openings provided on the
left side of the front
cover.

B – Use the open space
provided inside the drive
to route option wiring.
Figure 7 Wire Routing Examples
<1> The drive will not meet NEMA Type 1 requirements if wiring is exposed outside the enclosure.
6.
Connect the Ethernet communication cable to the option modular connector (CN1)
port 1.
To connect the option to a network, firmly connect RJ45 8-pin shielded twisted pair
Cat5e cable(s) into the modular connector ports (see
Figure 7 ).
IGMP Snooping
Switches implementing IGMP Snooping are strongly recommended. When IGMP
Snooping is used, devices will only receive the multicast packets in which they are
interested.
Communication Cable Specifications
Only use cable recommended for EtherNet/Industrial Protocol (EtherNet/IP™). Using
a cable not specifically recommended may cause the option or drive to malfunction.
Refer to the ODVA website for more information on network cabling (http://
www.odva.org).
The dual RJ45 network ports on the option board act as a switch to allow for flexibility
in cabling topology. For example, a traditional star network topology may be employed
by using a single port on the option board. Alternatively, a daisy-chained approach
may be employed by using both RJ45 ports. The daisy-chained approach reduces
the requirements of central switch ports. A ring topology is also possible.
