Project Planning Manual | Rexroth MKE Synchronous Motors Electric Drivesand Controls| Bosch Rexroth AG 17/131Safety Instructions for Electric Drives and ControlsWARNINGWARNINGHigh electrical voltage! Danger to life, risk of injury by electric shock orserious injury!●●●●Only qualified persons are allowed to operate, maintain and/or repair theelectric components of the drive and control system.Follow the general installation and safety regulations when working onpower installations.Before switching on, the equipment grounding conductor must have beenpermanently connected to all electric components in accordance with theconnection diagram.Even for brief measurements or tests, operation is only allowed if theequipment grounding conductor has been permanently connected to thepoints of the components provided for this purpose.● Before accessing electrical parts with voltage potentials higher than 50 V,you must disconnect electric components from the mains or from the powersupply unit. Secure the electric component from reconnection.●●●●●●With electric components, observe the following aspects:Always wait 30 minutes after switching off power to allow live capacitorsto discharge before accessing an electric component. Measure the electricalvoltage of live parts before beginning to work to make sure that theequipment is safe to touch.Install the covers and guards provided for this purpose before switchingon.Never touch electrical connection points of the components while poweris turned on.Do not remove or plug in connectors when the component has been powered.As a basic principle, residual-current-operated circuit-breakers cannot beused for electric drives to prevent direct contact.Secure built-in devices from penetrating foreign objects and water, as wellas from direct contact, by providing an external housing, for example acontrol cabinet.High housing voltage and high leakage current! Danger to life, risk ofinjury by electric shock!●●●Before switching on and before commissioning, ground or connect thecomponents of the drive and control system to the equipment groundingconductor at the grounding points.Connect the equipment grounding conductor of the components of thedrive and control system permanently to the main power supply at alltimes. The leakage current is greater than 3.5 mA.Establish an equipment grounding connection with a copper wire of across section of at least 10 mm 2 (8 AWG) or additionally run a secondequipment grounding conductor of the same cross section as the originalequipment grounding conductor.3.3.2 Protective Extra-Low Voltage as Protection Against Electric ShockProtective extra-low voltage is used to allow connecting devices with basic insulationto extra-low voltage circuits.All connections and terminals with voltages between 5 and 50 volts at the componentsof the Bosch Rexroth drive and control system are PELV ("ProtectiveExtra-Low Voltage") systems. It is allowed to connect devices equipped
