3 Safety instructions3.4 Device-specific hazardsXP-503 04/2020 MN048014 EN Eaton.com 173.4 Device-specific hazardsDangerExplosion hazardDeath, serious injury, and property damage may occur if the device is being used ina potentially explosive (classified) location and, during operation, an electrical plugconnection is disconnected or the device is exposed to dangerous impacts or othertypes of dangerous mechanical shock.Use the device in the following environments only:- Non-hazardous (non-explosive) area- Hazardous (explosive) area, zone 22 (as defined in the ATEX Directive),only device type XP-503-…-A10-A01-… The ground resistance of accessible metal parts must be less than 109 Ohms. Make sure that the device is not exposed to dangerous impacts and other typesof dangerous mechanical shock. De-energize the device before disconnecting plug connections. Clean only with a clean soft antistatic damp cloth When used in a potentially explosive atmosphere, zone 22The XP-503-…-A10-A01-… are designed for installation in the front of enclosures inprotection type "tc" (alternatively "ta" or "tb"). This installation must be tested andcertified separately. The maximum surface temperature at the outer surface is set to70°C at the maximum ambient temperature of 50°C. The environment has to bedesigned to avoid any bunch discharge. For safe installation, comply with thespecification to holding brackets and tightening torque in the Instruction Leaflet.WARNINGLive parts inside the deviceWhen the device is open, there will be an electric shock hazard if live parts aretouched. Do not open the device if it is not de-energized.WARNINGStray currentsLarge transient currents between the protective circuits of different devices mayresult in fire or in malfunctions due to signal interference. If necessary, route an equipotential bonding conductor, with a cross-sectionalarea that is several times larger than that of the cable screen, parallel to thecable.
