To prevent device damage and physical injury, please read carefully the safety recommendations
described in this chapter.
Recommendations do not cover all possible hazardous situations.

3.1 Grounding and Lightning Protection


Ensure that both the power-receiving end and the power-supplying end are well-grounded.

Keep the grounding connection within 30 m, and use a 40mm x 4mm or 50mm x 5mm ground bar of
hot-dip zinc-coated flat steel sheet.

When the connection cable between the main grounding conductor and local equipotential earthing
terminal board (LEB) on each floor is shorter than 2 meters, use a stranded copper wire with a
sectional area not less than 1.318 mm2 (16 AWG) for the connection cable.

Use a shielded network cable if possible, ensure that devices connected to both ends of the shielded
network cable are reliably grounded, and make sure that the sheath of the shielded network cable is
also grounded if possible. If no shielded network cable is available, wire the network cable through
a steel pipe and bury the steel pipe for lead-in, and properly ground both ends of the steel pipe.

No additional lightning protector is required as a high-profile lightning protector is built in the IGAP-
W99110GP+, and the power port support 6kV lightning protection. If a lightning protector of a higher
profile is available, configure the lightning protector optionally. Before the configuration, connect the
lightning protector to the ground cable.

Use a power cable with the PE end to ground the power supply (AC). Ensure that the PE end is
properly grounded, with a ground resistance less than 5 ohms. Do not use a two-wire power cable
with only the live (L) wire and naught (N) wire. Do not connect the N wire to the protection ground
cable of other communication devices, and ensure that the L wire and N wire are properly connected.

Ensure that the ground resistance is less than 5 ohms. In areas with high soil resistivity, reduce the
soil resistivity via measures such as spreading resistivity reduction mixture around the grounding
conductor.
