Chapter 2: Installation
This chapter describes how to install the CLS200 series controller and its peripherals. Installation of
the controller involves the following procedures:
• Determining the best location for the controller
• Mounting the controller and TB50
• Power connection
• Input wiring
• Communications wiring (EIA/TIA-232 or EIA/TIA-485)
• Output wiring
WARNING! Risk of electric shock. Shut off power to your entire process before you
begin installation of the controller.
WARNING! The controller may fail in a 0% or 100% power output state. To prevent
death, personal injury, equipment damage or property damage, install external safety
shutdown devices. If failure may cause death or injury, you must install approved safety
shutdown devices that operate independently from the process control equipment.
Typical Installation
Figure 2.1 shows typical installations of the controller with the TB50 and the TB18 terminal blocks.
The type of terminal block you use greatly impacts the layout and wiring of your installation site. (See
Figures 2.2 to 2.11.)
We recommend that you read this entire chapter first before beginning the installation procedure.
This will help you to carefully plan and assess the installation.
