TECHNICAL NOTE
INSTALLATION:
•
CAUTION: The product may only be connected and installed by a qualified electrician. All applicable regulations, legislation,
and building codes must be observed. Incorrect installation of the product can cause irreparable damage to the product
and the connected LEDs.
•
Maintenance must be performed only by a qualified electrician in compliance with current regulations.
•
The product must be installed inside a switchgear/controlgear cabinet and/or junction box protection against overvoltage.
•
The product must be installed in a vertical or horizontal position with the label/top cover facing upwards or vertically.
Other positions are not permitted. The bottom position is not permitted (label/top cover facing down).
•
Keep separated 230Vac (LV) circuits and not SELV circuit from safety extra low voltage (SELV) circuit and from any
connection with this product. It is absolutely forbitten to connect, for any reason whatsoever, directly or indirectly, the
230Vac mains voltage to the product (terminal block of BUS included).
•
The product must be dissipated correctly.
•
The use of the product in harsh environments could limit the output power.
POWER
SUPPLY
•
Only use SELV power supplies with limited current for device power supply, short circuit protection and the power must
be dimensioned correctly.
In the case of power supplies equipped with ground terminals, it is mandatory to connect ALL protective ground points
(PE= Protection Earth) to a properly and certified protection earth.
•
The connection cables between the very low voltage power source and the product must be properly dimensioned and
must be insulated from any wiring or part at non-SELV voltage. Use double insulated cables.
•
Dimension the power of the power supply in relation to absorption of device. In case the power supply is oversized
compared to the maximum absorbed current, insert a protection against over-current between the power supply and the
device.
COMMAND
•
The length of the cables connecting between the local commands (N.O. Push button, 0-10V, 1-10V, Potentiometer or
other) and the product must be less than 10m. The cables must be properly dimensioned and must be insulated from any
non-SELV wiring or voltage. It is recommended to use double insulated cables, if deemed appropriate also shielded.
•
The length and type of cables connecting to the bus (DMX, Modbus, DALI, Ethernet or other) must comply with the
specifications of the respective protocols and the regulations in force. They must be insulated from any non-SELV wiring
or voltage parts. It is recommended to use double insulated cables.
•
ALL device and control signal connected to the local command “N.O. Push button”, they must not supply any type of
voltage.
•
ALL device and control signal connect at the BUS (DMX512, Modbus, DALI, Ethernet or other) and to the local command
(N.O. Push button or other) must be SELV type (the device connected must be SELV or supply SELV signal).
