Line power connection

The SourceMeter operates from a line voltage in the range of 85 to 250V at a frequency of
50 or 60Hz. The SourceMeter will also operate at 400Hz; accuracy specifications are not guar-
anteed however. Line voltage and line frequency are automatically sensed. Therefore, there are
no switches to set. Check to be sure the operating voltage in your area is compatible.
CAUTION
Perform the following steps to connect the SourceMeter to line power and turn it on:

To prevent electric shock, power must be off when connecting the Remote
PreAmp to the mainframe. If you wish to connect the Remote PreAmp at
this time, proceed to Section 2, Connecting Remote PreAmp to the
mainframe. Important safety precautions are included with the connection
procedure.
During the power-up, voltage spikes may appear on the terminals of the
SourceMeter. These voltage spikes could be at hazardous levels (>42.4V
peak) and could damage sensitive DUTs. Never touch external circuitry or
the test leads when powering up the SourceMeter. It is good practice to
always disconnect DUTs from the SourceMeter before powering up the
unit.
To prevent electric shock, test connections must be configured such that
the user cannot come in contact with conductors or any DUT that is in
contact with the conductors. Safe installation requires proper shields, bar-
riers, and grounding to prevent contact with conductors. Operator protec-
tion and safety are the responsibility of the person installing the product.
Operating the instrument on an incorrect line voltage may cause damage,
possibly voiding the warranty.
Before plugging in the power cord, make sure the front panel power switch is in the off
(0) position.
Connect the female end of the supplied power cord to the AC receptacle on the rear
panel.
The power cord supplied with the SourceMeter contains a separate ground
for use with grounded outlets. When proper connections are made, instru-
ment chassis is connected to power line ground through the ground wire in
the power cord. Failure to use a grounded outlet may result in personal
injury or death due to electric shock.
Turn on the instrument by pressing the front panel power switch to the on (1) position.
