Note: The European EMC Directive (EN55022, EN50082-1) requires using properly shielded cables for DATA I/O. These cables must be double-shielded from end-to-end, ensuring a continuous ground shield.

4.3.1IEC Line Input 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 contained within the body of the connector, behind a small plastic flap.

•For 230 volt AC operation, use T0.75A, (slow-blow) 20mm fuses.

•For 115 volt AC operation, use T1.25A, (slow-blow) 20mm fuses.

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