cables for DATA I/O. These cables must be double-shielded from end-to-end, ensuring a
continuous ground shield.

IEC 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.
