2.2 Type of electrical wires
According to the installations , to the type and the quantity of the cables, the wires can be different, in the table is shown
the necessary cables for a standard installation.
The installation cables should be conformed to the IEC 60335 norm.
Power supply cable
Cable 3x1,5 mm

Motor cable (if it is not required)
Cable 4 x 1,5 mm
2
Lamp cable
Cable 2x1,5 mm

2.3 STANDARD INSTALLATION
2.4 Notes on connections
To guarantee operator safety and to prevent damaging the components, never make connections or insert wireless recei-
ver boards while the control unit is powered.
•
Power the control unit through a 3 x 1.5 mm
2
cable. If the distance between the control unit and the ground sy stem
connection is more than 30 m, a ground plate must be installed in proximity to the control unit.
•
If the motors do not have a cable, use the 4 x 1.5 mm
2
cable (open + close + ground).
•
In connecting the part with an extremely low safety voltage, use cables with a minimum section of 0.5 or 0.75 mm
2
.
•
Use shielded cables if the length exceeds 30m and connecting the ground braid only from the side of the control unit
•
Do not connect the cables in underground cases even if they are water-tight.
•
If they are not used, the inputs to the Normally Closed (NC) contacts must be jumpered to the “common”.
•
If the same input has more than one contact (NC), they are placed in series.
•
If they are not used, the inputs to the Normally Open (NO) contacts are left loose.
•
If the same input has more than one contact (NO), they are to be placed in series.
•
The contacts must be mechanical and free of any potential.
•
Remember that systems for automatic gates and doors must be installed by highly qualified technicians only and in full
compliance with current law.
It is important to make an important risk analysis of the “ MACHINE” and of the customers requirements in order to decide
how many products should be installed.
All NOLOGO photocells dispose of a synchronisation system which permit to avoid any interference between two couples
of photocells (look the photocell’s instructions for details)
In the diagram , photocells
“FOTO A”
in opening they have no effect, while it provoque a complete inversion during
closing.
“FOTO A2”
is the serial connection of
“FOTO A”
or
“ALT, FOTO B”
is the photocell working by closing and
opening.
