Wiring Instructions
1. Locate terminal block at TC1 on the CM085 board. (See Figure 1-1 in this manual.)
TC1 should have 4 terminal locations (1, 2, 3 and 4) on it.
2. A twisted shielded wire should be used for connection to TC1. The shielded wire should
be separated and connected per the drawing below to eliminate interference due to
noise.

4. It is important that an appropriate wire size is selected. When the wire gauge is too thick,
it may apply pressure to the CM085 board and cause failure. When the wire gauge is too
thin, it may lead to imperfect contact or a break in the wire. The table below indicates
the suggested wire size to be used at TC1.

5. When stripping the wire end to be connected at TC1, approximately 5.5 mm of wire
should be exposed to make a good connection.
Note: Avoid sources of electric interference capable of inducing noise into the cable.
Communication and signal wiring should be kept separate from power wiring. If communication
or signal wiring must cross power wiring, it must cross at a right angle.
