9.  ELECTRICAL CONNECTIONS 

The electrical connections must be made by expert, qualified personnel. 

 

 

ATTENTION! ALWAYS RESPECT THE LOCAL SAFETY REGULATIONS. 

 

 

Always  switch  off  the  mains  power  supply  before  working  on  the  electrical  or 
mechanical part of the system. Wait for the warning lights on the control panel to go 
out  before  opening  the  appliance.  The  capacitor  of  the  direct  current  intermediate 
circuit remains charged with dangerously high voltage even after the mains power has 
been turned off. 
Only firmly cabled mains connections are admissible. The appliance must be earthed 
(IEC 536 class 1, NEC and other applicable standards). 

 

 

THE SYSTEM MUST BE CORRECTLY AND SAFELY EARTHED! 

 
 

 

It is advised to install a correctly dimensioned differential switch to protect the system, 
type: class A with adjustable leakage current, selective. 
The automatic differential switch must be marked with the following symbols: 

 

 

 

 

–

 

The circulator does not require any external motor protection. 

–

 

Ensure that the supply voltage and frequency are the same as the values indicated on the electrical 
data plate of the circulator. 

 

9.1 

Power supply connection 

 

Before supplying power to the circulator, ensure that the cover of the EVOSTA2, EVOSTA3 control 
panel is perfectly closed!
