RISK OF FROST: pay attention to the installation site of ACTIVE DRIVER! Take the following
precautions:
If the ACTIVE DRIVER is operative it is absolutely necessary to protect it adequately against frost and to
leave it constantly powered. If it is disconnected from the power supply, the anti-frost function is no longer
active!
If the ACTIVE DRIVER is not operative it is necessary to turn off the power supply, disconnect the
appliance from the pipe and completely empty out all water left inside.
It is not sufficient just to remove pressure from the pipe, because some water is always left inside.
1.8 GENERAL CHARACTERISTICS
ACTIVE DRIVER is an innovative system for pumps, which maintains constant pressure on variation of
flow rates, regulating pump speed accordingly.
The ACTIVE DRIVER comprises an inverter, a pressure sensor and a flow sensor.
The ACTIVE DRIVER is equipped with 3 inputs and 2 outputs.
Figure 5 shows the connection diagram of the outputs, terminal J14.
Figure 6 shows the connection diagram for 2 ACTIVE DRIVER units, for the exchange and dialogue
functions.
Figure 7shows the connection diagram of the utility input terminals J22.

CAUTION: In the case of interconnection cables exceeding the length of 1 m, use a twisted
cable (with twisted pair), one pair for pins 1 and 3 and another pair for pin 2.
CAUTION: Strictly observe the connection sequence between the two appliances! (see fig.2)
