Attaching the DC Power Connectors
Warning:
This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that the
protective device is rated not greater than: 5A. Statement 1005
To attach the power connectors:
Step 1
Insert the power connector into the receptacle on the IC3000 front panel.
Step 2
Use a ratcheting torque flathead screwdriver to tighten the captive screws on both sides of the power connector to
5 in-lb (0.6 N-m).
When you are testing the device, one power source is sufficient. If you are installing the device and are using a
second power source, repeat this procedure for the second power connector (DC-B), which installs just below the
primary power connector (DC-A).
When you are installing the device, secure the wires coming from the power connector so that they cannot be
disturbed by casual contact. For example, use tie wraps to secure the wires to the rack.
Warning:
Failure to securely tighten the captive screws can result in an electrical arc if the connector is accidentally
removed. Statement 397
Warning:
When you connect or disconnect the power and/or alarm connector with power applied, an electrical arc
can occur. This could cause an explosion in hazardous area installations. Be sure that all power is removed from the
device and any other circuits. Be sure that power cannot be accidentally turned on or verify that the area is
nonhazardous before proceeding. Statement 1058
Connecting to the IC3000 Ports
For hazardous location environments, follow these warnings when connecting to the destination ports (Gigabit Ethernet
and console ports).
Warning:
Do not connect or disconnect cables to the ports while power is applied to the device 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 from the device and cannot be accidentally be turned on, or verify that the area is
nonhazardous before proceeding. Statement 1070
Warning:
If you connect or disconnect the console cable with power applied to the device or any device on the
network, 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. Statement 1080
Connecting to the USB Ports
Note: If you are connecting to the USB ports:
A connection (to the USB ports) can only be made in a non-hazardous environment
The USB port covers must be reinstalled before the IC3000 can be deployed in a hazardous environment
For more information about connecting to the USB port, see the
