g kJ <br /> INSTALLATIONPROCEDURES <br /> 5.ELECTRICAL CONNECTION <br /> ANote:The pump must never be connected to a capacitor orto another type of <br /> control box other than a CU 300 or CU 301. <br /> The pump must never be connected to an external frequency converter. <br /> 5upply voltage: l x 100-115V or 1 x 200-240 V+6%/-10%,50/60 Hz. <br /> The current consumption can only accurately be measured by means of a <br /> true RMS instrument.If other instruments are used,the value measured <br /> will differ from the actual value. <br /> The SCE pumps can be connected to a CU 300 or CU 301 status box. <br /> Motor protection <br /> The motor has built-in automatic thermal overload protection and <br /> requires no additional motor protection. <br /> Connection of motor <br /> The motor can be connected directly to the main circuit breaker. <br /> Start/stop of the pump will typically be done via a pressure switch,see <br /> Figure 5. <br /> Note-.The pressure switch must be rated for the maximum amps of the <br /> specific pump size. <br /> WARNING! <br /> Reduced risk of electric shock during operation of <br /> this pump requires the provision of acceptable <br /> grounding. If the means of connection to the supply <br /> • connected box is other than grounded metal <br /> conduit,ground the pump back to the service by <br /> connecting a copper conductor,at least the size of <br /> the circuit supplying the pump. <br /> 10 2-Wire Pump OuickDisconnect g <br /> with Ground Single-Phase 2-Wire <br /> j i <br /> Wiring Diagram for <br /> Grundfos Motors <br /> Pressure <br /> Switch <br /> Black Making the Wiring Connections <br /> Black <br /> Green <br /> capacitor <br /> NEVER be connected to a • • <br /> submersible pump. <br /> Pump&Motor <br /> 5 :=,._-;.: i3. -_-�"a=te; Figure 5 <br />
