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 3 m, we suggest using shielded cable, connecting the shield only on the regulator. We suggest don't connect
the control 0 Volt to the Earth.
If the length of the power, motor and control cables exceeds 10 m, 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 80°C working temperature.
Avoid routing any electric wires near the copper coils of 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 responsability of the installer to add devises or
systems that protect against, or warn of, control failure.
Check the position of the voltage change jumper according to the supply voltage available, to the type of
control (see coding paragraph page 3, pos.3) and to the panoramic view of the corresponding card.
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 I² t 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 rectangular hole to
open the terminal (see below the panoramic view cards). The power wires of the XV350K and XV360K regulators
must be crimped to form an eyelet (M6 hole) and the nuts (E10) tightened with a wrench.
