WARNING
Incorrect power supply
The power supply unit to supply the device must comply with NEC Class 2 (voltage range
18 - 32 V, current requirement 350 mA).
Do not operate the device with an AC voltage.
Never operate the device with DC voltages higher than 32 VDC.
WARNING
The equipment is designed for operation with Safety Extra-Low Voltage (SELV) by a
Limited Power Source (LPS).
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. The power supply unit for the equipment
power supply must comply with NEC Class 2, as described by the National Electrical Code
