*Color rotation speed is selectable from 4 predefined levels.
The selected speed is visualized with a white strobo output:
- 10 flash/s for the rotation of seconds
- 5 flash/s for the rotation of 30 seconds
- 2 flash/s for the rotation of minutes
- 1 flash/s for the rotation of 30 minutes
Technical otes
Installation:
• Installation and maintenance must be performed only by qualified personnel in compliance with current regulations.
• The product must be installed inside an electrical panel protected against overvoltages.
• The product must be installed in a vertical or horizontal position with the cover / label upwards or vertically; Other positions are not permitted.
It is not permitted to bottom-up position (with the cover / label updown).
• Keep separated the circuits at 230V (LV) and the circuits not SELV from circuits to low voltage (SELV) and from any connection with this
product. It is absolutely forbidden to connect, for any reason whatsoever, directly or indirectly, the 230V mains voltage to the bus or to other
parts of the circuit.
Power Supply:
• For the power supply use only a SELV power supplies with limited current, short circuit protection and the power must be dimensioned
correctly.
In case of using power supply with ground terminals, all points of the protective earth (PE = Protection Earth) must be connected to a valid and
certified protection earth.
• The connection cables between the power source "low voltage" and the product must be dimensioned correctly and they should be isolated
from every wiring or parts at voltage not SELV. Use double insulated cables.
• Dimension the power supply for the load connected to the device. If the power supply is oversized compared with the maximum absorbed
current, insert a protection against over-current between the power supply and the device.
• For the constant current output, the voltage of LED module (Vf) must be less of 5V at the voltage of power supply.
Command:
• The length of the connection cables between the local commands (N.O. Push button or other) and the product must be less than 10m; the
cables must be dimensioned correctly and they should be isolated from every wiring or parts at voltage not SELV. Use double insulated
shielded and twisted cables.
• All the product and the control signal connect at the local command (N.O. Push Button or other) must be SELV (the devices connected must
be SELV or supply a SELV signal)
Outputs:
• The length of the connection cables between the product and the LED module must be less than 10m; the cables must be dimensioned
correctly and they should be isolated from every wiring or parts at voltage not SELV. Is preferable to use shielded and twisted cables.
