Wiring the ET 200iSP
5.4.1
Wiring Rules for the ET 200iSP
DANGER
When laying cables and wiring, make sure that you adhere to the installation regulations
complying with EN 60 079-14 and any regulations specific to your country.
When operating the ET 200iSP in areas with combustible dust (Zone 21, Zone 22), you must
also comply with EN 61241-14.
DANGER
Connecting an intrinsically safe sensor, actuator, or HART field device to the input/output of
an electronic module must produce an intrinsically safe circuit! For this reason:
When you select the encoder, actuator or HART field device to be connected to the electronic
module, the resulting safety-related values must be checked!
The inductance and capacitance of the cable must also be taken into account! Refer to
Configuration Options in Zones (Page 48).
WARNING
If the wrong electronic module is used or the terminals are connected incorrectly to the
sensors, actuators or HART field devices, the intrinsic safety is put at risk:
Connect only Ex i circuits to the intrinsically safe inputs and outputs of the electronic modules.
Check the wiring between the electronic modules and sensors, actuators, and HART field
devices.
