(2) Grounding
(a) Where possible, ground the PT-E independently.
The grounding work is class D grounding (grounding resistance 100 Ω or less)
(b) When independent grounding is impossible, use the joint grounding method marked (2) below.
Figure 4.9 Grounding method
(c) The size of grounding wires must be 2 mm

or more.
Use wire in which green and yellow color is combined for grounding wire.
The grounding point should be as near as possible to PT-E to minimize grounding cable length.
CAUTION
Do class D or higher grounding work to earth PT-E. In addition, do not share the grounding with
other equipment.
