Grounding Cable Lug Specifications
The grounding cable lug is used to secure the grounding cable to the grounding points on the ACX
chassis. The grounding cable lug attaches to the grounding cable (see
secured to the router by two 0.5-inch-long SAE 10–32 screws. We recommend using paint-piercing
washers between the grounding lug and the screws. The grounding cable lug, screws, and washers are
not supplied with the router.
Figure 17: Grounding Cable Lug
CAUTION: Before you install the router, a licensed electrician must attach a cable lug to
the grounding and power cables that you supply. A cable with an incorrectly attached
lug can damage the router.
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 torque capacity 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.
Grounding Cable Specifications
You must provide one grounding cable that meets the following specifications: 6-AWG (4.11 mm
minimum 90°C wire, or as required by the local code.
