Страница: 41 / 64

Making connections
Follow the steps below to connect the cable(s) to your product.
1. Ensure that the vessel's power supply is switched off.
2. Ensure that the device being connected to the unit has been installed in accordance with the
installation instructions supplied with that device.
3. Ensuring correct orientation, push the cable connector fully onto the corresponding connector
on the unit.
4. Turn the locking collar clockwise to secure the cable.
9.2 Power requirement
The HD Digital Radome Antenna must be supplied with power by either a 12 V dc or a 24 V dc supply.
Do NOT connect to a 32 V system.
If you are replacing an existing Radome scanner with an HD Digital Radome Antenna, you must also
replace any existing cable with the appropriate digital cable, as described in section
2.7 Cables
.
If you connect to the power supply via an isolator switch, the minimum switch rating is:
• For a 12 V system, 20 A.
• For a 24 V system, 15 A.
Warning: Positive ground systems
Do not connect this unit to a system which has positive grounding.
Power Supply Protection
The power supply must be protected by a suitable thermal circuit breaker or fuse, fitted close to the
power source. The protection requirements are the same for both 18” and 24” HD Digital Radome
Antennae, and are as follows:
• In a 12 V system, protect the power supply with either a 10 A thermal breaker, or a 15 A fuse.
• In a 24 V system, protect the power supply with either a 5 A thermal breaker, or an 8 A fuse.
Power cable lengths
The total permitted lengths of power conductor run (i.e. power cable plus cable extension) from the
power source to the HD Digital Radome Antenna are :
• for 12 V systems, 20 m (65 ft)
• for 24 V systems, 35 m (115 ft)
If you want to connect to a 12 V power system but a total power conductor run of more than 20 m
is necessary, the use of a suitable voltage converter is recommended, to convert the 12 V supply
voltage to 24 V, and thus enable you to extend the run up to 35 m. We recommend using a converter
with a minimum 200 W output capacity.
Grounding requirements
These grounding requirements are applicable for Raymarine equipment supplied with a separate
drain wire or screen.
• The product power cable drain conductor (screen) must be connected to a common ground point.
• It is recommended that the common ground point is a bonded ground, i.e. with the ground point
connected to battery negative, and situated as close as possible to the battery negative terminal. If
a bonded ground system is not possible, a non-bonded RF ground may be used.
