as well as the Hewlett-Packard oce. Keep the shipping
materials for the carrier's inspection.
To avoid damage to the instrument make sure that the
voltage selection switch on the back of the instrument is
set properly.
This is a Safety Class I product (that is, it is provided
with a protective earth terminal). An uninterruptible safety
earth ground must be provided from the main power
source to the product input wiring terminals through the
power cable or supplied power cable set. Whenever it is
likely that the protection has been impaired, the product
must be made inoperative and be secured against any
unintended operation.
If this instrument is to be energized via an external
autotransformer, make sure the autotransformer's
common terminal is connected to neutral (that is, the
grounded side of the line (Mains) supply.)
Before plugging the Fader into the line (Mains) voltage,
ensure the following steps are taken:
1. Check the line (Mains) voltage to ensure
compatibility with the Fader requirements.
2. Check the line voltage switch on the Fader's rear
panel to ensure proper selection for the line (Mains)
voltage.
