IMPORTANT DEFINITIONS
Electrostatic Discharge Awareness
All electronic equipment is electro static-sensitive, some components more
than others. To protect these components from electro static damage, you
must take special precautions to minimize or eliminate electrostatic
discharges.
Follow these precautions when working with or near the control.
1. Before doing maintenance on the electronic control, discharge the
static electricity on your body to ground by touching and holding a
grounded metal object (pipes, cabinets, equipment, etc.).
2. Avoid the build-up of static electricity on your body by not wearing
clothing made of synthetic materials. Wear cotton or cotton-blend
materials as much as possible because these do not store static
electric charges as much as synthetics.
3. Keep plastic, vinyl, and Styrofoam materials (such as plastic or
Styrofoam cups, cup holders, cigarette packages, cellophane
wrappers, vinyl books or folders, plastic bottles, and plastic ash trays)
away from the control, the modules, and the work area as much as
possible.
4. Do not remove any printed circuit board (PCB) from the control cabinet
unless absolutely necessary. If you must remove the PCB from the
control cabinet, follow these precautions:
•
Do not touch any part of the PCB except the edges.
•
Do not touch the electrical conductors, the connectors, or the
components with conductive devices or with your hands.
•
When replacing a PCB, keep the new PCB in the plastic
antistatic protective bag it comes in until you are ready to
install it. Immediately after removing the old PCB from the
control cabinet, place it in the antistatic protective bag.
To prevent damage to electronic components caused by improper
handling, read and observe the precautions in Woodward manual 82715,
Guide for Handling and Protection of Electronic Controls, Printed Circuit
Boards, and Modules.
