Grounding

This equipment must be earthed.

An independent earth pole shall be used for Control Terminal.

(Earth construction is the class-3 grounding. The level of

grounding resistance should be less than 100 Ω.)

Use a cable which has a nominal cross section of more than

2mm

for grounding.

Grounding point shall be near the Control Terminal to shorten

the distance of grounding wires.

When the unit is grounded along with other machines, or is

grounded to a part of a building, it can be adversely affected.

If any input-output errors occur due to the grounding, detach the

FG terminal from the ground.

Wiring for communication

Never place the communication cable

with electric circuits.

Never bundle these cables together with

other wires in ducts or electric boxes

using cord locks. Although it is tempting

to bundle all the cables neatly together,

this does not necessarily lead to a noise-

resistant configuration.

It is recommended that the communica-

tion cable be independently wired.
