1 GeneralBU 0135 en-4118 151.4 Safety, installation and operating instructionsBefore working on or with the device, please read the following safety instructions extremely carefully.Please pay attention to all other information from the device manual.Non-compliance can result in serious or fatal injuries and damage to the device or its surroundings.These safety instructions must be kept in a safe place!1. GeneralDo not use defective devices or devices with defective or damaged housings or missing covers (e.g.blind plugs for cable glands). Otherwise there is a risk of serious or fatal injuries caused by electricshock or bursting electrical components such as powerful electrolytic capacitors.Unauthorised removal of covers, improper use, incorrect installation or operation causes a risk ofserious personal injury or material damage.During operation and depending on the protection class of the devices, there may be live, bare,moving or rotating parts or hot surfaces.The device operates with a dangerous voltage. Dangerous voltage may be present at the supply lines,contact strips and PCBs of all connecting terminals (e.g. mains input, motor connection), even if thedevice is not working or the motor is not rotating (e.g. caused by electronic disabling, jamming of thedrive or a short circuit at the output terminals).The device is not equipped with a mains switch and is therefore always live when connected to thepower supply. Voltages may therefore be connected to a connected motor at standstill.Even if the drive unit has been disconnected from the mains, a connected motor may rotate andpossibly generate a dangerous voltage.If you come into contact with dangerous voltage such as this, there is a risk of an electric shock, whichcan lead to serious or fatal injuries.The device and any power plug connectors must not be disconnected while a voltage is applied to thedevice. Failure to comply with this may cause arcing, which in addition to the risk of injury, also resultsin a risk of damage or destruction of the device.The fact that the status LED or other indicators are not illuminated does not indicate that the devicehas been disconnected from the mains and is without voltage.The heat sink and all other metal components can heat up to temperatures above 70 °C.Touching these parts can result in local burns to the body parts concerned (cooling times andclearance from neighbouring components must be complied with).All work on the device, e.g. transportation, installation, commissioning and maintenance work must becarried out by qualified experts (observe IEC 364 or CENELEC HD 384 or DIN VDE 0100 andIEC 664 or DIN VDE 0110 and national accident prevention regulations). In particular, the general andregional installation and safety regulations for work on high voltage systems (e.g. VDE) must becomplied with as must the regulations concerning correct use of tools and the use of personalprotection equipment.During all work on the device, take care that no foreign bodies, loose parts, moisture or dust enter orremain in the device (risk of short circuit, fire and corrosion).Further information can be found in this documentation.
