Warning! Power down and disconnect the power cord before servicing or wiring the serial
device server.
Caution! Do not disconnect modules or cabling unless the power is first switched off.
The device only supports the voltage outlined in the type plate. Do not use any other power
components except those specifically designated for the serial device server.
Caution! Disconnect the power cord before installation or cable wiring.
The STM-60XC series supports dual 12 to 48 VDC power inputs and power-fail relay output.
