Title: 563-Beckhoff-Endeblokk KL9010.pdf
a protection class of at least IP54 in accordance with EN 60529! The environmental conditions during use are thereby to be taken into account! If the temperatures during rated operation are higher than 70°C at the feed-in points of cables, lines or pipes, or higher than 80°C at the wire branching points, then cables must be selected whose temperature data correspond to the actual measured temperature values!Observe the permissible ambient temperature range of 0 - 55°C for the use of Beckhoff fieldbus components in potentially explosive areas!Observe the permissible ambient temperature range of 0 - 55°C for the use of Beckhoff fieldbus components in potentially explosive areas!Measures must be taken to protect against the rated operating voltage beingexceeded by more than 40% due to short-term interference voltages! • The individual terminals may only be unplugged or removed from the BusTerminal system if the supply voltage has been switched off or if a non-explosive atmosphere is ensured!
