PRE-INSTALLATION <br /> N CHECKLIST <br /> 3. INSTALLATION POSITIONS <br /> Positional requirements: <br /> The pump is suitable for vertical as well as horizontal installation, <br /> however,the pump shaft must never fall below the horizontal plane,see <br /> Figure 4. <br /> l <br /> Allowed <br /> Figure 4 <br /> If the pump is to be installed <br /> horizontally,e.g.in a tank,it is <br /> --- recommended to fit it in a <br /> flow sleeve. <br /> Not allowed <br /> i <br /> 4. ELECTRICAL CONNECTION <br /> General <br /> i The electrical connection should be carried out by an authorized electrician in <br /> accordance with local regulations. <br /> Before starting work on the pump,make sure the electricity supply has been <br /> switched off and that it cannot be accidentally switched on.The pump must be <br /> A <br /> grounded.The pump must be connected to an external mains switch. <br /> ' t I <br /> 1 <br /> The supply voltage,rated maximum current and power factor(PF)appear on <br /> the motor nameplate.The required voltage for GRUNDFOS submersible <br /> I MS3/MSE3 motors,measured at the motor terminals,is+6%/-10%of the <br /> nominal voltage during continuous operation(including variation in the <br /> supply voltage and losses in cables). <br /> If the pump is connected to an installation where a Ground Fault circuit <br /> i breaker(GFI)is used as additional protection,this circuit breaker must trip <br /> out when ground fault currents with DC content(pulsating DC)occur. 1 <br /> 4 <br />
