3.4.4 Sensor Wiring to Signal Boards
Wire the correct sensor leads to the measurement board using the lead locations marked directly on the board.
After wiring the sensor leads to the signal board, carefully slide the wired board fully into the enclosure slot and
take up the excess sensor cable through the cable gland.
For best EMI/RFI protection use shielded output signal cable enclosed in an earth-grounded metal conduit.
Connect the shield to earth ground. AC wiring should be 14 gauge or greater. Provide a switch or breaker to dis-
connect the analyzer from the main power supply. Install the switch or breaker near the analyzer and label it as
the disconnecting device for the analyzer.
Keep sensor and output signal wiring separate from power wiring. Do not run sensor and power wiring in the same
conduit or close together in a cable tray.
3.4.3 Alarm Relay Wiring
Four alarm relays are supplied with the switching power supply (85 to 265VAC, -03 order code) and the 24VDC
power supply (20-30 VDC, -02 order code). Wire the relay leads on each of the independent relays to the correct
position on the power supply board using the printed lead markings (NO/Normally Open, NC/Normally Closed, or
Com/Common) on the board. See Fig 3-4.
3.4.2 Current Output Wiring
All instruments are shipped with two 4-20 mA current
outputs. Wiring locations for the outputs are on the
Main board which is mounted on the hinged door of the
instrument. Wire the output leads to the correct posi-
tion on the Main board using the lead markings (+/positive,
-/negative) on the board. Male mating connectors are
provided with each unit.
