Wiring the Redundant Power Inputs
The first two pairs of contacts of the 10-contact terminal block
connector on the AWK-3251A-M12-RCC’s top panel are used for the
AWK-3251A-M12-RCC’s two DC inputs. The top view of the terminal
block connector is shown below.
STEP 1: Insert the negative/positive DC
wires into the
+/- terminals.
STEP
2: Insert the plastic terminal block
connector prongs into the terminal block
receptor, which is
located on the AWK-
3251A
-M12-RCC’s top panel.
NOTE
Before connecting the
AWK-3251A-M12-RCC’s
DC power inputs,
make
sure the DC power source voltage is stable.
•
The wiring for the input terminal block shall be installed by
a skilled person.
•
Wire type: Cu
•
Only use 16-22 AWG wire size.
•
Use only one conductor in a clamping point between the DC
power source and the power input.
ATTENTION
If the
AWK-3251A-M12-RCC is connected to a motor or other
similar type of equipment, be sure to use power isolation
protection. Before connecting the
AWK-3251A-M12-RCC to the
DC power inputs, make sure the DC power source voltage is
stable.
