POWER INPUT Connector Block
The method of connection is as follows:
a. Turn off the power. Ensure that both ends of the power cable are potential
free i.e., not connected to a power supply.
b. Remove the terminal block from the
POWER INPUT
socket.
c. Strip back the wires of the power cable, exposing approximately 6mm
(0.2”) - the use of crimps/wire ferrules is recommended.
d. Insert the +24 V DC lead into the
24V
terminal way on the terminal block
and tighten the screw.
e. Insert the 0V lead into the
0V
terminal way on the terminal block and
tighten the screw.
f.
Check that the wiring has been completed correctly.
g. Push the terminal block firmly back into the
POWER INPUT
socket.
NOTE: There is no power switch for the DC power supply version;
the analyzer will be turned on automatically as soon as power is
supplied.
Connect the free end of the power cable to a suitable DC power
supply source (voltage range 10...72 V DC). The instrument may then be
switched on, as required, by the power switch at the source.
