Always switch off the mains power supply before working on the
electrical or mechanical part of the system. Wait for the warn-
ing lights on the control panel to go out before opening the ap-
pliance. The capacitor of the direct current intermediate circuit
remains charged with dangerously high voltage even after the
mains power has been turned off.
Only rmly cabled mains connections are admissible. The appli-
ance must be earthed (IEC 536 class 1, NEC and other applicable
standards).
THE SYSTEM MUST BE CORRECTLY AND SAFELY EARTHED!
It is recommended to install a differential switch to protect the
system, which must have correct dimensions, such as: Class
A with adjustable leakage current, selective, protected against
sudden tripping.
The automatic differential switch must be marked with the fol-
lowing two 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.
8.1 Power supply connection
After having wired the power supply cable as shown in Figure 3, connect
it to the board as shown in Figure 4.
Before supplying power to the circulator, ensure that the cover of
the EVOPLUS SMALL control panel is perfectly closed!
