4.5 Electrical Connections
All of the electrical connections to the instrument are made at the termination area which
is located in the back of the analyzer under the access cover. Refer to Figure 6 carefully as
the wire colors do not follow the actual PCB screen printing. For easy access, loosen the
two clamping knobs and rotate the instrument upside down. Remove the access cover.

4.5.1 Power
Note: Only qualified electricians should be allowed to perform the installation of the
instrument as it involves a line voltage that could endanger life.
The power requirements for the analyzer are 40VA at 120 or 240 VAC. The voltage is set
at the factory based on the shipping destination; however the setting should be checked
prior to power connection.
To change the voltage, the fuse cartridge must be removed and rotated. The voltage is
indicated by the two arrows that point toward each other. A flat bladed screwdriver
inserted into the slot provided may be used to remove the fuse cartridge. See the Figure 11
in section 9.3.
4.5.2 Outputs -Voltage & Current
The analyzer can be set to output either voltage or 4-20 mA. This selection is made in the
DISPLAY PARAMETERS menu of the analyzer.
Use twisted pair shielded cable 22AWG-14 AWG for the voltage or current outputs. Tie
the shield at the recorder end only. Do not connect the shield at the analyzer.
The voltage connections are made at J6 as shown below:
