INSTALLATION AND USE MANUAL - REV 001A
2.0 - INSTALLATION
The chain counter meets EMC standards (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 cables must be at least:
• 1 m from cables that transmit radio signals (except for SSB radio transmitters).
• 2 m from cables that transmit SSB radio transmitter signals.
Follow the rules below when preparing the electrical system of the instrument:
• Power the chain counter only after making and checking that all the electric connections are correct.
• Install a switch to turn on and off the equipment; make sure the switch is in a position that can be easily reached so
that, in the event of an emergency, the equipment can be quickly turned off.
• Install a 4A fast-blow fuse on the chain counter power supply line.
• The cross-section of the contactors control and chain counter 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 group.
• The maximum length of CAN extensions must not exceed 100 meters.
• In the boat electrical system, provide for the possibility of controlling the windlass with auxiliary controls.
• Insert the male connector M12 of the power supply cable into the female connector M12 of the instrument (fig. 6).
• Screw the ring nut until it is fully tightened (fig. 7).
