Connecting electrical system
Regulator is designed to be fed with 230V~,
50Hz voltage. Supply is connected to
terminals L, N, PE.
The electrical system should be:
 three core (with protective wire PE),
 z in accordance with applicable
regulations.
Supply wires must be lead so as their contact
with sensor and other low-voltage cabling is
prevented, additionally, all cables may not
contact surfaces with temperatures that
exceed the cables operating temperature
limits.
The controller has no PE protective connector,
because the controller itself does not require
grounding. PE terminals of the pump, mixer
actuator shall be connected with PE of supply
network, according to periphery instructions
and regulation concerning electric systems.
Connecting mains supply 230V~
to terminals for sensors will
damage the regulator and creates
risk of an electric shock!.
Tips of the connected wires, especially power
leads, must be secured against splitting by
means of insulated clamps, in accordance with
the drawing below:
Securing wire tips: a) - right, b) - wrong.
Fixing the external wires
Electric cables external circuits are predicted
for the installation of surface-mounted. A
concealed external cable outlet should be
provided, as well as protection against the
wire being pulled out, loosened or strained,
using electric cable tray. It is not allowed to
leave any cable leads loose, to roll the excess
wire or to bend the wires into acute angles.
It is not allowed to roll the excess wire or to
leave disconnected cables inside the regulator
housing, as it may lead to damage to the
controller.
Example how to install the cables using
electric cable trays is shown in the figure
below.
