The details of installing and wiring the controller and external input/output
devices are beyond the scope of this guide.
If you are using a field–wired fixed or modular controller, refer to the
Installation and Operation Manuals, Publication 1747–800 (fixed controllers)
and 1747–804 (modular controllers), for information on installation and
wiring of the controller and external input/output devices.
We recommend that your controller have two external input circuits and two
external output circuits to complete the exercises in this guide.
The HHT (with communication cable), the memory pak, and the battery are
supplied separately. Install the memory pak, battery, and communication
cable as follows:
1. Install the memory pak first. The English version is catalog number
1747–PTA1E.
Important: The memory pak contains CMOS devices. Wear a
grounding strap and use proper grounding procedures to
guard against damage to the memory pak from
electrostatic discharge.
A. To install the memory pak, remove the cover from the back of the
HHT.
