1 SAFETY PRECAUTIONS
The
equipment described in this manual has been
designed
in accordance with
IEC publication 1010
Safety
Requirements for Electronic Measuring Apparatus,
and has
been supplied in a safe condition. To
avoid injury
to
an operator
or
service technician the safety precautions given below, and throughout the manual,
must
be
strictly adhered to, whenever the
equipment
is
operated, serviced
or
repaired.
The equipment is designed solely for electronic measurement and should be used
for no other purpose. Solartron
accept
no responsibility for accidents or
damage
resulting from any failure to comply with these precautions.
1.1
GROUNDING
To minimize the hazard of electrical shock it is essential that the equipment
is
connected to a protective ground whenever the power supply, measurement or
control circuits
are
connected,
even
if the equipment is switched off.
A PROTECTIVE GROUND is connected via the a.c. supply cord. The cord
must
be plugged into an ac line outlet
with
a
protective ground
contact. When an
extension lead is used, this must also contain a ground conductor. Always connect
the
a.c. supply cord to the
supply
outlet before
connecting the control
and signal
cables; and, conversely, always disconnect control and signal cables before
disconnecting the
ac supply cord. The a.c.
ground connection
must
have
a
continuous current rating
of 25A.
A high quality SIGNAL GROUND, for measurement purposes, is
provided
in the
form of a binding post.
This is
linked internally to PROTECTIVE GROUND.
Where both protective
and signal
grounds are
used
it must be ensured that
these
grounds are, and will remain, at the same potential.

.2
AC SUPPLY VOLTAGE
Before switching
on the equipment ensure that
the a.c. voltage selector
is set to
correspond
with the local a.c. supply voltage.
Never
operate the equipment from a line voltage or
frequency
in excess of that
specified for the voltage selector setting
used.
Otherwise, the insulation of
internal
components may break down and cause
excessive leakage
currents.
1.3
FUSES
Before switching on the equipment check that the fuses accessible from the
exterior of the equipment are of the correct rating. The rating of the a.c. line fuse
must be in accordance with the voltage of the
a.c.
supply.
Should any fuse continually blow, do not insert a fuse of a higher rating. Switch
the equipment off, clearly label it "unserviceable" and inform
a
service
technician.
