Safety Precautions
■ Precautions for Safe Use
Observe the following points to ensure safe operation.
1. The product is designed for indoor use only. Do not use the
2. Use and store the product within the rated temperature and
3. To allow heat to escape, do not block the area around the product.
4. Be sure to wire properly with correct polarity of terminals.
5. Use specified size (M3, width 5.8 mm or less) crimped terminals
6. Do not wire terminals that do not have an identified use.
Do not touch the terminals while power is being supplied.
Doing so may occasionally result in minor injury due to
electric shock.
Use a power supply that complies with the reinforced
insulation specified in IEC 60664 for the EJ1 external
power supply or the power supply connected to the EJ1.
If non-compliant power supplies are used, electric shock
may occasionally result in minor injury.
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.
Tighten the terminal screws to between 0.40 and
0.56 N·m. Loose screws may occasionally result in fire.
Set the parameters of the product so that they are
suitable for the system being controlled. If they are not
suitable, unexpected operation may occasionally result in
property damage or accidents.
A malfunction in the product may occasionally make
control operations impossible or prevent alarm outputs,
resulting in property damage. To maintain safety in the
event of malfunction of the product, take appropriate
safety measures, such as installing a monitoring device
on a separate line.

• Places subject to intense temperature change
• Places subject to icing or condensation
• Places subject to vibration or strong shocks
humidity ranges. Provide forced-cooling if required.
Do not block the ventilation holes on the product.
for wiring. To connect bare wires to the terminal block, use copper
braided or solid wires with a gage of AWG22 to AWG14 (equal to
cross-sectional area of 0.326 to 2.081 mm
