STEP 2: Attach the power supply
The TCC-100 is powered by an
external 12 to 48 VDC power supply.
To connect the power supply, run two
wires from the V+ and V
- terminals
on
the TCC’s 3-connector terminal
block to the DC power supply, as
shown in the figure. Once the power
supply is connected to its power
source, the PWR LED located on
the
TCC
’s top panel should turn red.
NOTE
The TCC
-100 series supports reverse power protection. That is
, it
will automatically detect which power wire is negative, and which
is positive.
STEP 3: Wire the terminal block
There are three wiring options available for connecting to the TCC-100’s
RS-422/485 terminal block.
