Power Supply

12 - 48 VDC

The TCC-120/120I is powered

by an external 12-48 VDC

power supply. To connect to the

power supply, run two wires

from the V+ and V- terminals,

on the TCC-120’s 3-connector

terminal block, to the DC power

supply, as shown in the figure

on the left.

Once the power supply is

connected to its power source,

the PWR LED located on the

TCC-120’s top panel should be

illuminated in red.
