Maschinenfabrik Reinhausen GmbH 2020 21 4453918/14 EN ETOS® TD 3 IT security Observe the following recommendations for secure operation of the product. General ▪ Ensure that only authorized personnel have access to the device. ▪ Only use the device within an ESP (electronic security perimeter). Do not connect the device to the Internet in an unprotected state. Use mecha- nisms for vertical and horizontal network segmenting and security gate- ways (firewalls) at the transition points. ▪ Ensure that the device is only operated by trained personnel who are fa- miliar with IT security. Commissioning Observe the following recommendations for device commissioning: ▪ User IDs must be unique and assignable. Do not use a "Group account" function or the "Auto login" function. ▪ Activate the "Auto logout [►Section 9.2.2, Page 77]" function. ▪ Restrict the rights of the individual user groups as much as is feasible; this helps avoid errors during operations. A user with the "Operator" role, for example, should only perform operations and should not be able to change any device settings. ▪ Delete or disable the default "admin" user ID. This requires first creating a new user account with the "Administrator" role. You can then use it to delete or disable the default "admin" account. ▪ Deactivate service user access [►Section 9.2.3, Page 78]. ▪ Enable SSL/TLS encryption [►Section 9.2, Page 75]; access to the de- vice is then only possible using the SSL/TLS protocol. In addition to en- crypting communication, this protocol also checks the authenticity of the server. ▪ Use TLS version 1.2 or higher wherever possible. ▪ Integrate the device into a public key infrastructure. Create your own SSL certificates for this if necessary and then import them. ▪ Connect the device to a central log server by using the syslog interface [►Section 9.6, Page 85]. ▪ Only use the SNMP function if you can ensure that the communication is protected by external security equipment. Operation Observe the following recommendations during device operation: ▪ Change the password at regular intervals. ▪ Export the security log [►Section 9.36.1, Page 287] at regular intervals. ▪ Check the log files regularly for unauthorized system access and other se- curity-related events.

Maschinenfabrik Reinhausen GmbH 2020 46 4453918/14 EN ETOS® TD 5 Packaging, transport and storage 5.1 Packaging The products are sometimes supplied with sealed packaging and sometimes in a dry state, depending on requirements. Sealed packaging surrounds the packaged goods with plastic foil on all sides. Products that have also been dried are identified by a yellow label on the sealed packaging. In the dry state, delivery is also possible in a transport container. The information in the following sections should be applied as appropriate. 5.1.1 Suitability NOTICE Property damage due to incorrectly stacked crates! Stacking the crates incorrectly can lead to damage to the packaged goods. ►The outer marking on the packaging states if, for example, the on-load tap-changer or selector has been packed upright. Never stack these crates. ►General rule: Do not stack crates above a height of 1.5 m. ►For other crates: Only stack up to 2 equally sized crates on top of one an- other. The packaging is suitable to ensure undamaged and fully functional means of transportation in compliance with local transportation laws and regula- tions. The packaged goods are packed in a sturdy crate. This crate ensures that, when in the intended transportation position, the packaged goods are stabi- lized to prevent impermissible changes in position, and that none of the parts touch the loading surface of the means of transport or touch the ground after unloading. Sealed packaging surrounds the packaged goods with plastic foil on all sides. The packaged goods are protected from humidity using a desiccant. The plastic foil was bonded after the desiccant is added.

Maschinenfabrik Reinhausen GmbH 2020 47 4453918/14 EN ETOS® TD 5.1.2 Markings The packaging bears a signature with instructions for safe transport and cor- rect storage. The following symbols apply to the shipment of non-hazardous goods. Adherence to these symbols is mandatory. Protect against moisture Top Fragile Attach lifting gear here Center of mass Table 13: Shipping pictograms 5.2 Transportation, receipt and handling of shipments WARNING Danger of death or severe injury! Danger of death or serious injuries due to tipping or falling load. ►Only transport the crate when closed. ►Do not remove the securing material used in the crate during transport. ►If the product is delivered on a pallet, secure it sufficiently. ►Only trained and authorized persons may select the sling gear and se- cure the load. ►Do not walk under the suspended load. ►Use means of transport and lifting gear with a sufficient carrying capacity in accordance with the weight stated on the delivery slip. In addition to oscillation stress, jolts must also be expected during trans- portation. In order to prevent possible damage, avoid dropping, tipping, knocking over and colliding with the product. If a crate tips over, falls from a certain height (e.g. when slings tear) or is subject to an unbroken fall, damage must be expected regardless of the weight. Every delivered shipment must be checked for the following by the recipient before acceptance (acknowledgment of receipt): ▪ Completeness based on the delivery slip ▪ External damage of any type The checks must take place after unloading when the crate or transport con- tainer can be accessed from all sides.

