2.6 Ground Cable Installation
The Kona Enterprise Gateway is considered Permanently Connected Equipment and requires a
permanently connected Protective Earth Ground (PEG) conductor. The Protective Earth Ground
connection is made through a M4/#8 on center hole lug with 10mm maximum OD to the ground
termination point illustrated in Figure 9. The recommended ground cable gauge is #10 AWG. The
Kona Enterprise Gateway grounding system shall follow local and national electrical codes. The
Protective Earth Ground conductor terminated at the hole lug point is mandatory and must be
the first connection made to the Kona Enterprise Gateway during installation. Proper routing and
termination of this cable is key to robust lightning withstand performance; in high susceptibility
installations, every effort shall be made to minimize connection inductance and ground bed
resistance. The ground cable installation steps are as follows:
1. Lightly abrade the surface of the casting ground area with a fine wire brush to remove the
oxide layer.
2. Use a clean cloth to remove any debris from this surface.
3. Immediately coat the contact surface with a thin layer of anti-oxidant compound.
4. Install the ground cable through its single hole lug onto the chassis ground point using the
supplied M4x0.7 – 12mm bolt with flat, lock, and star washers, torqued to 2.4Nm (22
in·lbs).
