4 Connect and Manage cables
4.1 Fitting the Protection earth cable
4.1.1 There is an option to connect an earthing cable to the M6 screw fixing point at the
bottom of the main body casting. This should be connected to a protection ground bar or
clamped directly to the steel structure of the power or pole. This is required in areas of high
lightning activity or when the AirSynergy unit is mounted on high exposed roofs or tower
structures. A direct earth connection is required for the surge protection devices inside the
AirSynergy to be effective.

4.1.2 Connect the earth cable to the protection earth bar using suitable crimp lugs.
Alternatively use a clamp to join the earth cable to the steel structure of the mounting pole or
tower structure.
