CE-EMC Protection Installation Procedure
Wiring
Thermo Fisher Scientific LevelPRO Installation Guide
E-7
The connections shown in Figure E–8 are listed below:

The connections on the J4 connector are to be wired to the
detector .

The connections on the
J3
connector are to be wired to the
customer’s system
.

J1 is for incoming 24 Vdc power .

J2
is for the
filtered 24 Vdc power to go to the detector
(if the
detector is DC powered).

J5 must be connected to Earth Ground .
Warning
Do not exceed the voltage limitations of the individual
connections or damage will occur to the EMC protection board.

Note
There must be less than 1 ohm resistance from the J5 terminal to
true earth ground.

The J2 connector has been wired at the factory with two 18 gauge wires,
which should only be used only for a 24 Vdc output if the detector is DC
powered. The RED wire is for positive side of the 24 Vdc input and the
BLACK wire is for the negative side of the 24 Vdc output.
The J4 connector has been wired at the factory with twelve 22 gauge wires,
which should be used only for signal wiring such as RS232, RS485, 4–20
mA current output, and 9723 local display. Connections 1 through 4 are
limited to 9 Vdc, connections 5 through 8 are limited to 20 Vdc, and
connections 9 through 12 are limited to 36 Vdc.
The wiring color code for the factory installed signal cable is as follows:
