The electric connection has to be performed by a qualified electrician in
compliance with the national regulations.
Follow the safety regulations and
installation regulations of your country.
Connection to the power supply must be carried out in compliance with the
standards via a fixed power cable which is fitted with a plug-type connection
or
an all-pole isolating switch with a minimum contact opening of 3 mm.
The circulator belongs to class II and therefore grounding is not necessary. The circulator does not require any
external protection of the motor. Compare the frequency and the voltage of the mains with the rating data. All
electric information concerning the A1:G413 is on the signaling plate. The connection cord must be laid in such a
way as it cannot come in contact with the hosing or the motor body. In case of use of the circulator with fluids at a
temperature higher than 70 °C, use a connection cord resistant to high temperatures.
5. ELECTRIC CONNECTION
Fig. 5.1
1.
Connect the power supply conductors to the terminals according to the diagram given in Fig. 5.1, from A to C.
When using three-pole cables, remove the end of the grounding cable.
2.
Insert the terminal board in the proper seat, connecting the blue wire (neutral) with letter N and the black/brown
wire (phase) with letter L. (Fig. 5.1.D).
3.
Screw the two screws (Fig. 5.1.E - The tightening torque of the screws must correspond to a maximum value of
0,3 Nm).
4.
Tighten the sealing nuts to the fairlead (Fig. 5.1.F - The tightening torque must correspond to a maximum value
of 2 Nm).
5.
The LED light, if lighted, indicates that the power supply is present. (Fig. 5.1.G).
