412 ENVOY™ TRANSCEIVER REFERENCE MANUAL
Most Codan power supplies can use an external battery as an alternative power supply
in the event of an AC mains failure. Codan recommends the use of the Standby Battery
Cable Kit (Codan part number 15-00702) for easy and correct installation of the
standby battery. The cable from this battery must be able to carry the full supply
current, so it must be of correct size.

Protecting the cables
Physical protection
Protect all the cables from sharp edges and mechanical abrasions. Cables that pass
through panels or walls must be protected by grommets. Such holes need only be large
enough to allow the end of the cable with the smaller connector to pass through.
Removing a connector should be a last resort. Externally, the cable and connectors
need to be weatherproofed using self-amalgamating rubber tape.
CAUTION: Removal of factory-fitted connectors may cause cable or connector
faults.
CAUTION: Crimp-style coaxial connectors for vehicle installations should be
avoided because they are susceptible to mechanical damage and are not
weatherproofed.
NOTE: Any cabling under carpet or floor mats should be clear of foot traffic.
Electrical protection
The transceiver is provided with adequate internal protection. The transceiver supply
is also fitted with adequate protection.
If a battery is used, Codan recommends that a suitable cartridge fuse (32 A, Codan
part number 15-00711) is fitted in the positive wire, close to the battery. This protects
the power cable from risk of fire if damaged insulation should touch surrounding
metalwork.
As the fuse is not included to protect the transceiver circuits, it should be of large
physical and electrical size to eliminate the possibility of voltage drops across the
fuse.
WARNING: Do not use normal glass in-line automotive fuses.
