3.2.1.1 AC Power IEC Line Input Connector Module
The 3-prong IEC line input connector module (IEC-60320 style C14)
contains the ON/OFF switch for the unit. It is also fitted with two fuses,
one each for line and neutral connections (or L1, L2 where
appropriate). The fuses are contained in a fuse holder that is press-fit
into the body of the connector.
A standard, detachable, non-locking, 3-socket power cord (IEC-60320 style C13 plug) supplies
the Alternating Current (AC) power to the UT-4500-A.
Note the following:
75W maximum, less than 65W typical
Use (2) T2.0A 20mm slow-blow fuses.

For continued operator safety, always replace the fuses with the correct type
and rating.
