Electrical Requirements
Before attempting to power up the unit for the first time, the following
precautions must be followed:
Have a qualified electrician verify the wall socket that will be used is
properly polarized and properly grounded.
Set the mains selector tumbler to the voltage that matches the power outlet
AC voltage.
Verify the correct rated fuses are installed according to the fuse marking
on the rear panel.

Power Supplies
AC power is supplied through the rear panel input power connector that
provides in-line transient protection and RF filtering. The input power
connector contains the fuses and the switch to select series or parallel
connection of the transformer primaries for operation at 100VAC, 120VAC,
220VAC or 240VAC. The product is shipped with the setting on 110V.
Please make sure you select the right setting according to your AC voltage
level. Also, please make sure you insert the right fuses. The product is
shipped with a spare of fuses for the 220VAC/240VAC settings.
CAUTION
Permanent damage will occur to the power meter if the input
power connector settings are at either 100 or 120VAC and
applied power is above 180VAC RMS
WARNING
To avoid electrical shock hazard, connect the instrument to
properly earth-grounded, 3-prong receptacles only. Failure
to observe this precaution can result in severe injury.
