Ground cable connections
1. Cut the ground cable into a proper length and use the M4 OT terminal to connect to the
AP. The OT terminal used to connect to the ground terminal depends on site requirements.
NOTE
To tighten the screws with a torque on the ground bar,
l M4: 1.4N•m.
l M6: 4.8N•m.
l M8: 12N•m.
2. The equipment functions properly when the ground resistance is less than 10 ohms.
Grounding shielded network cables
Using shielded network cables can improve surge protection performance of the AP. To connect
the cable, cut the shield layer open, connect the cable to the ground clip, and wrap the cable with
waterproof and ESD tapes.
1. Determine the position for installing the ground clip on the cable based on the actual cable
route.
2. Use a utility knife to strip the sheath off the network cable for about 32 mm (1.26in.) to
expose the shield layer.
NOTICE
Do not damage the shield layer when stripping the sheath off the cable.
