manufacturer for system changes and firmware updates, and should
not be used.

socket.
18. F SENSE. SMA Connector. The filter output should be connected to
this socket, via a suitable coupling mechanism. This allows the

amp fuse in the plug or at the distribution panel) to this socket. Two
T12 amp (time delay) fuses are fitted within this connector’s Fuse
