Safety notices on the use of the device
The following safety notices must be adhered to when setting up and operating the device and
during all associated work such as installation, connecting up, replacing devices or opening
the device.
General notices
WARNING
Safety extra low voltage
The SCALANCE X204RNA is designed for operation with Safety Extra-Low Voltage (SELV)
by a Limited Power Source (LPS). (This does not apply to the SCALANCE X204RNA EEC.)
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
(r) (ANSI / NFPA 70).
If the equipment is connected to a redundant power supply (two separate power supplies),
both must meet these requirements.
WARNING
Maximum current
The maximum current via the terminals is 10 A. You should therefore include a fuse that trips
at a current higher than 10 A. The fuse must meet the following requirements:
● Suitable for 300 VDC / 250 VAC / max. 10 A
● Breaking current at least 10 kA
● UL/CSA listed (UL 248-1 / CSA 22.2 No. 248.1)
As an alternative, the following requirements:
● Breaking current at least 10 kA
● Approved in compliance with IEC 60127-1 / EN 60127-1
● Breaking characteristics: B or C for a circuit breaker or slow-blow fuse
