Installation

HF SSB transceiver reference manual 2-11

Power supply

Ensure that the power supply to operate your transceiver is

12V DC.

Power can be provided by either a 12V battery (for mobile

stations) or a suitable power supply connected directly to the

mains (for fixed base stations).

All installations should be checked by a qualified technician

before power is applied to the transceiver.

The heavy duty six metre length of power cable, which is

supplied with the vehicle mounting cradle for mobile

stations, minimises the voltage drop between the battery and

transceiver during transmission. Do not use a thinner cable

than this.

Protect all cables from sharp edges and mechanical

abrasions.

We recommend that a suitable cartridge fuse (32 Amp—

accessory code 711) is fitted in the active wire, close to the

battery. This will protect the power cable from risk of fire

should damaged insulation touch the vehicle chassis. Do not

use normal glass in-line automotive fuses. The transceiver is

fitted with adequate internal protection.

Connect the power cable between the transceiver and the

battery or the AC power supply.

In extended control installations where the power and

control cables are long and follow a common path, keep

the cables separated by a minimum of 200mm. The

cables can be closer together for short distances, for

example, to pass through the same hole in the bulkhead.

Failure to observe this warning will cause distortion of

the transmitted audio signals.
