ELECTRICAL CONNECTIONS
With existing installations, a general check of the state of the wires (section, insulation, contacts) and auxi-
liary equipment (photocells, receivers, pushbutton boards, key selectors, etc.) is recommended.
Tips for correct Installation:
1) The wires entering the control unit, in the sealed box version, should be connected without altering the initial
protection rating IP56 if possible.
2) The cross section of the cables should be calculated according to their length and absorbed current.
3) Do not use a single cable of the "multi-core" type for all the connections (line, motors, controls, etc.) or in
common with other equipment.
4) Use at least two cables for the installation, e.g.:
cable (A) minimum wire section 1.5 sq.mm
cable (B) minimum wire section 0.75 sq.mm
- auxiliaries power supply - controls - safety contacts.
5) When the control cables are very long (over 50 metres), de-coupling is advisable with relays mounted near the
control unit.
should be short-circuited with the common terminal terminal.
7) All the N.C. contacts linked with the same input should be connected in series.
8) All the N.O. contacts linked with the same input should be connected in parallel.
- THE INSERTION OF AN external, Independent DISCONNECTING SWITCH (not supplied) of suitable
capacity for the load Is envisaged for the control unit power supply.
accordance with the laws In force and In compliance with standards EN 12453 and EN 12445 regarding
