3) Connecting a cable
• When ferrules with insulation sleeve are used
Insert a wire with the ferrule with insulation sleeve into the wire insertion
opening and push the wire.
• When stranded wires and solid wires are used
Push the open/close button of the terminal block with a flathead
screwdriver. While pushing the open/close button, insert the wire into the
insertion opening until the wire reaches the back, and then release the
open/close button.
Then, pull the wire lightly and check that it is clamped securely.

4) Disconnecting a cable
Push the open/close button of the wire to be disconnected with a flathead
screwdriver. Pull out the wire with the open/close button pushed.

low, use a wire without a resistance difference between the lead wire.

3.3 Grounding
Ground the PLC as stated below.
• Perform class D grounding. (Grounding resistance: 100 Ω or less)
• Ground the PLC independently if possible.
If the PLC cannot be grounded independently, perform the "Shared grounding"
shown below.
For details, refer to the following manual.

4. Specification
DESIGN
PRECAUTIONS
• Make sure to set up the following safety circuits outside the PLC to ensure safe
system operation even during external power supply problems or PLC failure.
Otherwise, malfunctions may cause serious accidents.
- Most importantly, set up the following: an emergency stop circuit, a protection
circuit, an interlock circuit for opposite movements (such as normal vs. reverse
rotation), and an interlock circuit (to prevent damage to the equipment at the
upper and lower positioning limits).
- Note that when the CPU module detects an error, such as a watchdog timer
error, during self-diagnosis, all outputs are turned off. Also, when an error that
cannot be detected by the CPU module occurs in an input/output control block,
output control may be disabled.
External circuits and mechanisms should be designed to ensure safe
machinery operation in such a case.
- Note that when an error occurs in a relay, transistor or triac of an output circuit,
the output might stay on or off.
For output signals that may lead to serious accidents, external circuits and
mechanisms should be designed to ensure safe machinery operation in such a case.
DESIGN
PRECAUTIONS
• Simultaneously turn on and off the power supplies of the CPU module and
extension modules.
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
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.
