3.2.1.1 IEC Line Input (AC Power) Connector
The IEC line input connector 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). These are provided within the body of
the connector, behind a small plastic flap.
A standard, detachable, non-locking, 3-prong power cord (IEC plug) supplies the Alternating
Current (AC) power to the UT-4500-A.
Observe the following:
AC Power Specifications
Input Power 75W maximum, less than 65W typical
Input Voltage 90-260VAC
Connector Type IEC-320
Fuse Protection Use T2.0A (slow-blow) 20mm fuses.

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