5  ELECTRICAL CONNECTION 
 
The electric motor is equipped with a terminal strip. Like all electrical connections, the external motor 
control must be connected properly by a qualified electrician.  
 
Work  on  electrical  and  electronic  components  of  the  system  may  only  be  per-
formed by a trained electrician or otherwise appropriately trained personnel under 
the guidance and supervision of a trained electrician in accordance with the appli-
cable electrical and electronic regulations. 
Fuses  do  not  protect  the  motor  from  overloads;  they  only  protect  the  electrical 
supply lines or switching systems from damage in event of a short-circuit. 
 
 
The electric motor must always be protected with a motor protection circuit breaker that must be set to 
the rated current shown on the type plate depending on the motor wiring. Only motor protection circuit 
breakers certified according to the following standards may be used: IEC, UL, CSA. 
 
Set the motor protection circuit breaker to the correct value, never above the max. 
rated current according to the type plate. 
 
 
 
It is recommended that the corresponding electrical control for the separator or for the separator and the 
submersed motor pump be purchased from FAN since it will be already adapted to the corresponding 
drive motors. 
 
 
Ensure the correct rotation direction of the auger shaft when making the electrical 
connection! 
 
 
 
 
In forward motion, the auger shaft turns counterclockwise 
(as  viewed  from  the  output  regulator  toward  the  geared 
motor). 
 
 
 
 
If this is not the case, two of the current-carrying conduc-
tors at the geared motor connection or in the switch cabinet 
must be swapped.
