SIPROTEC 5, Merging Unit 6MU85, Manual 5 C53000-G5040-C074-1, Edition 01.2020 Preface NOTICE NOTICE means that property damage can result if the measures specified are not taken. � Comply with all instructions, in order to avoid property damage. i NOTE Important information about the product, product handling or a certain section of the documentation which must be given attention. Qualified Electrical Engineering Personnel Only qualified electrical engineering personnel may commission and operate the equipment (module, device) described in this document. Qualified electrical engineering personnel in the sense of this manual are people who can demonstrate technical qualifications as electrical technicians. These persons may commission, isolate, ground and label devices, systems and circuits according to the standards of safety engineering. Proper Use The equipment (device, module) may be used only for such applications as set out in the catalogs and the technical description, and only in combination with third-party equipment recommended and approved by Siemens. Problem-free and safe operation of the product depends on the following: � Proper transport � Proper storage, setup and installation � Proper operation and maintenance When electrical equipment is operated, hazardous voltages are inevitably present in certain parts. If proper action is not taken, death, severe injury or property damage can result: � The equipment must be grounded at the grounding terminal before any connections are made. � All circuit components connected to the power supply may be subject to dangerous voltage. � Hazardous voltages may be present in equipment even after the supply voltage has been disconnected (capacitors can still be charged). � Operation of equipment with exposed current-transformer circuits is prohibited. Before disconnecting the equipment, ensure that the current-transformer circuits are short-circuited. � The limiting values stated in the document must not be exceeded. This must also be considered during testing and commissioning.

CAUTION Risk of burns due to high temperatures of the SFP pluggable transceivers Noncompliance with the safety notes may result in medium or light injuries. � The SFP pluggable transceivers can be disconnected and plugged in while in operation. Siemens recommends switching off the device. � Allow the SFP pluggable transceiver to cool as much as possible. Remove the connecting cables or the dust protection cap that was plugged on in the delivery state from the SFP pluggable transceiver. In order to release the interlocking, open the bracket on the SFP pluggable transceiver. Pull on the bracket in order to pull the SFP pluggable transceiver out of the slot. The removal must be possible with free movement and without great exertion of force. Provide the SFP pluggable transceiver with the dust protection cap so that the optics are protected from contamination. Mounting SFP Pluggable Transceivers Check whether the bracket on the SFP pluggable transceiver is closed. The bracket must be closed. Insert the pluggable transceiver into the slot until it audibly locks in place. The SFP is securely fixed in the slot. i NOTE Check for secure positioning of the transceiver in the slot and whether it is locked in place in order to avoid unintentional removal by pulling on the connection line. 12.1.6 Design Data Masses Type of construction Flush-mounting device Device Size Weight of the Modular Devices 1/3 1/2 2/3 4.4 kg 7.2 kg 9.9 kg 5/6 12.7 kg 1/1 15.5 kg SIPROTEC 5, Merging Unit 6MU85, Manual 797 C53000-G5040-C074-1, Edition 01.2020 Technical Data 12.1 General Device Data Surface-mounted device with integrated on-site operation panel Surface-mounted device with detached on-site operation panel Device Size Weight of the Modular Devices 7.4 kg 11.7 kg 15.9 kg 4.7 kg 7.8 kg 10.8 kg 20.2 kg 13.9 kg Size Detached on-site operation panel 1/3 Detached on-site operation panel 1/6 Weight 1.9 kg 1.1 kg Type of construction Flush-mounting device Bracket for non-modular surfacemounted variant Device Size Weight of the Non-Modular Devices 7xx81, 7xx82 1/3 3.6 kg 1.9 kg 24.5 kg 17.0 kg Dimensions of the Base and 1/3 Modules Type of Construction (Maximum Dimensions) Width over all x Height over all x Depth (incl.
