The device is designed to be fixed directly to the wall or on the motor body of the pump. In both cases a specific fixing kit is used. For fixing to the motor body, refer to the specific quick guide for the swing. To fix it to the wall, follow the instructions in the NgDrive instruction manual.
To choose the type of sensor to use, refer to those listed on the control panel if present or on the DConnect APP. The mode of use will depend on the settings made on the control panel if present or on the DConnect APP. The device accepts various types of differential pressure sensors. The cable must be connected on one side to the sensor and on the other to the specific pressure sensor input of the variable frequency drive. The cable has two different terminations with mandatory insertion direction: connector for industrial applications (DIN 43650) on the sensor side and 4-pole connector on the variable frequency drive side.

The pumping groups are divided into:
By twin group we mean a pumping group made up of a single pump body on which two motors are mounted.
By multi-pump group we mean a group made up of several identical pump, motor and variable frequency drive elements. Each element shares both the suction and the delivery. Each pump, before flowing into the delivery manifold, must have a non-return valve.
Twin Group Connections
In twin groups the pressure sensor must be connected to the left variable frequency drive (looking at the group from the motor fan side so that the fluid flow goes from bottom to top). For correct operation of the twin system it is necessary that all the external connections of the input terminal block are connected in parallel between the variable frequency drives respecting the numbering of the individual terminals.
If a banging noise is heard during the switch between turning off one motor and turning on the other, then proceed as follows:

The variable frequency drive accepts the 0 – 5V ratiometric pressure sensor.
The cable must be connected on one side to the sensor and on the other to the specific pressure sensor input of the variable frequency drive.
The cable has two different terminations with mandatory insertion direction: connector for industrial applications (DIN 43650) on the sensor side and 4-pole connector on the variable frequency drive side.

The flow sensor is supplied with its own cable. The cable must be connected on one side to the sensor and on the other to the appropriate flow sensor input of the variable frequency drive.
The cable has two different terminations with mandatory insertion direction: connector for industrial applications (DIN 43650) on the sensor side and 6-pole connector on the variable frequency drive side.

To create a multi variable frequency drive system it is necessary to follow the pumping group creation procedure.
The sensors can be connected to only one variable frequency drive.
Data communication between the variable frequency drives takes place via wireless, however it is recommended to fit the communication cable to strengthen the system in the event of a fault in order to be able to read the sensors even if connected to a faulty or switched off variable frequency drive. For correct operation of the multi variable frequency drive system it is necessary that all the external connections of the input terminal block are connected in parallel between the variable frequency drives respecting the numbering of the individual terminals. The only exception is the disable functionality which can be set on any of the 4 inputs and allows you to disable the variable frequency drive; in this case the command can also be distinguished for each variable frequency drive.
