3.3) Electrical connections
!
To safeguard the operator and avoid damaging the components, make sure that the control unit is switched off while
you are wiring or plugging in the various cards.
• Power the control unit using a 3 x 1.5 mm
earth plate near the unit.
• Use wires with a minimum cross-section of 0.25 mm
• Use shielded wires if the length exceeds 30m and only connect the earth braid to the control unit side.
• Do not make connections to cables in buried boxes even if they are completely watertight.
• If the inputs of the Normally Closed (NC) contacts are not used, they should be jumped with the "24V common" terminal except for the
photocell inputs if the phototest function is enabled. For further information please see the paragraph 3.5 "Notes about connections" in the
part " Phototest ".
• If there is more than one (NC) contact on the same input, they must be connected in SERIES.
• If the inputs of the Normally Open (NA) contacts are not used they should be left free.
• If there is more than one (NA) contact on the same input, they must be connected in PARALLEL.
• The contacts must be mechanical and potential-free; no stage connections are allowed, such as those defined as "PNP", "NPN", "Open
Collector", etc.
Carry out the necessary connections, following the diagram in Fig. 4 and the following description of the connections.
Remember that there are specific standards that must be complied with both as regards the safety of the electrical systems and as regards
automatic gates.
