Chapter 2:
Installation
This chapter describes how to install the D8 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
• 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 percent or 100 percent power output state.
To prevent death, personal injury, equipment damage or property damage, install
external safety shutdown devices that operate independently from the process control
equipment.

Typical Installation

Figure 2.1 on the following page 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 Figure 2.2 to Figure 2.10 to determine potential space requirements.
We recommend that you read this entire chapter before beginning the installation procedure. This will
help you to carefully plan and assess the installation.
