General Wiring

This section explains how to test your installation before you connect
power to it and how to connect inputs and outputs to it.

Power Wiring and System Test

When you have installed the system and the TB-50, use this checklist to
connect them. (These instructions are written so that non-electricians
can understand them. If you are an experienced electrician, they may
seem elementary to you. If so, feel free to skim them.)

Connecting Power and TB-50 to CAS

1.

Remove the temporary covers on the CAS housing.

2.

Connect the power supply. Do not turn on the AC power yet.

3.

Connect the ribbon cable to the system, as shown here. Plug it in so
the red stripe is on the left side as you face the back of the system.

4.

Connect the ribbon cable to the TB-50. The cable is keyed, so you
cannot insert it backwards.
