Cable Connections - COBHAM Satcom EXPLORER 540 User & Integrator's Manual

2.3 Cable connections

There are no external connectors on the EXPLORER 540. All cable connections on the
EXPLORER 540 are made during installation.
Remove the 8 screws from the small cover at the back
of the terminal and take off the cover. Then connect
the cables to the relevant terminals or connectors.
Two standard cable glands and two C1D2 approved
cable glands with gaskets are provided for the cables.
Note
After making all connections, remount the 8
screws for the small cover and tighten to torque 0.5 Nm/ 4.5 lbf in.
See Interfaces specifications on page A-2 for specifications and pin-out for the
interfaces.
See the section below for instructions specific to the DC input.
See the EXPLORER 540 Installation guide for details on how to connect cables.
Note
2.3.1 Instructions for power input
Use one of the following power sources (connected at installation, see the Installation
guide):
• PoE+ via the LAN interface
• 12 or 24 VDC nominal, e.g. from a battery (absolute maximum rating 10.5-32 VDC)
Note
Requirements for DC input
Observe the following requirements for connecting to the DC input:
• Power supply: Fuse the power source with a fuse rated 6 A when the input voltage
range is 10.5 VDC to 16 VDC; and rated at 3 A when the input voltage range is
>16 VDC to 32 VDC.
• Cable requirements:
• Wire size 1.5 mm
• Torque for screw terminals: 0.5 N m/ 4.5 lbf in
98-148232-K
For C1D2 operation, use C1D2 approved
cable glands, e.g. the supplied cable glands
with Cobham Part no 32-207214-612.
Note that a LAN connector cannot pass
through the C1D2 approved cable gland.
If you are going to use the optional EXPLORER 540 Cellular Modem, connect
the modem to the USB connector and to DC power in the interface enclosure
of the EXPLORER 540. For details see the installation guide included with the
EXPLORER 540 Cellular Modem.
When you use the EXPLORER 540 with the cellular modem, a separate DC
supply is required instead of PoE in order to supply sufficient power for the
modem as well as the EXPLORER 540.
