Stuart Turner Monsoon U1.5 bar Twin Installation Instructions Manual page 11

The motor fitted to this pump is suitable for a 230/1/50Hz supply. It is thermally
protected by an integral auto resetting thermotrip for your safety and rated for the duty
listed in the technical specification section.
Electrical Connection
The motor is provided with a factory fitted supply cord. This must be permanently
connected to the fixed wiring of the mains supply. Means for disconnection must be
incorporated in the fixed wiring in accordance with the wiring rules.
A suitable method of connection would be via a double pole switched, fused connection
unit complying with BS 1363-4, protected with a fuse (see fuse section).
The connection unit should be mounted in an easily accessible position and should be
labelled if confusion is possible, to allow easy identification of the pump isolating switch.
Earthing
This appliance must be earthed via the supply cord, which must be correctly connected
to the earth point located in the terminal box.
Copper or metallic pipework must have supplementary earth bonding where the
continuity has been broken by flexible hoses or plastic components. Adjacent suction and
delivery pipes should be fitted with earthing clamps to BS 951 and connected with
earthing wire size 4 mm² (Fig. 11). A standard kit is available from Stuart Turner (Part No.
17044).
Certain installations may require additional earthing arrangements such as equipotential
bonding. Reference should be made to the relevant regulations concerning this subject to
ensure compliance.
