Power Supply
• Bus voltage: 21 to 30 Vdc (Class 2) provided through the bus line
• Operating voltage:
This product can receive power from only one of the following:
− 29 Vdc from the Power Supply N 125/21 (If the N 125/21 is in the same
cabinet, this is the preferred solution. If not, one of the following alternates
may be used.)
