Supply voltage
When the supply voltage is connected at the "Power" input, all LEDs flash briefly for a moment.
The POWER LED lights up permanently in green as soon as voltage is present.
Check whether the rated voltage of the power supply corresponds to the values in the section
"Technical specifications".
CAUTION
Safety extra low voltage
The equipment is designed for operation with Safety Extra-Low Voltage (SELV) by a Limited
Power Source (LPS). (This does not apply to 100 V...240 V devices.)
This means that only SELV / LPS complying with IEC 60950‑1 / EN 60950‑1 / VDE 0805‑1
must be connected to the power supply terminals, or the power supply unit for the equipment
power supply must comply with NEC Class 2, as described by the National Electrical Code (r)
(ANSI / NFPA 70).
