POWER NET ENERGY MANAGE SYSTEM
Power Net is an analyzer that measures, calculates and gives to a Modbus
master or Power Studio the electrical variables of industrial networks (balanced
or unbalanced). The measure is TRMS using the 3 voltage inputs. The current is
measured by TC current transformers. The parameters are shown in the memory
map table.
This manual is a quick guide to the use and operation of NET POWER. For more
information, you can download the full manual on the website of CIRCUTOR:

Before performing any maintenance, modification, connection,
repair, etc., disconnect the device from the power supply. When
you suspect a malfunction of equipment or protection thereof
shall be immediately put out of service.
1 POWER NET FUNCTION
To view and store the values measured by one or more measurement devices
Power Net network must be connected to software management and acquisition
of data through a bus RS-485 (maximum 32 devices).
Through the Power Power Studio or Scada application software is possible to
configure the device to communicate with the application which will visualize the
values measured by the device, perform graphic and stored historical view.
To communicate Net Power with the management application should check the
communications wiring and equipment installation.
If you use the instrument is not specified by the manufacturer, the
protection of equipment and the user, may be involved.

POWER NET measures in two quadrants. The user does not have to worry
about the direction of the current transformer. The device changes internally
current direction so that they always measured consumed energy.

POWER NET stores in memory the maximum and minimum values without
supply.
3 CONNECTION
As a device that remains permanently connected in an installation, should be
provided with magneto-thermal switch or equivalent to be disconnected. Should
be fitted with fuses GL (IEC 296) or type M of 0.5 ... 2 A.
The section of power cables and measure the equipment must not be less than
1.5 mm ².
Power Net must be installed at the point where you want to measure ensuring
that this point meets the insulation requirements, guaranteeing minimum
electrical safety transformer. Similarly, the characteristics of the measuring point,
meet the specifications of the equipment.
