!
CAUTION
Doing so may occasionally result in minor injury due
to electric shock. Do not touch the Relay while the
power supply is ON, except for the adjustment knob.
There is a risk of minor electrical shock, fire, or device
failure. Do not allow any pieces of metal, conductors, or
cutting chips that occur during the installation process to
enter the product.
Explosions may cause minor injuries. Do not use the
product in locations with inflammable or explosive
gases.
There is a risk of minor electrical shock, fire, or device
failure. Do not disassemble, modify, repair, or touch
the inside of the product.
Use of the product beyond its life may result in
contact welding or burning. Make sure to consider the
actual operating conditions and use the product
within its rated load and electrical life count. The life
of the output relay varies significantly with the switching
capacity and switching conditions.
If the Relay is used with incorrect wiring, fire may
occasionally occur, possibly resulting in physical
damage. Check the wiring for mistakes before you
turn ON the power supply.
If the Relay fails, monitoring and alarm outputs may
fail to operate. This may result in physical damage to
the facilities, equipment, or other devices that are
connected to it. To reduce this risk, inspect the Relay
regularly. To maintain safety in the event of
malfunction of the Relay, take appropriate safety
measures, such as installing a monitoring device on a
separate line.
If the wire insertion length is insufficient, fire may
occasionally occur, possibly resulting in physical
damage. Insert the wires all the way to the back.
The terminal block may be damaged if you insert a
flat-blade screwdriver in the release hole with
excessive force. Insert the flat-blade screwdriver into
the release holes with a force of 15 N or less.
CAUTION

situation which, if not avoided, may result
