
Contact with operator's hands provides a sufficient ground for tools that
are otherwise electrically isolated.
5.
Place ESDS devices and assemblies removed from a unit on a
conductive work surface or in a conductive container. An operator
inserting or removing a device or assembly from a container must
maintain contact with a conductive portion of the container. Use only
plastic bags approved for storage of ESD material.
6.
Do not handle ESDS devices unnecessarily or remove from the
packages until actually used or tested.
1.4 SAFETY SUMMARY
Observe these general safety precautions during all phases of instrument
operation, service, and repair. Failure to comply with these precautions or
with specific warnings elsewhere in this manual violates safety standards of
design, manufacture, and intended instrument use. OMEGA assumes no
liability for Customer failure to comply with these requirements.
Ground The Instrument
To minimize shock hazard, connect instrument chassis and cabinet to an
electrical ground. The instrument comes with a 3-conductor AC power
cable. Plug it into an approved three-contact electrical outlet or use a three-
contact adapter with the green ground wire firmly secured to an electrical
ground (safety ground) at the power outlet. The power cable jack and
mating plug meet Underwriters Laboratories (UL) and International
Electrotechnical Commission (IEC) safety standards.
