Splicing
If you need to cut the cable, you must splice i t correctly.
Note: DO NOT solder the wires together with only electrical tape for
insulation, as this will result in electrical noise and reduced
operational performance.
To splice the cable, use a metal junction box. The chassis of the
junction box must be grounded, but the cable shielding must
NOT be connected to the junction box ground.
Note: Make sure that you connect the cables 1:1! The red cable in the
“input” cable MUST be connected to the red cable in the
“output” cable etc.
Cable specification
If extension cables are used, these must be supplied by the
installation shipyard. T he following specifications must be
regarded as a minimum:
2x2x0.5mm
2
/ Twisted pairs / Overall braided
Observe the information regarding cable splicing.
Grounding and shielding
Cable shielding must be continuous. The shielding is terminated
in the cabinet and must not be grounded in the junction boxes.
In order to minimize electrical interference, Simrad strongly
recommends that the hydrophone cable is installed in a metal
conduit between the hydrophone and the PI54 cabinet.
