Chapter 2 Installation of this Device
• Withstand voltage test
This product does not satisfy the withstand voltage specifications required by the above
standard. The conditions of the withstand voltage test are as follows:
Applied between the supply terminal (+ and - terminals are connected) and the ground terminal
in the terminal box
Applied voltage: 500 V DC (specified in section 6.3.13 in Part 6 of the above standard)
Applied for: 1 minute
2-1-3 Equipment use conditions
(1) Use conditions for intrinsically safe explosion-proof models
• If installed and used in an area that requires EPL Ga equipment, make sure that ignition sparks
will never be emitted due to friction or a shock.
• If installed and used in an area that requires EPL Da equipment, electrostatic discharge must be
prevented by taking measures such as wearing antistatic shoes or wristbands, or laying antistatic
floor mats.
• This product does not satisfy the withstand voltage specifications required by Recommended
Practices for Explosion-Protected Electrical Installations in General Industries (2008 technical
recommendations conforming to international standards). Accordingly, use of insulation
barriers is recommended. If zener barriers are used, connect the transmitter and zener barriers
to the same equipotential bonding system.
