Chapter 1
Safety
This chapter deals with your own safety and the safety of the equipment
operators.
Read this chapter carefully before working with the 842E EtherNet/IP encoder
or the machine or system in which the 842E EtherNet/IP encoder is used.
Authorized Personnel
The following qualifications are necessary for the various tasks:
Correct Use The 842E EtherNet/IP Absolute Encoder is an instrument that is
manufactured in accordance with recognized industrial regulations. It also
meets the quality requirements as per ISO 9001:2008 and of an environment
management system as per ISO 14_001:2009.
An encoder is a device for mounting that cannot be used independently of its
foreseen function. For this reason, an encoder is not equipped with immediate
safety devices. As per statutory regulations, the operator of the system provides
considerations for the safety of personnel and systems. Due to its design, the
842E EtherNet/IP can only be operated within an EtherNet/IP network. It is
ATTENTION: Only authorized personnel can install, commission, and service
the 842E EtherNet/IP encoder.
Only trained and authorized Rockwell Automation® service personnel can make
repairs to the 842E EtherNet/IP encoder.

necessary to comply with the EtherNet/IP specifications and guidelines for
installing an EtherNet/IP network. If any modifications are made to the 842E
EtherNet/IP encoder, any warranty claim against Rockwell Automation is
rendered void.
General Safety Notes and
Protective Measures
Environmental Protection Note the following information on disposal.
ATTENTION: Observe the following procedures to confirm the correct and
proper use of the 842E EtherNet/IP encoder.
Qualified personnel with knowledge of electronics, precision mechanics, and
control system programming install and maintain the encoder. It is necessary to
comply with the related standards for the technical safety stipulations.
All persons who install, operate, or maintain the device have to meet the safety
regulations:
• The operating instructions must always be available and must always be
followed.
• Unqualified personnel are not allowed to be present in the vicinity of the
system during installation.
• The system is to be installed in accordance with all applicable safety
regulations and the mounting instructions.
• All work safety regulations of the applicable countries are to be followed
during installation.
• Failure to follow all applicable health and safety regulations results in
personal injury or damage to the system.
• The current and voltage sources in the encoder are designed in accordance
