ELECTRIC CONNECTIONS
The chain counter meets standard EMC (electromagnetic compatibility). In any case correct installation is
fundamental in order not to affect its performance or interfere with operation of instruments found near it.
For this reason the chain counter must be at least:
• 1 m away from cables that transmit radio signals (except for SSB radio transmitters).
• 2 m away from cables for SSB radio transmitter signals.
Follow the safety precautions and directions given below when making the electrical circuit of the chain
counter:
• Turn on power to the chain counter only after having effected and verified that all the electric
connections are correct.
• Use the snap-on connectors provided to connect the cables to the chain counter.
• Install a switch to turn on and shut off the chain counter; make sure the switch is in a position that
can be easily reached so that, in the event of an emergency, the chain counter can be quickly shut
off.
• Install a 4A fast fuse in the chain counter's power supply line.
• The cross-section of the solenoid/reversing solenoid unit and chain counter's power supply cables
should be adequately sized according to the length of the cables.
• Do not run the chain counter on power delivered from the motors' batteries.
• Use an unscreened cable with twisted pair (cross-section area 0.25/ 0.35 mm
2
AWG 22/24, imped-
ance 100/150 ohm) for the data interface connection (CANH and CANL signals).
• The data cable should not be more than 100 meters long.
• The boat's electrical system should allow other switches to operate the windlass.
