Precautions for Safe Use
1. Do not use or store the product in the following locations.
• Locations subject to water, or oil
• Outdoor locations or under direct sunlight
• Locations subject to dust or corrosive gases (sulfurizing gases,
ammonia gases, etc.)
• Locations subject to rapid temperature changes
• Locations prone to icing and dew condensation
• Locations subject to vibration and large shocks
• Locations subject to wind and rain
• Locations subject to static electricity or noise
• Locations subject to insects or small animals
2. Use and store the product in a location where the ambient
temperature and humidity are within the specified ranges. If
applicable, provide forced cooling.
3. Check terminal polarity when wiring and wire all connections
correctly.
4. Do not wire the input and output terminals incorrectly.
5. Make sure the power supply voltage and loads are within the
specifications and ratings for the product.
6. Make sure the ferrule terminals for wiring are of the specified size.
7. The stripping length is 8 mm. Insert the wires all the way to the
back.
8. Do not connect anything to terminals that are not being used.
9. Use a power supply that will reach the rated voltage within 1
second after the power is turned ON.
10.Keep wiring separate from high voltages and power lines that draw
large currents. Do not place product wiring in parallel with or in the
same path as high-voltage or high-current lines.
11.Do not install the product near equipment that generates high
frequencies or surges.
12.The product may cause incoming radio wave interference. Do not
use the product near radio wave receivers.
13.Install an external switch or circuit breaker and label it clearly so
that the operator can quickly turn OFF the power supply.
14.Make sure the indicators operate correctly. Depending on the
application environment, the indicators may deteriorate
prematurely and become difficult to see.
15.Do not use the product if it is accidentally dropped. The internal
components may be damaged.
16.Be sure you understand the contents of this catalog and handle
the product according to the instructions provided.
17.Do not install the product in any way that would place a load on it.
18.When discarding the product, properly dispose of it as industrial
waste.
19.The product must be handled only by trained electrician.
20.Prior to operation, check the wiring before you supply power to the
product.
21.Do not install the product immediately next to heat sources.
22.Perform periodic maintenance.
23.Do not wire anything to the release holes.
24.When you insert a flat-blade screwdriver into a release hole, do not
tilt or twist the screwdriver. The terminal block may be damaged.
25.Insert a flat-blade screwdriver into the release holes at an angle.
The terminal block may be damaged if the screwdriver is inserted
straight in.
26.Do not allow the flat-blade screwdriver to fall when you are holding
it in a release hole.
27.Do not bend a wire past its natural bending radius or pull in it with
excessive force. Doing so may break the wires.
28.Do not insert more than one wire into each terminal insertion hole.

29.To prevent wire materials from smoking or igniting, use the wiring
materials given in the following table.
Recommended wire
2
0.25 to 1.5mm /Equivalent to AWG24 to 16
Note: Please use Ferrules with UL certification (R/C).
30.Use only the specified wires for wiring.
31.When wiring the terminals, allow some leeway in the wire length.
32.Make sure that the power supply is turned OFF before you change
any DIP switch setting.
Precautions for Correct Use
Observe the following operating methods to
prevent failure and malfunction.
1. Use the power supply voltage, input power, and other power
supplies and converters with suitable capacities and rated outputs.
2. The distortion in the input waveform must be 30% max. If the input
waveform is distorted beyond this level, it may cause unnecessary
operation.
3. The product cannot be used for thyristor control or on the
secondary side of an inverter. To use this product on the primary
side of an inverter, install a noise filter on the primary side of the
inverter.
4. Phase loss is detected only when the power supply to the motor is
turned ON. Phase loss during motor operation is not detected.
5. Phase loss can be detected only from the input contacts to the
power supply side. Phase loss cannot be detected from the input
contacts to the load side.
6. When cleaning the product, do not use thinners or solvents. Use
commercial alcohol.
7. If you use stranded wires, make sure that there are no loose wire
strands.
8. If you wire crossovers and connect terminal blocks in parallel, a
large current will flow. Make sure that the current does not exceed
10 A.
9. The terminal block may be damaged if the recommended tool is
not used. Use the recommended flat-blade screwdriver to operate
the release holes.
Correct Mounting Direction, Mounting, and
Removing
Mounting to DIN Track
To mount the Relay to a DIN Track, hook the Relay onto the DIN
Track and press the Relay in the direction of the arrow until you hear
it lock into place.
(1)
Removing from the DIN Track
To remove the Relay, insert a screwdriver into the hook on the top or
bottom and pull out the hook to release the Relay.
• Leave at least 30 mm of space between the product and other
devices to allow easy installation and removal.
