5.3. Electrical connection
The electrical connection must be made by a
qualified electrician and comply with applicable
local standards.
Complete electrical information about the circulator is
given on the data plate.
Power supply network
Use a three-conductor cable (3 x 1,5 mm2 H05 VVF) to
connect mains power to the corresponding terminals
of the circulator: phase (L), neutral (N), and earth ( )
(see FIG. 4).
The power cable must not touch the pipe or the
pump; make sure that it is away from any
moisture.
Check line protection and the mains voltage and
frequency.
The circulator must be connected to the mains via a
switch with an opening distance, on each pole, of at
least 3 mm.
The power outlet must have an earthing contact.
The motor need a protection by contactor /
discontactor.
After making the electrical connections, put the motor
housing.
