If you are mounting the scanner on the mast of a sailboat, and will need to unstep the mast, you should install a suitable junction box inside the boat.

On a radome scanner, the junction box should provide an 11- or 13- way terminal strip, depending on the number of power cores in your cable, with a 10 A rating. Also, you should keep the length of the un- screened coaxial cores to less than 30 mm to maintain EMC conformance.

On an open array scanner, the junction box should provide a 13-way terminal strip with a 20 A rating for power cores. It is essential that all 4 power cores are connected and that the connection is of very low resistance as considerable power passes through this connection. Also, you should keep the length of the un-screened coaxial cores to less than 30 mm to maintain EMC conformance.

Inter-unit cable

The inter-unit cable entrance is at the rear of the scanner unit. If the unit is mounted on a hollow mast the cable may be run inside the mast and then fed through the radar’s cable entrance. Make sure that the cable does not chafe where it enters and exits the mast.

Note: Route the cable from the display up to the scanner, since this will require the smallest clearance hole.

CAUTION:

The display connector on the inter-unit cable is a moulded plug that cannot be replaced. DO NOT remove this moulded plug.

The inter-unit cable, for connecting the scanner to the display unit, depends on your scanner package as follows:

Table 1-3: Inter Unit Cables required for each Scanner Type

Scanner Package	Inter-Unit Cable

2D (US)	10 m light (2 power cores)

2DE (European)	15 m light (2 power cores)

4D	15 m heavy (4 power cores)

5S, 7S (4 kW) and 9S, 11S (10 kW)	15 m heavy or radar arch kit
Note: All 10 kW systems require a	(5 m + 10 m extension)
minimum of 24 V.	25 m heavy (24/32 V systems only)

The minimum bends permitted are:
Minimum bend, light cable	60 mm (~2.5 in) radius
Minimum bend, heavy cable	82 mm (~3.75 in) radius
