maximum power cable extensions are given in the table below. These figures relate to the total cable extension, from the end of the supplied

1.5m power cable to the system battery terminals. Do not exceed these lengths as unreliable operation may result.

Note: If the required extension results in unacceptably large diame- ter cables, use two or more smaller gauge wires to achieve the re- quired copper wire cross-section. For example, using two pairs of 2 mm2 is equivalent to using two single 4.0 mm2 cables.

24 V and 32 V systems

These systems are less sensitive than 12 V systems to voltage loss in the power cables. However, it is still necessary to use adequate cables to prevent excessive power loss. The table below gives the recommended wire gauge for different power cable extension lengths. Raytheon recommends that power is fed directly from the output of the battery isolator switch via its own dedicated cable system.

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.

Note: If the required extension results in unacceptably large diame- ter cables, use two or more smaller gauge wires to achieve the re- quired copper wire cross-section. For example, using two pairs of 2 mm2 is equivalent to using two single 4.0 mm2 cables.
