Chapter 3: Installation 29
Extension cable
If an extension power cable is required, please note the following:
• The wire gauge used may be affected by the scanner type.
• To minimize voltage drops, use large gauge cable.
• Use the supplied power cable to connect to the display unit. Then use a suitable
connector block to connect the free end to the extension cable, taking particular
care to ensure the correct polarity.
• The maximum length of an extension cable is dependent on the multi-strand cable
being used and the voltage of the system:
Note:
For further information on power extension cables please refer to the relevant scanner
handbook or relevant product pages on our website .
Fuse, circuit breaker and switch ratings
Do not fit switches or circuit breakers in such a way that power may be removed from
part of the E-Series networked system while leaving the rest of the system running, as
this may result in unit malfunction.
SeaTalk/Alarm out cable
The SeaTalk cable is supplied with stripped tails. These should be connected to your
existing equipment using either the cable splicers supplied or by using a standard
screw terminal block.
