Omron FQM1-CM001 사용자 설명서

• LG is a noise-filtered neutral terminal. If noise is a significant source of

errors and to prevent electrical shocks, connect the line ground terminal
to the ground terminal and ground both with a ground resistance of less
than 100 

Ω or less.

• If connecting the line ground and ground terminals, always ground both to

less than 100 

Ω to prevent electrical shock.

• The ground wire should not be more than 20 m long.

• The FQM1 is designed to be mounted so that it is isolated (separated)

from the mounting surface to protect it from the effects of noise in the
installation environment (e.g., the control panel).

• Do not share the FQM1's ground with other equipment or ground the

FQM1 to the metal structure of a building. Doing so may worsen opera-
tion.
