Section 2. Safety Static Precautions
Static Precautions Electronic circuit boards can contain Electrostatic Discharge Sensitive (ESDS) devices. Static charges can accumulate from normal operation of the lift truck as well as movement or contact between non-conductive materials (plastic bags, synthetic clothing, synthetic soles on shoes, Styrofoam coffee cups, and so forth.) Accumulated static electricity can be discharged to a circuit board or component by touching the parts. Electrostatic Discharge (ESD) is also possible through the air when a charged object is placed close to another surface at a different electrical potential. Static discharge can occur without seeing or feeling it.
•
If you are removing or installing static-sensitive components, place them on a correctly grounded anti-static mat.
•
To transport static sensitive components, including failed components being returned, place the components in an anti-static bag or box (available from your local authorized Raymond Sales and Service Center).
Test the wrist strap and related accessories before each use to make sure they are working correctly. Figure 2-2 shows the components of the Raymond anti-static field service kit, P/N 1-187-059. The kit includes a wrist strap, ground cord, and static-dissipative work surface (mat). Follow the instructions packaged with the kit.
Whenever working on or near ESDS devices, follow these precautions. •
Wear an ESD wrist strap. The wrist strap should be equipped with a 1 megohm resistor to dissipate static charges slowly.
•
Connect the wrist strap plug to the ground jack on the lift truck. See Figure 2-1. If you cannot use the ground jack, connect the ground clip to an unpainted, grounded surface on the lift truck frame.
Figure 2-2.
