- It is recommended to fit three-phase operators with a safety device consisting of a switch to cut off power to the low voltage circuit.
Connections are in series with the limit switch common terminal (pic. 9). The switch is activated whenever the override spanner is
inserted for manual operations or the operator cover is removed.
Should the limit switches be wrongly connected so that their action opposes the normal travelling of the gate, reverse their connections
in the main board. Change over the live connections, keep the common fixed in the same terminal.
