Important notes on using devices of the SIMIT UNIT product family
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 Information
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 Safety Extra-Low Voltages (SELV) with Limited Power Source (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 ® (ANSI / NFPA 70).
There is an additional requirement if devices are operated with a redundant power supply:
If the device is connected to a redundant power supply (two separate power supplies), both
must meet these requirements.
WARNING
Opening the device
DO NOT OPEN THE DEVICE WHEN ENERGIZED.
General notices regarding use in hazardous areas
WARNING
Risk of explosion when connecting or disconnecting the device
DANGER OF EXPLOSION
DO NOT CONNECT OR DISCONNECT EQUIPMENT WHEN A FLAMMABLE OR
COMBUSTIBLE ATMOSPHERE IS PRESENT.

WARNING
Replacing components
DANGER OF EXPLOSION
REPLACEMENT OF COMPONENTS MAY IMPAIR SUITABILITY FOR CLASS I, DIVISION
2 OR ZONE 2.
WARNING
Requirements for the control cabinet
When used in hazardous environments corresponding to Class I, Division 2 or Class I, Zone
2, the device must be installed in a cabinet or a suitable enclosure.
Notice for use in hazardous areas according to ATEX
WARNING
Requirements for the control cabinet
To comply with EU Directive 94/9 (ATEX95), this enclosure must meet the requirements of
at least IP54 in compliance with EN 60529.
WARNING
Suitable cables for temperatures in excess of 70 °C
If the cable or conduit entry point exceeds 70 °C or the branching point of conductors exceeds
80 °C, special precautions must be taken. If the equipment is operated at ambient
temperatures of 50 °C to 70 °C, only use cables with a permitted 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.
