1. Intrinsically Safe wiring method (barrier required)
• For power demands see
Loop Voltage versus Loop Resistance
on page 21.
• For wiring requirements:
Europe/International: Follow local regulations.
US/Canada: Download
FM/CSA Intrinsically Safe connection drawing
(23650653)
from the product page of our website at:

or see Appendix A: page A-1.
• Use appropriate conduit seals to maintain IP or NEMA rating.
• Recommended Intrinsically Safe barriers are listed under
Passive Shunt Diode Barriers
on page 8 and
Active barriers (repeating barriers)
on page 9.
• Refer to
Instructions specific to hazardous area installations
on page 10.

Note: Selecting a suitable PLC input module, power supply, or barrier requires knowledge
about Intrinsic Safety and the application. It is the responsibility of the installer to ensure that
the intrinsically safe installation complies with both the apparatus approval requirements
and the relevant national code of practice.
Note: A well regulated supply voltage is required.
