3. Secure the AC power wires to the marked terminals (L1 and L2N) on
the terminal block.
4. Secure the protective earth ground wire to the marked terminal on the
terminal block.
The protective earth terminal must be connected to a low-impedance
earth ground.
5. Apply power to the operator terminal.
Connect to a Network
The two Ethernet ports connect to controllers on an EtherNet/IP network by
using standard Ethernet connections. These network types are supported:
• Device Level Ring Network Topology
on page 48
• Linear Network Topology
on page 49
• Star Network Topology on page 50
Each of these EtherNet/IP network topologies supports applications that use
Integrated Motion over an EtherNet/IP network, if necessary.
Ethernet Ports
The Ethernet port has two 10/100Base-T connectors for network
communication and supports MDI/MDI-X connections and DLR network
topology as indicated by the DLR network icon.
ATTENTION: The earth ground connection to ground is mandatory.
This connection is required for noise immunity, reliability, and
Electromagnetic Compliance (EMC) with the European Union (EU)
EMC Directive for CE marking conformance. This connection is
required for safety by Underwriters Laboratory.
