3.4 Connecting
All connections to the Gateway can be made at the terminal block, which is located in the lower
junction box section of the enclosure. The terminal block label is located on the inside of the
lower cover. See Figure 3-6 for the standard terminal block label.
The junction box portion of the enclosure has four conduit entries for power and
communications wiring. Do not run communication wiring in conduit or open trays with power
wiring, or near heavy electrical equipment.
Install the included conduit plugs in any unused conduit openings. For NEMA
®
4X and IP65
requirements, use thread seal (PTFE) tape or paste on male threads to provide a watertight seal.
3.4.1 Grounding
The Gateway enclosure case should always be grounded in accordance with national and local
electrical codes. The most effective grounding method is a direct connection to earth ground
with minimal impedance. Ground the Gateway by connecting the external grounding lug to
earth ground. The connection should be 1 Ω or less. The external ground lug is located below
the Gateway enclosure and is identified by the following symbol:
3.4.2 Ethernet
The Gateway is equipped with two 10/100BaseTX Ethernet communications ports (see
Figure 3-6). These connections can be used to access the Gateway’s web interface and to
communicate Modbus TCP and OPC protocols.
The primary Ethernet port (Ethernet 1) is used to connect to the host system or other
application systems. The secondary Ethernet port (Ethernet 2) can be used as a back up
connection or a maintenance port for local access to the Gateway.
