Connections overview
1. Alternate power connector
2. Network / PoE connector
The alternate power connector is required when
connecting to a network which does not support
Power over Ethernet PoE. The alternate power
connector must be connected directly to a power
supply.
Note: Do not connect the alternate power
connector to a SeaTalkng network.
Note: Only use one power source. There is no
need to connect the alternate power connector
when the keypad is being supplied PoE.
Alternate power connection
When the keypad is not supplied Power over
Ethernet (PoE) then the alternate power connection
should be connected directly to a 12 V dc or 24
V dc power supply.
1. Keypad
2. Right angled power cable
3. Black negative wire
4. Red positive wire
5. Ground / shield wire
Warning: Product
grounding
Before applying power to this product,
ensure it has been correctly grounded,
in accordance with the instructions
provided.
In-line fuse and thermal breaker
ratings
The following in-line fuse and thermal breaker ratings
apply to your product:
In-line fuse rating
Thermal breaker
rating
1 A slow blow 1 A (if only connecting
one device)
Note:
• The suitable fuse rating for the thermal breaker
is dependent on the number of devices you are
connecting. If in doubt consult an authorized
FLIR dealer.
• Your product’s power cable may have a
in-line fuse, if not then you can add an in-line
fuse to the positive wire of your product’s
power connection.
Grounding — Dedicated drain wire
The power cable supplied with this product includes
a dedicated shield (drain) wire for connection to a
vessel's RF ground point.
It is important that an effective RF ground is
connected to the system. A single ground point
should be used for all equipment. The unit can be
grounded by connecting the shield (drain) wire of
the power cable to the vessel's RF ground point.
On vessels without an RF ground system the shield
(drain) wire should be connected directly to the
negative battery terminal.
The dc power system should be either:
• Negative grounded, with the negative battery
terminal connected to the vessel's ground.
• Floating, with neither battery terminal connected
to the vessel's ground
Warning: Positive ground
systems
Do not connect this unit to a system
which has positive grounding.
Flush mounting the keypad
Flush mounting provides a sleek installation where
the product and dash are with only the
buttons and Rotary controller protruding from the
dash. Flush mounting requires the mounting surface
to be rebated.
1. Check the selected location for the unit. A clear,
area with suitable clearance behind the panel
is required.
2. Before modifying the mounting surface, refer to
the dimensions supplied in this document to
3
ensure there is enough space for the unit and
all cables.
3. Fix the supplied mounting template to the
selected location, using masking or self adhesive
tape.
4. Drill 4 holes as indicated on the mounting
template to accept the .
5. Using a suitable hole saw (the size and position
is indicated on the template), make a hole in
each corner of the cut-out area.
6. Using a suitable saw, cut along the inside edge
of the cut-out line.
7. Using a Router, follow the Flush mount rebate
line, to cut out a rebate to the rebate
depth, as indicated on the template.
8. Ensure that the unit into the removed area
and then remove rough edges.
9. Place the supplied gasket onto the rear of the
keypad, ensuring the mounting holes are aligned.
10.Connect the relevant cables to the unit.
11.Place the keypad into the rebate and secure
using the provided.
Note: The appropriate tightening torque and drill
bit size to use depends on the thickness of the
mounting surface and the type of material it is
made from.
Note: The supplied gasket provides a seal
between the unit and a suitably and stiff
mounting surface or binnacle. The gasket should
be used in all installations. It may also be
necessary to use a marine-grade sealant if the
mounting surface or binnacle is not entirely
and stiff or has a rough surface
Surface mounting the
keypad
Surface mounting provides a uniform installation
where the products protrude, usually by the thickness
of the bezel, from the mounting surface.
