I 4 Installation
The Below Decks Equipment (BDE) should be located within the range of
the 50 m ADE / BDE cable and mounted with the cable connectors
pointing downwards on a flat vertical surface (wall) which is sheltered
from the elements (e.g: water).
The wall must be able to support the weight (1.5 kg,  lbs) and have
adequate space for the unit that is 250 mm (9.8 in.) x 190 mm (7.5 in.) x 55
mm (2.16 in.).
Space must be provided for the following cables:
• Power cable
• ADE /BDE cable
• Data cable
• Handset ( max.)
The cables connected internally to the BDE (e.g.: power, cable from ADE)
should be attached to the BDE housing with strain reliefs. It is also
advisable to protect the cable connection with external strain relief. The
cables that connect to the data and handset ports must have external
strain relief.
Power to the BDE may be AC or DC. AC power suitable for connecting the
AC Power Supply Unit (PSU) should be: 110/240V, 50/60Hz. DC power
should be: 2 wire plus earth nominally 12 or 24VDC capable of supplying
50W continuous, 80W for .25 seconds at switch-on.
If appropriate, use the provided cable when connecting the AC PSU to the
BDE. Otherwise, the installer should provide a standard IEC cable with the
appropriate country plug. The 2-way connector should be connected to
the "power in + and –" terminals within the installation section of the
BDE.
When using DC power the installer will need to provide a suitable 2 wire
+ earth cable capable of providing 12/24VDC nominal (11V min, 2V max)
and 50W continuous / 80W for .25 seconds at switch-on at the BDE. The
positive and negative wires must be terminated using the connector
from the AC PSU (provided). The 2-way connector should be connected to
the "power in + and –" terminals within the installation section of the
BDE. The earth should be connected to the earth tag inside the
installation area of the BDE.
