• For power demands see
• For wiring requirements:
Europe/International: Follow local regulations.
US/Canada:
• Use appropriate conduit seals to maintain IP or NEMA rating.
• Recommended Intrinsically Safe barriers are listed under
Active barriers (repeating barriers)
on page 8 and
Instructions specific to hazardous area installations
• Refer to
: Selecting a suitable PLC input module, power supply, or barrier requires knowledge
Note
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.
Passive Shunt Diode Barriers
: A well regulated supply voltage is required.
