Wiring setups for hazardous area installations
There are five wiring options for hazardous area installations. In all cases, check the device
nameplate and process device tag to verify the approval rating.
1. Flameproof wiring
• For power demands see
Curve 2 (Flameproof, Increased Safety, Explosion-proof)
on
page 23.
• For wiring requirements follow local regulations.
• See also
Instructions specific to hazardous area installations
on page 13 and the ATEX
certificate listed above.
Note: ATEX certificates and connection drawings listed below can be downloaded from the

Notes:
• Depending on the system design, the power supply may be separate
from the PLC, or integral to it.
• Loop resistance (total of cable resistance plus 250 Ohm [resistor]) must
be less than 550 Ohm for the device to function properly.
