Supply Voltage:
• 24 VAC/DC (±10%);
• 100... 240 VAC (-15... +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 “
ouLd
” (Out 4 Overload) indication.
