Page 20: Important Notes On Using The Device
Installation 4.1 Important notes on using the device Important notes on using the device Read the safety notices Note the following safety notices. These relate to the entire working life of the device. WARNING If a device is operated in an ambient temperature of more than 55 °C, the temperature of the device enclosure may be higher than 70 °C. - Page 21 Installation 4.1 Important notes on using the device WARNING The device is intended for indoor use only. WARNING The device may only be operated in an environment of contamination class 1 or 2 (see EN/IEC 60664-1, GB/T 16935.1). WARNING 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.
- Page 22 Installation 4.1 Important notes on using the device WARNING Unprotected cable ends There is a risk of explosion due to unprotected cable ends in hazardous areas. • Protect unused cable ends according to IEC/EN 60079-14. WARNING Improper installation of shielded cables There is a risk of explosion due to equalizing currents between the hazardous area and the non- hazardous area.
- Page 23 Installation 4.1 Important notes on using the device WARNING Transient overvoltages Take measures to prevent transient overvoltages of more than 40% of the rated voltage (or more than 119 V). This is the case if you only operate devices with SELV (safety extra-low voltage).
