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 work relating to it such as installation, connecting up, replacing devices or
opening the device.
General notes
WARNING
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. 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).
There is an additional requirement if devices are operated with a redundant power supply:
If the equipment is connected to a redundant power supply (two separate power supplies),
both must meet these requirements.
WARNING
Opening the device
DO NOT OPEN WHEN ENERGIZED.

ambient in excess of 50 °C, only use cables with admitted maximum operating temperature
of at least 80 °C.
WARNING
Protection against transient voltage surges
Provisions shall be made to prevent the rated voltage from being exceeded by transient
voltage surges of more than 40%. This criterion is fulfilled, if supplies are derived from
SELV (Safety Extra-Low Voltage) only.
Information on use in hazardous areas according to UL-HazLoc
WARNING
EXPLOSION HAZARD
DO NOT DISCONNECT WHILE CIRCUIT IS LIVE UNLESS AREA IS KNOWN TO BE
