Mains filters

Mains filter IN 50A three-phase
Mains filter OUT 10A three-phase

Mains filter OUT 18A three-phase
For correct operation the mains filter must be installed close to the ACTIVE DRIVER!
The ACTIVE DRIVER is already provided with current protections. If a thermal magnetic cut-out is installed
on the line, this must have a capacity suited to the pump used.
The connection of the line to the ACTIVE DRIVER must include the earth line. The total earth resistance
must not exceed 100 Ohm.
A RCCB should be installed to protect the system, which should be suitably sized, as follows: Class A
(AS for models with three-phase power supply), with selective adjustable current dispersion, protected
against inadvertent activation.
The automatic differential switch must be marked with the following two symbols:

HYDRAULIC CONNECTIONS
Always install a check valve on the pipe upstream from the ACTIVE DRIVER.
For the purposes of operation of the ACTIVE DRIVER it does not matter whether the valve is fitted on the
suction or on the delivery of the pump. The hydraulic connection between the ACTIVE DRIVER and the
electric pump must not have any derivations. The dimensions of the pipe must be suitable for the electric
pump installed.
Figure 4
The ACTIVE DRIVER works at constant pressure. This regulation is most appreciated if the
hydraulic system downstream from the system is suitably sized.
Systems made with excessively narrow pipes can cause load losses which the appliance is unable to
compensate for; the result is that the pressure is constant on the device but not on the utility.
