ELECTRICAL INSTALLATION
AquaProbe is usually supplied with an integral cable and
potted terminal box. The cable is fitted with the necessary
plugs for connection to the AquaProbe transmitter. In some
cases however the lead assembly (complete with plugs) is
supplied unattached to the AquaProbe and connections to the
probe head are necessary. A battery may be supplied, with
integral plug and connector. If required an optional cable, with
the required connector, is available for any output function.
