ELECTRICAL INSTALLATIONS
Connect the power wires and ground to the appropriate regulator terminals. Custom Controls with ground
conductor section less 10mmq require double earthing connection obtainable through the grounding of the
aluminum heatsink.
To avoid dispersion currents, the motor earth cable must be connected to the appropriate motor terminal
ground.
We recommend to connect to the machine’s safety circuit any thermal motor klixon in order to remove the
control power supply and protect the motor with maximum efficiency.
If the length of the motor cable exceeds 5 metres, we advise to use shielded cable. The control load can
consist of several engines provided the sum of the rated currents of the motors is less than 20% of the
rated current of the control. We recommend not introduce any electromechanical device on the motor
cable. If the control cable length exceeds 2 metres, use shielded cable, connecting the shield only on the
regulator. Ensure that the control 0 volt is not connected to earth.
If the length of the power, motor and control cables exceeds 10m, make sure they are separated by at least
0.3 metres to avoid creating a coupling effect.
If controls are set up in environment subject to electromagnetic disturbance, they should be housed inside a
suitable metallic enclosure. In order to prevent the formation of condensation and regular working also
cold temperature it is recommended you insure a constant power supply, avoiding turning it off
continually.
All connections wires must resist to an 80°C working temperature.
Avoid routing any electric wires near the copper coils on the filter, use the suitable plastic
support! Tighten all wires on control and power terminal boards fully down, avoiding
protrusion of the multi-stranded wire.
Do NOT touch the electronic equipment when the power line is on!
During voltage insulation tests disconnect the regulator power lines In/Out.
Use a true RMS tester to measure the current or voltage values.
In the event that regulator operation failure could cause damage to objects or physical
injury, it is the responsibility of the installer to add devises or systems that protect against,
or warn of, control failure.
To protect the power line and the regulator, the installation technician must install
extra-rapid
semiconductor fuses upstream of the power supply adequate for the load and with a value of I²t less
than the value given in the table below
. If a differential circuit breaker is installed, it must be of the
delayed action type.

To connect wiring to the spring terminals, apply leverage with a screwdriver on the lever or on the upper
hole to open the terminal.
