Step 3: Ground the ACX2200 Router
You must ground DC-powered routers before connecting DC power.
Tools Required to Ground the ACX Router
To ground the router, you need the following tools:
Phillips (+) screwdriver, number 2
ESD grounding wrist strap
Two SAE 10-32 screws and flat washers (not provided)
Grounding lug, Panduit LCD6-14BH-L or equivalent (not provided)
Grounding cable, use 16-AWG (1.31 mm2) 90° C wire for AC systems (not provided)
Connect the Grounding Cable
You ground the router by connecting a grounding cable to earth ground and then attaching it to the chassis grounding points. To ground the router:
- Verify that a licensed electrician has attached the cable lug, which is provided with the router, to the grounding cable.
- Attach an ESD grounding strap to your bare wrist, and connect the other end of the strap to an approved site ESD grounding point. See the instructions for your site.
- Ensure that all grounding surfaces are clean and brought to a bright finish before you make grounding connections.
- Connect the grounding cable to a proper earth ground.
- Detach the ESD grounding strap from the site ESD grounding point.
- Attach an ESD grounding strap to your bare wrist, and connect the other end of the strap to an ESD grounding point.
- Place the grounding cable lug over the grounding points on the front of the chassis (see Figure 1).
- Secure the grounding cable lug with the washers and screws. The holes are sized for SAE 10-32 screws.
- 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.
