Safety
This Section includes general safety instructions for handling the RSTi-EP system. Specific
safety instructions for specific tasks and situations are given at the appropriate places in the
documentation.
When using remote I/O RSTi-EP modules, refer to the Module for Functional Safety Manual
(GFK-2956).
2.1
General Safety Notice
Work on the RSTi-EP products may only be performed by qualified personnel with the
support of trained persons. As a result of their professional training and experience, such
personnel are qualified to perform the necessary work and identify any potential risks.
Before any work is carried out on the products (installation, maintenance, retrofitting), the
power supply must be switched off and secured against being switched on again. Work may
be carried out with safety extra-low voltage.
The manual provided with the equipment shall be followed in detail to assure proper and
safe operation.
A stabilized 24Vdc power supply shall be used.
All field wiring intended for connection to the power terminal shall consist of copper
conductors with the insulation locally removed. Additional intermediate connecting parts,
other than ferrules, shall not be used.
When working during continued operations, the emergency stop mechanisms must not be
made ineffective. If you need technical help, contact Technical Support. For phone numbers
and email addresses, refer to the General Contact Information page in the front of this
manual.
If a malfunction on a RSTi-EP product cannot be fixed after following the recommended
measures (refer to Section 12, LED Indicators and Troubleshooting), the product in question
must be sent back to Emerson.
Emerson does not assume any liability if the base or electronic module has been tampered
with.
2.1.1
Electrostatic Discharge
RSTi-EP products can be damaged or destroyed by electrostatic discharge. When handling
the products, the necessary safety measures against electrostatic discharge (ESD)
according to IEC 61340-5-1 and IEC 61340-5-2 must be observed.
All devices are supplied in ESD-protected packaging. The packing and unpacking as well as
the installation and disassembly of a device may only be carried out by qualified personnel
and in accordance with the ESD information.
