ANNEX B. Installing Feeder CableB-8 © SAMSUNG Electronics Co., Ltd.B.3 Tower Ground Construction1) Install a Tower Ground Bar (TGB) that will be used to ground a feeder cable onto thetower. If the height of the tower is exceeds 20 m (65.62 ft), two or more TGBs shouldbe installed (onto the lower and upper sections of the tower). If the tower is 20 m(65.62 ft) or less, one TGB should be installed. Since the TGB installation location andthe number of TGBs to be installed can differ depending on the system environmentand provider’s standards, consult your service provider.2) Each TGB should be grounded and separated from other grounds. If there is anexisting ground bar or ground cable for TGB, install the TGB by branching from itusing a ground cable (AWG 1, GV 35 mm2 × 1C) ground cable. (However, thespecification of TGB ground cable can be different, defending on the standard ofservice provider.)3) Tighten the ground kit (feeder cable grounding assembly) to the TGB ground terminaland the tower hole using the pressure terminal hole attached at the end of the groundkit’s ground cable.
