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.
