Do NOT extend the power cable
Power cable - open array scanners
The 48" 4 kW open array scanner is intended for use on ships’ DC power
systems operating in the 10.7 to 44 V DC range (that is, 12 V, 24 V and 32 V
systems). 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.

CAUTION
Do not use the 48" Open Array Scanner with an SL70 or Autohelm 7”
LCD display unit. Failure to observe this may result in permanent damage
to the display unit.

to the display unit.
12 V systems
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 rated at 20 A MUST be included in the power cable.

All power connections must be of high quality to minimise 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.
