10.1 AC Input, DC Power, And Ground Cables
1. For AC input cable, VCT (Polyvinyl Chloride Cabtyre Cable) is to be used. However, if shielding is nec-
essary, as is the case when the AC input cable is to be installed in parallel with a low-voltage power cable,
etc., be sure to use VCT-S (Shielded Polyvinyl Chloride Cabtyre Cable).
2. For the power receiving terminals of the PBX, -48 V and G terminals are provided in dual (A side and B
side). For...
