ELECTRIC CONNECTIONS
The instrument meets EMC standards (electromagnetic compatibility) however correct installation is fundamental in order not to
compromise its performance as well as operation of the instruments found nearby. For this reason, the instrument's cables must
be at least:
• 1 m away from cables that carry radio signals (except for SSB radio transmitters).
• 2 m away from cables that carry SSB radio transmitter radio signals.
Follow the rules given below when doing the electrical work for the instrument:
• Turn on power to the instrument only after making and checking that all the electric connections are correct.
• Put in a switch to turn on and shut off the instrument.
• Install a 125 mA fast blow fuse on the instrument's power supply line.
• Use the supplied cable or an unscreened cable with a braided pair (cross section 0.25/ 0.35 mm
100/150 ohm) for data interface connection (CANH and CANL signals).
• The data cable cannot be more than 100 meters long.
A terminal block is found at the back of the instrument for connection of the various electric signals.
