Publication 1752-UM001A-EN-P - October 2006
26 Installing and Wiring the SmartGuard 600 Controller
To comply with UL restrictions, DeviceNet connections and I/O must
be powered by dc sources whose secondary circuits are isolated from
the primary circuit by double insulation or reinforced insulation. The
dc power supply must satisfy the requirements for Class 2 circuits or
limited voltage/current circuits defined in UL 508.
The SmartGuard controller has three V/G terminal pairs that require a
power connection. There are two V0/G0 pairs, but because they are
internally connected, you only need to connect one V0/G0 pair. You
can use the other pair to distribute power to other devices.

You can configure the network and controller on the DeviceNet
network using a 1784-PCD card inside your personal computer and
RSNetWorx for DeviceNet software. You may also configure the
network and controller using the controller’s USB port and RSNetWorx
for DeviceNet software.
TIP
R
The following Rockwell Automation 1606 power supplies are
SELV- and PELV-compliant, and they meet the isolation and
output hold-off time requirements of the SmartGuard 600
controller:
• 1606-XLP30E
• 1606-XLP50E
• 1606-XLP50EZ
• 1606-XLP72E
• 1606-XLP95E
• 1606-XLDNET4
• 1606-XLSDNET4

WARNING
Do not connect or disconnect the communications cable with
power applied to this controller or any device on the network,
because an electrical arc can occur. This could cause an
explosion in hazardous location installations. Be sure that power
is removed or the area is nonhazardous before proceeding.
