Isolation transformer
• When the power on polarity switching function is used, be sure not to
connect the neutral wire on the secondary side of the isolation trans-
former to ground. If it is connected to ground, a ground fault will occur.
• Use a voltmeter or voltage detector to make sure that terminal E [LINE IN]
is at ground potential (approx. 0 V). Failure to make this confirmation
could lead to electric shock or damage the instrument or the equipment
under test.
• When connecting the power cord of the equipment under test to the
[LINE IN] terminal, use a cord suitable for the capacity of the equipment
under test. Using a power cord with another rating may result in fire.
