WARNING

When changing the power supply fuse or changing the power
supply voltage, in order to avoid the risk of electric shock accident,
be quite sure first to turn the main switch of the 3522-50 unit off,
and then to remove the power cord.
Moreover, after finishing any operation, before reconnecting the
power cord to the unit, be sure to check that the power supply
voltage value indicated on the voltage selector housed in the power
input socket on the rear panel is in agreement with the actual
voltage value of the power supply line to which you intend to
connect the unit.

Replace the fuse only with one of the specified characteristics and
voltage and current ratings. Using a non-specified fuse or shorting
the fuse holder may cause a life-threatening hazard.
Fuse type:
100 V, 120 V settings: 250 V F1.0 AL 20 mm
× 5 mm dia.
220 V, 240 V settings: 250 V F0.5 AL 20 mm × 5 mm dia.

Before the 3522-50 is dispatched from the factory, it is set to the
power supply voltage used at the destination specified for shipping,
and the specified fuse for that power supply voltage is fitted, along
with an identical spare fuse. If for any reason you intend to power
the unit from a power supply whose voltage is different, be sure to
change the fuse as well as altering the voltage selector setting.

If you intend to use a power supply of a voltage other than the
specified ones for powering the unit, use a fuse and voltage
selector setting as follows:
Actual power supply voltage 110 V : use settings for 120 V
Actual power supply voltage 200 V : use settings for 220 V
Actual power supply voltage 230 V : use settings for 240 V
6.2 How to Change the Power Supply Fuse and Change
the Power Supply Voltage
The power supply fuse for the 3522-50 unit, and the power supply voltage
selector, are housed in the power input socket on the rear panel.
