3.3 Electrical connections
The electrical connection to the Sig.Processor is fairly simple in a normal installation, since
the number of cables to be connected in a standard installation is small. All connections to the
Sig.Processor and to optional Sig. Distributor shall be made with screened cables!
At least four connections shall always be used:
An extremely solid connection is to be made between the metal structure of the hull and
the grounding screw on the outside of the case. The cable area of this connection shall be
at least 10 mm², preferably using copper braid.
The AC power intake cable shall be brought to the 100 / 230 V AC terminals at the
MAIN_1 intake located in the lower left end corner of the Sig.Processor. Connect to L1,
L2 and GND.
The transducer cable shall be connected to terminal numbers 1 - 5 and 37 - 54. Do not cut
the cable. If the cable is cut the warranty will not be valid.
Connect terminals 1 – 5 to the WT connector numbered 1-5.
