4-3 Wiring the Terminals
This section provides information on wiring the terminals on Position Interface Units.
This section describes wiring the screwless clamping terminal blocks, terminal block mounting and
removal methods, and prevention of incorrect attachment.
You can connect ferrules that are attached to twisted wires to the screwless clamping terminal block.
You can also connect twisted wires or solid wires to the screwless clamping terminal block. If you con-
nect ferrules, all you need to do to connect the wires is to insert the ferrules into the terminal holes.
Precautions for Safe Use
• Do not insert a flat-blade screwdriver straight into the release hole. Doing so may damage
the terminal block.
• When you insert a flat-blade screwdriver into a release hole, press it down with a force of
30 N or less. Applying excessive force may damage the terminal block.
• Do not tilt or twist the flat-blade screwdriver while it is pressed into the release hole. Doing
so may damage the terminal block.
• Double-check all wiring to make sure that it is correct before turning ON the power supply.
Use the correct wiring parts and tools when you wire the system.
• Do not pull on the cables or bend the cables beyond their natural limit. Also, do not place
heavy objects on top of the cables or other wiring lines. Doing so may break the cable.
Make sure that the voltages and currents that are input to the Units and slaves are within
the specified ranges.
Inputting voltages or currents that are outside of the specified ranges may cause accidents
or fire.
