ELECTRICAL CONNECTIONS

To ensure operator safety and to prevent damage to the components while connections are being
made, or when the radio card is being inserted, the control unit absolutely must not be powered on.
For power cords, motor lines, flasher/courtesy light line, and electric lock, use a cable with a cross-
section that is suitable for the length (minimum 1.5 mm2).
For auxiliary power supplies, controls and safety contacts a minimum section of 0,5 mm2. When
the control cables are very long (more than 30 m), de-coupling is suggested using relays at the
control unit.
If a fuse trips, after removing the cause, replace it with another one of the same type. Install the
various safety devices, limit switches, photocells, sensitive rib, stop button.
If one or more of the safety devices are not installed, the corresponding terminals must be short
circuited with the controls common.
All contacts N.C. Assigned to the same input must be connected in series.
All contacts N.O. Assigned to the same input must be connected in parallel.
Provide disconnecting devices in the power supply network in accessible places.
For the power supply of the control unit, there must be an external disconnecting switch (not includ-
ed), independent and properly sized.
