Supply Voltage:
24... 240 VAC/DC (±10%).
Notes: 1.
Before connecting the instrument to the power
line, make sure that line voltage is equal to the
voltage shown on the identification label;
2.
The polarity of the power supply has no importance;
3.
The power supply input is NOT fuse protected.
Please, provide a T type 1A, 250 V fuse externally.
4.
When the instrument is powered by the A01 key,
the outputs are NOT supplied and the instrument
can show the Out 3 Overload indication (
ouLd
).
