Before You Begin
WARNING
Investigate and apply the most recent standards for Hazardous Locations for your area set by ANSI, ISO and OSHA, as well as all electrical codes
and fire and safety standards, to determine if your application will require a Hazardous Location model. If your application requires a Hazardous
Location model (ER5050), refer to Installing a Hazardous Location
Model (ER5050) on page 110 before following the steps listed in this section.
WARNING
Avoid personal injury or property damage from sudden release of pressure or bursting parts. Before proceeding with any
installation procedures:
• Always wear protective clothing, gloves and eyewear to prevent personal injury or property damage.
• Do not remove the ER5000 or any other component of the system while the system is pressurized.
• Disconnect any operating lines providing air pressure, electric power or a control signal to the ER5000 prior to installation
or maintenance.
• Use bypass valves or completely shut off the process to isolate the ER5000 and associated equipment from process pressure prior
to installation or maintenance. Relieve process pressure on both sides of the controller and associated equipment.
• Use lock-out procedures to be sure that the above measures stay in effect while you work on the equipment.
• Check with your process or safety engineer for any additional measures that must be taken to protect against process media dangers.
Do not install, operate or maintain an ER5000 controller or any associated equipment, without reading and fully understanding the
installation guidelines and operating instructions for every component of your application. To avoid personal injury or property
damage, it is important to carefully read, understand and follow all contents of this manual, including all safety cautions and
warnings in the Safety, Installation & Operations Precautions section. If you have any questions about these instructions, contact
your TESCOM™ sales ofce before proceeding.
