3.2.1
Cautions
1) Make sure to short-circuit the 'V +' and 'VI-' terminals when ch is not used.
2) Use 2-core shielded twisted pair cable for the analog input lines, and
separate the analog input lines from other power lines or inductive lines.
3) The grounding resistance should be 100 Ω or less.
3.3 Grounding
Grounding should be performed as stated below.
• The grounding resistance should be 100 Ω or less.
• Independent grounding should be performed for best results.
When independent grounding is not performed, perform "shared grounding" of
the following figure.
For details, refer to the following manual.

• The grounding wire size should be AWG 22-20 (0.3-0.5 mm
).
• The grounding point should be close to the PLC, and all grounding wire should
be as short as possible.

STARTUP AND
MAINTENANCE
PRECAUTIONS
• Do not disassemble or modify the PLC.
Doing so may cause fire, equipment failures, or malfunctions.
* For repair, contact your local Mitsubishi Electric representative.
• Do not drop the product or exert strong impact to it.
Doing so may cause damage.
DISPOSAL
PRECAUTIONS
• Please contact a certified electronic waste disposal company for the
environmentally safe recycling and disposal of your device.
TRANSPORTATION AND
STORAGE PRECAUTIONS
• The product is a precision instrument. During transportation, avoid impacts larger
than those specified in the general specifications by using dedicated packaging
boxes and shock-absorbing palettes. Failure to do so may cause failures in the
product. After transportation, verify operation of the product and check for
damage of the mounting part, etc.
