• The End Cover has a metal portion and is heavier than it looks. Be careful not to drop it when han-
dling.
Installation
• Always connect to a ground of 100 Ω or less when installing the Units.
Wiring
• Follow the instructions in this manual to correctly perform wiring.
Double-check all wiring and switch settings before turning ON the power supply.
• Use the methods that are specified in this manual for wiring the terminal blocks.
• Use crimp terminals for wiring the M3 screw terminal blocks. Do not connect bare stranded wires
directly to the M3 screw terminal blocks.
• Use the correct wiring parts and tools when you wire the system. Otherwise, cables may be discon-
nected to cause short-circuit or wire breakage.
• Do not pull on the cables or bend the cables beyond their natural limit.
Do not place heavy objects on top of the cables or other wiring lines. Doing so may break the ca-
bles.
• Mount terminal blocks, connectors, and Option Boards only after checking the mounting location
carefully.
• Be sure that the terminal blocks, communications cables, and Option Boards with tightening screws
or locking devices are properly tightened to or locked into place.
• If the external power supply to a built-in output, Output Unit or slave has polarity, connect it with the
correct polarity. If the polarity is reversed, current may flow in the reverse direction and damage the
connected devices regardless of the operation of the Controller.
• When you insert a flat-blade screwdriver into a release hole on a screwless clamping terminal block
of CPU Unit, press it down with a force of 30N or less. Applying excessive force may damage the
terminal block.
• Do not incline or twist the flat-blade screwdriver while it is in a release hole on a screwless clamping
terminal block of CPU Unit. Doing so may damage the terminal block.
