Universal Inlet Power Supply
B.2.1
High Range Universal Supply with Terminal Power Strip, SWC
This standard power inlet module uses a three-position, screw-type terminal block, and includes surge
withstand capability (SWC). The terminal block is intended for use in installations where it is necessary or
desirable to have the instrument power hard-wired. See Figure B.1.

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 6 mm (1/4 in) 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 B.1).
