3.1.1
Connecting Inlet Power
To provide for a wide range of inlet power sources, the 1133A can be ordered with either of two
different power supplies: a low-range DC only and a high-range AC/DC supply. Each of the power
inlet module connectors are illustrated here and also in Chapter 2. Take time to examine the power
inlet module connection on your Model 1133A to verify that it is correct according to your order.
Make sure to check the inlet module before connecting power to the 1133A.

Option 03, 110 to 350 Vdc Terminal Power Strip, Surge Withstand
The power inlet connector for Option 03 is a 3-pole terminal strip and provides input surge
protection for compliance with ANSI C37.90-1 and IEC 801-4. Input voltages are: 85 Vac to
264 Vac, 47 Hz to 440 Hz, or 110 Vdc to 350 Vdc, less than 20 Watts typical.
