ELECTRIC WIRING EXAMPLE
RECCOMENDATIONS FOR A SAFE WIRING IN EXTERNAL GENERAL TYPE ENVIRONMENTS
1. Verify the presence of an isolating switch upstream the installation, with an open contact clearance of 3mm or higher.
2. Before operating any wiring, switch OFF the isolating switch (the "0" symbol should be visible). Verify that any source of
power is disconnected before wiring. Particularly, the control unit should never be powered during the wiring phase, nor
when connecting devices or expansions to it.
3. Wire the components of the system using the following types of cables:
- devices powered @230Vac (control unit, operator, flashing light): use cables having section 1.5mm
2
/ 2.5mm
2
for length up
to 19m / 31m,
- devices SELV powered by the control unit (photocells, command buttons, electromechanical keys, etc.): use cables having
section 0.5mm
2
/ 0.75mm
2
for length up to 50m / 100m.
4. Wire the earth connection in compliance with the standard prescriptions.
