1. Attach a ring lug to a 1.6 mm
2
(14 AWG) or larger wire.
2. Remove the grounding screw from the grounding terminal on the right side of
the chassis.
3. Attach the ring lug to the grounding terminal.
4. Tighten the grounding screw to 0.5 N · m (4.4 lb · in.) of torque.
5. Attach the other end of the wire to earth ground using a method appropriate
for the application.
Note
If you use shielded cabling to connect to a C Series I/O
module with a plastic connector, you must attach the cable shield
to the chassis grounding terminal using 1.3 mm
2
(16 AWG) or larger
wire. Use shorter wire for better EMC performance.
For more information about earth ground connections, go to
and enter
the Info Code earthground.
Connecting the Chassis to a Network
Connect the chassis to an Ethernet network using Ethernet port 1 on the front panel.
Use a standard Category 5 (CAT-5) or better shielded, twisted-pair Ethernet cable to
connect the chassis to an Ethernet hub or a computer.
Caution
To prevent data loss and to maintain the integrity of your
Ethernet installation, do not use a cable longer than 100 m.
The first time you power up the chassis, it attempts to initiate a DHCP network
connection. If the chassis is unable to initiate a DHCP connection, it connects to
the network with a link-local IP address with the form 169.254.x.x. After powerup,
you must install software on the chassis and configure the network settings in
Measurement & Automation Explorer (MAX).
