Wiring setups for hazardous area installations

Note: ATEX certificates and connection drawings listed below can be downloaded from the
product page of our website at: www.siemens.com/LR200.
There are six wiring options for hazardous area installations. In all cases, check the device
nameplate and process device tag to verify the approval rating.

Notes:
• Depending on the system design,
the power supply may be separate
from the PLC, or integral to it.
• HART resistance (cable resistance
plus 250 Ohm [resistor]) must be
limited according to the allowable
operating area
• Do not connect more than one
HART programming device at a
time.
