Option 10: Inlet Power Supply Description
C.9.1
110 to 350 Vdc, 85 to 250 Vac, 47 to 440 Hz Terminal Power Strip, SWC
Option 10 replaces the standard IEC-320 power input module with a three-position, screw-type
terminal block, including Surge Withstand Capability (SWC). This feature is intended for use
in installations where it is necessary or desirable to have the instrument power hard-wired. See
Figure 3.3.

Surge Withstand Protection (SWC)
Provides input Surge Withstand Capability (SWC) in compliance with both ANSI C37.90 and IEC
801-4.
Connections
All input power line connections to the rear-panel terminal strip should be made using appropriate
power cables which have the insulation removed about 1/4” from the end or as required for tinning.
If a DC source is used, connect the positive lead to the positive (+) terminal, connect the negative
lead to the negative (
−
) terminal and a safety ground lead to the “G” terminal when viewing the
instrument from the rear (see Figure 3.3).
