Notes on Use

8

• Connect the module to a power source that

matches the rating in order to prevent fire.

• Ensure that the power supply, input, and output

are correctly wired according to the wiring dia-
gram. (See the chapter on "Preparations" in the
instructions manual for each module.) This will
prevent fire, malfunction, and errors.

• Use cables of the proper sizes for the rated cur-

rent. This will prevent entire system errors and
fire resulting from broken wire.

• Use crimp connectors suitable for the cable

sizes. This will prevent module errors and fire
due to broken wires.

• If power supply noise poses a problem, use of a

noise filter is recommended.

• When the power and signal lines may be subject

to a lightning-induced surge, install a lightning
arrester between another instrument or module
connected to this module and line to protect the
system.

• Avoid stepping on or pinching cables, which

could damage the cable insulation.

• Keep the cables well away from heat sources,

as bare conductors could be exposed if the
insulation melts.
