3.1 Safety notes for mounting and removal
Only qualified personnel must pack and unpack the RFC 4072S while observing the fol-
lowing ESD regulations.
WARNING: Loss of electrical safety and the safety function when using unsuitable
power supplies
The RFC 4072S is designed exclusively for protective extra-low voltage (PELV) operation
in accordance with EN 60204-1. Only PELV in accordance with the listed standard may
be used for the supply.
The following applies to the PROFINET network and the I/O devices used in it:
Only use power supplies that meet EN 61204 and feature safe isolation and PELV accord-
ing to EN 50178/VDE 0160 (PELV). These prevent short circuits between primary and
secondary sides.
Please also observe the information in Section “Electrical safety” on page 15 .
NOTE: Electrostatic discharge!
The device contains components that can be damaged or destroyed by electrostatic dis-
charge. When handling the device, observe the necessary safety precautions against
electrostatic discharge (ESD) according to EN 61340-5-1 and IEC 61340-5-1.
WARNING: Unintentional machine startup
Do not mount or remove the RFC 4072S while the power is connected.
Make sure the entire system is reassembled before switching the power back on. Observe
the diagnostic indicators and any diagnostic messages.
The system may only be started provided neither the device nor the system poses a haz-
ard.
Observe the PROFINET Installation Guideline for Cabling and Assembly
Observe the PROFINET Installation Guideline for Cabling and Assembly when mounting
and installing the RFC 4072S.
Observe the corresponding information in the Installation Guideline for Cabling and
Assembly and in the “Functional Earthing and Shielding of PROFIBUS and PROFINET”
document for the grounding concept in particular.
Both documents can be downloaded at www.profinet.com or you can contact your near-
est Phoenix Contact representative regarding the two documents.
