Turn off and lock out all power supplying this device before working on this device. The measuring input fulfils reinforced insulation according to DIN EN 61010-1 for overvoltage category II and pollution degree 2. Connected voltages may not exceed 300 V AC/DC to earth. To use the equipment flawless and safe, transport and store properly, install and start professionally and operate as directed. Only let persons work with the equipment who are familiar with installation, start and use and who have appropriate qualification corresponding to their function. They must observe the contents of the instructions manual, the information which are written on the equipment and the relevant security instructions for the setting up and the use of electrical units. The equipment is built according to DIN / EN and checked and leave the plant according to security in perfect condition. If, in any case the information in the instructions manual is not sufficient, please contact our company or the responsible representative. Instead of the industrial norms and regulations written in this instruction manual valid for Europe, you must observe out of their geographical scope the valid and relevant regulations of the corresponding country. Observe the maximum temperature permissible when installing in switching cabinet. Make sure sufficient space to other equipment or heat sources. If the cooling becomes more difficult e.g. through close proximity of apparatus with elevated surface temperature or hindrance of the cooling air, the tolerable environmental temperature is diminishing. Attention! Universal power supply The device has a universal power supply, that is suitable for DC- and AC voltages. Before connecting the device to supply-voltage make sure that the connected voltage corresponds with the voltage on the lateral type on the device.
