2.2) Electrical connections

To safeguard the operator and avoid damaging the
!
components while you are wiring or plugging in the
various cards: under no circumstances may the unit be
electrically powered.
• Power the unit using a 3 x 1,5mm
between the unit and the earth connection exceed 30m, install
an earth plate near the unit.
• Use wires with a minimum cross-section of 0.25mm
low voltage safety circuits.
• 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.

Description
= Mains power Line
= Output for connecting flashing light to mains voltage (Max. 40W)
= Clean contact output for courtesy light connection ( Max. 5A)
= 24Vac output to 24Vac +/- 25% services (Max. 150mA)
= Common for all inputs
= Phototest output ("TX" power supply to photocells) Max. 50mA
= Input with "Stop" function (Stop and short reverse run)
= Input for safety devices
= Input for the radio receiver aerial
• 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 "Phototest" paragraph.
• 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.
