Figure 6 shows the electrical connectors and fittings on the instrument. To keep the environmental
rating of the enclosure, make sure that there is a plug in the strain relief fittings that are not used and
a connector cap on the unused connectors.
Based on the controller configuration, the controller has:
• Ethernet connectors (LAN) to give internet access to the controller through a customer network.
• Ethernet connectors for Industrial Ethernet Protocols: EtherNet/IP or PROFINET.
• Digital SC connectors for sc digital sensors, sc digital gateways and analyzers.
A color code identifies the connectors. The LAN connectors are green. The EtherNet/IP or
PROFINET connectors are yellow. The sc digital sensor connectors are black. Refer to Table 1 for
the applicable options for each connector and fitting.
Note: The controller is supplied without strain relief fittings installed. The user must supply the necessary strain
reliefs. Refer to Replacement parts and accessories on page 47.
