Model TA502A
Figure 11: Control Module Coding Strip
Zero Two series modules require air circulation to avoid excessive heat build-up. If
chassis are stacked vertically within an enclosure, forced air circulation may be required.
The Trip Amplifier Modules are largely immune to electromagnetic interference (EMI).
However, they should not be mounted in close proximity to radio transmitters or similar
equipment.
2.3 Rear Terminal Connections
All wire connections to the Model TA502A are made to the terminal block located at the
rear of the chassis. The terminal block accepts 16-AWG to 20-AWG, stranded or solid-
core wire. 14-AWG wire may be used if it is properly stripped as shown in Figure 12.

WARNING:
Contact with PC Board components should be avoided in order to prevent
damage by static electricity.
NOTE:
To connect wires to the terminal block on the Model TA502A, loosen the desired
screw, insert the stripped end of the wire and tighten.
