must be followed before the instrument is switched on:
(a) While this is a Class I product, provided with a protective
earthing conductor in a power cord, an external protective earthing
terminal has also been provided. This terminal is for use where the
earthing cannot be assured. At least an 18AWG earthing conductor
should be used in such an instance, to ground the instrument to an
assured earth terminal. The external protective earth terminal is on
the rear of the instrument as shown on page 35.
(b) If this instrument is to be energized via an auto-transformer to
reduce or increase the line voltage, make sure that the common
terminal is connected to the neutral pole of the power source.
(c) The power cable plug shall only be inserted into a socket outlet
provided with a protective ground contact. The protective action
must not be negated by the use of an extension cord without a
protective conductor (grounding).
