Supply voltage:
• 12 VAC/DC (±10%)
• 24 VAC/DC (±10%);
• 100... 240 VAC (±10%).
Power Consumption:
5 VA max.
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.
To avoid electrical shock, connect power line at
the end of the wiring procedure.
3.
For supply connections use No 16 AWG or larger
wires rated for at last 75 °C.
4.
Use copper conductors only.
5.
For power supply the polarity is a do not care
condition.
6.
The power supply input is NOT fuse protected.
7.
Please, provide a T type 1A, 250 V external fuse.
