Technical Data; Electric Motor - Vetus DWSC04212 Instructions D'installation

3.6 Electrical installation, pump
Check that the voltage stated on the identification plate is the same
as the battery voltage (12 or 24 V).
Consult the wiring diagrams on pages 42 and 43 when connecting
the pump. Extend the connector wires if required. Use good quality
wire connectors together with the right wiring pliers! Make sure that
all electrical connections remain dry under normal conditions in or-
der to prevent electrolysis and corrosion.
The minimum cross-section for the connecting cables is 2.5 mm
(AWG 14). The voltage drop between the battery and the pump
should not exceed 10% of the supply voltage. For a 12 Volt installa-
tion with a total cable length (positive and negative wiring added
together) of more than 19 m use cable with a cross-section of 4 mm
(or more than 50 ft: use AWG 12).
Connect the power supply as shown in the wiring diagram. See draw-
ing at page 26.
A main switch* and a fuse** must be incorporated in the positive ca-
ble.
Make sure the + (plus) and - (minus) connections are made prop-
erly!
Red is +, black is -.
*) The switch must be rated for 15 Amps.
**) Fuse: 10 Amps for 12 Volt system
7.5 Amps for 24 Volt system
The electric motor may become hot when used for a longer period
of time!
Make sure that electric wiring etc. does not get in contact with the
motor housing.
3.7 Electrical installation, level sensor and level gauge
The previously installed tank level sensor (Art. code: SENSOR320)
measures the liquid level. The sensor can be used in combination
with a Vetus level meter.
Note: Not included in the delivery.
