6. Attach an ESD grounding strap to your bare wrist and connect the strap to one of the
ESD points on the chassis.
7. Place the grounding cable lug over the grounding points on the front of the chassis
(see Figure 26 on page 115).
8. Secure the grounding cable lug with the washers and screws. The holes are sized for
SAE 10-32 screws. Apply 4.34 lb-in. (0.49 Nm) of torque to each screw. Do not
overtighten the screw. (Use a number 2 Phillips screwdriver.)
CAUTION: Ensure that each grounding cable lug seats flush against the
surface of the grounding points as you are tightening the screws. Ensure
that each screw is properly threaded into the grounding points. Applying
installation torque to the screw when it is improperly threaded may
damage the terminal.
CAUTION: The maximum torque rating of the grounding screws on the
router is 4.34 lb-in. (0.49 Nm). The grounding screws may be damaged if
excessive torque is applied. Use only a torque-controlled driver to tighten
screws. Use an appropriately sized driver, with a maximum torquecapacity
of 5 lb-in. or less. Ensure that the driver is undamaged and properly
calibrated and that you have been trained in its use. You may wish to use
a driver that is designed to prevent overtorque when the preset torque
level is achieved.
9. Dress the grounding cable, and verify that it does not touch or block access to router
components, and that it does not drape where people could trip on it.
