24 V and 32 V Systems - 10kW scanners
10 kW open array scanners can use any combination of inter-unit cable up to a
maximum length of 35 m. However, these systems use considerable power and
installations should be planned to minimize all cable lengths. Refer to the tables
on page 1-19,

Power cable

The open array scanner systems are intended for use on ships' DC power systems
operating in the following ranges:
4 kW
10 kW
CAUTION:
Do not use the open array scanner with an SL70, SL70 PLUS, SL70RC
PLUS or Autohelm 7" LCD display unit. Failure to observe this may
result in permanent damage to the display unit.
10 kW open array scanner systems cannot be used directly with
12 V systems; they require a 12 V to 24 V converter rated to 180 W.
Contact your authorized Raymarine dealer or distributor for
details.
Open array scanners draw considerable power from the vessels power source,
especially in high wind speeds. It is essential for reliable operation that the unit is
supplied with a low resistance power cable system, especially when operated
from a 12 V power system.
12 V systems (4 kW scanners only)
Extensions to the supplied power cable must be kept to a minimum and the power
should be fed directly from the output of the battery isolator switch via its own
dedicated cable system. It is recommended that no additional power switch is
included in this power cable.
CAUTION:
The display unit does not include a fuse for scanner power, so an
in-line fuse or circuit breaker MUST be included in the power
cable.
All power connections must be of high quality to minimize their resistance and to
remove the risk of accidental shorts. Recommended maximum power cable
extensions are given in the table below. These figures relate to the total cable
extension, from the end of the supplied 1.5 m power cable to the system battery
terminals. Do not exceed these lengths as unreliable operation may result.
