Precautions
1. Do not use or store the Temperature Monitoring Relay in the
2. Use and store the Temperature Monitoring Relay within the rated
3. Mount the Temperature Monitoring Relay in the correct direction.
Do not touch the terminals while power is being supplied.
Doing so may occasionally result in minor injury due to
electric shock.
Do not allow pieces of metal, wire clippings, or fine
metallic shavings or filings from installation to enter the
product. Doing so may occasionally result in electric
shock, fire, or malfunction.
Do not use the product where subject to flammable or
explosive gas. Otherwise, minor injury from explosion
may occasionally occur.
Never disassemble, modify, or repair the product or touch
any of the internal parts. Minor electric shock, fire, or
malfunction may occasionally occur.
Loose screws may occasionally result in fire.
Tighten terminal screws to the specified torque of 0.54 to
0.55 N·m.
Set the parameters for the Temperature Monitoring Relay
so that they are appropriate for the system being
monitored. If they are not appropriate, unexpected
operation may occasionally result in equipment damage
or accidents.
Use the following procedure to make the Temperature
Monitoring Relay settings.
• Make settings for the Temperature Monitoring Relay so
• Turn the power supply to the Temperature Monitoring
A malfunction in the Temperature Monitoring Relay may
occasionally make monitoring operations impossible and
prevent alarm outputs, resulting in property damage to
facilities and devices. Conduct periodic maintenance of
the Temperature Monitoring Relay. To maintain safety in
the event of malfunction of the Temperature Monitoring
Relay, take appropriate safety measures, such as
installing a monitoring device on a separate line.
If the output relay is used past its life expectancy, contact
fusing or burning may occasionally occur. Always
consider the application conditions and use the output
relay within its rated load and electrical life expectancy.
The life expectancy of output relays varies considerably
with switching capacity and switching conditions.
that they are appropriate for the system being
monitored.
Relay OFF before setting the switches provided on the
side of the Temperature Monitoring Relay. The settings
made on the switches on the side of the Temperature
Monitoring Relay will be enabled when the power
supply is turned ON.
