Only use the device in the following environments:- Environments not subject to explosion hazards- Potentially explosive atmosphere, Zone 22 (according to ATEX 94/9/EC) Potentially explosive atmosphere, Zone 22:The ground resistance of accessible metal parts must be less than 10 9 ohms. When used in potentially explosive atmosphere, Zone 22, the environment hasto be designed to avoid any bunch discharge. Prevent the device from being subjected to hazardous knocks. Only operate the device in potentially explosive atmospheres if it is correctlymounted. Switch off the device before removing the plug connections.WARNINGLive parts in the deviceWhen the device is opened, there is a risk of electric shock if live parts are touched. The device must not be opened.WARNINGPotential equalization currentsLarge equalization currents between the protective ground systems of different de-vices may cause operational malfunctions due to signal interference and may evencause fires. If necessary, a potential equalization conductor should be installed parallel to thecable. This should have a cross-section that is a multiple of the cable shield.CAUTIONElectrostatic dischargeElectrostatic discharge may damage or destroy electronic components. Avoid contact with components (such as connector pins) that are susceptible toelectrostatic discharge. Discharge (by touching a grounded metal object) any static charge accumulatedin your body before touching the device.
