Mounting and installing the terminal | 32
Interface cabling
All interface cabling connections are made with RJ-45 male connectors which plug into the front of the
interface cards (see “
Interface connections” on page 211).
The cabling to the QJET, DFXO and DFXS interface cards must have a minimum conductor size of
0.4 mm2 (26 AWG).
Power supplies
US and Canada: Installations should be in accordance with US National Electrical Code ANSI /
NFPA 70, and Canadian Electrical Code, Part 1 C22.1.
Warning: Do not apply power to the terminal until you have completed installing
the interface cards and connecting the antenna.
Warning: Before disconnecting the safety earth during maintenance, remove AC
or DC power supply connections, antenna cable and all interface cables from the
terminal.
DC power supply
There are three DC power supplies for the terminal 12 VDC, 24 VDC and 48 VDC.
As the terminal DC input is isolated above ground, the DC power input can be either positive grounded
or negative grounded.

±24 VDC 20.5 to 30 VDC 63 - 180 W 8 A 10 A
±48 VDC 40 to 60 VDC 63 - 180 W 4 A 5 A
Caution: An all-pole switch or DC circuit breaker of the rating shown in the table above must be fitted
between the terminal DC input and the DC power source.
Each terminal or MHSB terminal should have its own separate fuse or DC circuit breaker.
