Installing and Wiring the SmartGuard 600 Controller Chapter 2
Connecting to USB Port
Connect the USB communication connector to your personal computer when
you want to configure the network and controller by using RSNetWorx for
DeviceNet software. Use a commercially available USB-A to USB-B male/male
cable to make the connection.
Connecting to the Ethernet port
Depending on where you plan to route your cable you must select the correct
cable for the environment. Shielded cable performs better than non shielded
cable in industrial environments. In particular, if your application is in a high
noise environment or your cable must be run in close proximity to noise radiating
sources then you should plan to use shielded cables.
You should consider shielded cables if your application includes one or more of
the following:
• spot welding control
• Motor Control Centers
• drives greater than 10 Hp
• induction welding processes
• proximity to high-power RF radiation
• electrostatic processes
• high current devices (greater than 100 A)
Use an RJ45 connector to connect the controller to the EtherNet/IP network.
When connecting to the SmartGuard controller to a switch or a hub, use a
ATTENTION: To reduce the potential for electromagnetic interference, the USB
cable length must be less than 3 m (10 ft).
The USB port is intended for temporary programming purposes only and is not
intended for permanent connection.
ATTENTION: If you connect or disconnect the USB cable with power applied to
this module or any device on the USB network, an electrical arc could occur. This
could cause an explosion in hazardous location installations. Be sure that power
is removed or the area is nonhazardous before proceeding.
IMPORTANT
Shields play an important role in providing noise immunity for your system.
However, an improperly installed shielded cable can cause problems due to
voltage offsets in your grounding system. To help minimize the effects of
ground offsets you will need to isolate the shield at one end of the cable. In this
case the shield should be isolated at the deice, not at the switch.
