6.1) POWER
SUPPLY
The instrument doesn’t work without power supply.
Before powering the instrument verify always to insert the right value (85-265 Vac/dc
standard; 20-60 Vac/dc OPTION).
The instrument is equipped with an internal protection fuse on the power supply, type 5x20mm
dimensions, 315mA 250V, Fast (i.e. Schurter FSF). If the instrument is off, with presence of power
supply, it’s necessary to verify the internal fuse.
In case of fuse replacement, disconnect the instrument from the power supply, current plus voltage
input and all input/output sections (digital input/output, analog output, RS485/RS232 serial port etc.),
then open the rear door and change the fuse that is near the power supply connector (in the low part
of instrument). Only a qualified and authorized technical person can change the fuse. Extract the
interrupted fuse using a screwdriver and with a plier insert the new fuse.
The instrument's power supply does not require any earth connection.
