12. Connect power, analog output and RS485 if desired. Run the power in one conduit, and the
analog output and RS485 in another. You can use flexible conduit for Class 1 Div. 2 areas. See the
NEC.
All the electrical connections are located on a single Phoenix pluggable connector behind a panel on the left
side of the analyzer. Make sure the wires are connected per the markings – Positive to +ve, return to the
ground symbol. This terminal should also be used if required for any shield connections for the output or
RS485 connections. The output connections are made on positions 3 and 4, and the RS485 connections on
5 and 6.
The analog output – which may be either 1-5V or 4-20mA – is connected to the “+” and “-“ symbols (3 and
4). This signal is isolated from ground. If the device to which you are connecting is also isolated from
ground, make sure you ground the “-“ connection at the analyzer. The terminal marked by the ground
symbol may be used for this purpose, in which case the output is no longer isolated. DO NOT GROUND
