Safety Precautions
Warning Indications
• Do not drop the Terminal Block.
Terminal Block functionality may be inhibited.
• Do not exceed the ratings. Doing so may damage or burn out the
Terminal Block.
• Mount the Terminal Blocks on a DIN Track and secure both ends
with Stoppers.
• Do not use the Terminal Block in locations where toxic gases, such
as H
2
S, SO
2
, NH
3
, HNO
3
, and Cl
2
, may be present, or in locations
subject to high temperature or humidity. Doing so may damage the
Terminal Block due to contact failure or corrosion.
• Do not use the Terminal Block submersed in oil or water, or in
locations continuously subject to splashes of oil or water. Doing so
may result in oil or water entering and damaging the Terminal
Block.
• Do not use or keep the Terminal Block under the following
conditions:
• Subject to severe temperature changes.
• Subject to high humidity or condensation.
• Subject to severe vibration or shock.
• Where direct rays of the sun strike.
• Where sea breeze may be present.
• Do not wire anything to the release holes.
• Do not tilt or twist a flat-blade screwdriver while it is inserted into a
release hole on the terminal block. The terminal block may be
damaged.
• Insert a flat-blade screwdriver into the release holes at an angle.
The terminal block may be damaged if you insert the screwdriver
straight in.
• Do not allow the flat-blade screwdriver to fall out while it is inserted
into a release hole.
• Do not bend a wire past its natural bending radius or pull on it with
excessive force.
Doing so may cause the wire disconnection. Do not place
excessive force on a Terminal Block. Doing so may damage or
deform the Terminal Block and result in contact failure.
• Do not insert more than one wire into each terminal insertion hole.
• If you mount more than one Terminal Block, mount them so that the
conductive parts of adjacent Terminal Blocks are facing in the
same direction. If they face in different directions, short circuits
may occur between adjacent Terminal Blocks.
• To prevent wire materials from smoking or igniting, confirm wire
ratings and use the wiring materials given in the following table.
1. Precautions for Correct Use
• Always mount End Covers to the following locations when you use
Terminal Blocks.
• Exposed metal surface of the last Terminal Block
• Any Terminal Block that is next to a different shape of Terminal
Block
There is a risk of electric shock if End Covers are not used.
• When you wire the Terminal Block, do not subject it or the wires to
stress. Secure the wires so that they do not resonate with
vibrations from the facilities in installation conditions.
• Always turn OFF the power supply before wiring. Electrical shock
may occur.
2. Connecting Wires to the Push-In Plus Terminal
Block
Part Names of the Terminal Block
Connecting Wires with Ferrules and Solid Wires
Insert the solid wire or ferrule straight into the terminal block until the
end strikes the terminal block.
If a wire is difficult to connect because it is too thin, use a flat-blade
screwdriver in the same way as when connecting stranded wire.
