IEC Power Connector
The UDM-0808-SIG uses a universal switch-mode power supply, which operates from 90-264V AC,
50/60Hz, with a power consumption of 130W fully loaded.
The rating label found to the bottom left of the Hub, beneath the IEC connector, contains important
information applicable to the Hub's installation environment.
The Power On/Off switch is located beside the IEC power connector.
Powering the UDM-0808-SIG Hub On
1.
Ensure a standard PC mains lead has been connected to the 3-pin power connection, and then connected
to a mains power source.
2.
Flip the power switch down to its On (|) position.
The Power Status light bar indicates that the Hub is receiving power.
While the Hub boots, the left-most front panel LED (FIG. 11) will blink until the Hub is fully booted and
connected to a NetLinx Master. If the Hub is not configured to properly connect to a master it will continue to
blink indefinitely until the configuration is changed.
Powering the UDM-0808-SIG Hub Off

Where a mains plug (or appliance coupler) is used in the event of a fault, the Hub can
be disconnected from the mains by removing the lead from the IEC inlet or from the
mains socket.
It is important that the Hub is installed in such a way that this method remains readily
operable.
The user should have easy access to either the IEC inlet or the mains socket in the
event of a fault.