Maschinenfabrik Reinhausen GmbH 2020 48 4453918/14 EN ETOS® TD Visible damage If external transport damage is found upon receipt of the shipment, proceed as follows: ▪ Immediately record the identified transport damage in the shipping docu- ments and have this countersigned by the carrier. ▪ In the event of severe damage, total loss or high damage costs, immedi- ately notify the manufacturer and the relevant insurance company. ▪ After identifying damage, do not modify the condition of the shipment fur- ther and retain the packaging material until an inspection decision has been made by the transport company or the insurance company. ▪ Record the details of the damage immediately on site together with the carrier involved. This is essential for any claim for damages. ▪ Photograph damage to packaging and packaged goods. This also applies to signs of corrosion on the packaged goods due to moisture inside the packaging (rain, snow, condensation). ▪ NOTICE! Damage to packaged goods due to damaged sealed packag- ing. If the product is delivered in sealed packaging, check the sealed packaging immediately. If the sealed packaging is damaged, do not under any circumstances install or commission the packaged goods. Either re- dry the dried packaged goods as per the operating instructions, or contact the manufacturer to agree on how to proceed. ▪ Identify the damaged parts. Hidden damage When damages are not determined until unpacking after receipt of the ship- ment (hidden damage), proceed as follows: ▪ Make the party responsible for the damage liable as soon as possible by telephone and in writing, and prepare a damage report. ▪ Observe the time periods applicable to such actions in the respective country. Inquire about these in good time. With hidden damage, it is very hard to make the transportation company (or other responsible party) liable. Any insurance claims for such damages can only be successful if relevant provisions are expressly included in the insur- ance terms and conditions. 5.3 Storage of shipments Packaged goods dried by Maschinenfabrik Reinhausen Upon receipt of the shipment, immediately remove the packaged goods dried by Maschinenfabrik Reinhausen from the sealed packaging and store air-tight in dry insulating fluid until used if the packaged goods were not sup- plied in insulating fluid. Non-dried packaged goods Non-dried packaged goods but with a functional sealed packaging can be stored outdoors when the following conditions are complied with.

Maschinenfabrik Reinhausen GmbH 2020 49 4453918/14 EN ETOS® TD When selecting and setting up the storage location, ensure the following: ▪ Protect stored goods against moisture (flooding, water from melting snow and ice), dirt, pests such as rats, mice, termites and so on, and against unauthorized access. ▪ Store the crates on timber beams and planks as a protection against ris- ing damp and for better ventilation. ▪ Ensure sufficient carrying capacity of the ground. ▪ Keep entrance paths free. ▪ Check stored goods at regular intervals. Also take appropriate action after storms, heavy rain or snow and so on. Protect the packaging foil from direct sunlight so that it does not disintegrate under the influence of UV rays, which would cause the packaging to lose its sealing function. If the product is installed more than 6 months after delivery, suitable mea- sures must be taken without delay. The following measures can be used: ▪ Correctly regenerate the drying agent and restore the sealed packaging. ▪ Unpack the packed goods and store in a suitable storage space (well ven- tilated, as dust-free as possible, humidity < 50% where possible). 5.4 Unpacking shipments and checking for transportation damages ▪ NOTICE! Transport the packaged crate to the place where installation will take place. Do not open the sealed packaging until just before installation.

If you activate unsolicited messages, the device sends a message via the control system every time a value is changed. 9.7.6.5 Repetition of unsolicited messages You can use this parameter to set how often the device is to send an unso- licited message until it receives a response from the DNP3 master. 9.7.6.6 Repeat unsolicited messages indefinitely You can use this parameter to set the device to send an indefinite number of unsolicited messages until it receives a response from the DNP3 master. 9.7.6.7 Timeout You can use this parameter to set the timeout for unsolicited messages. 9.7.6.8 Timeout for response confirmation You can use this parameter to set the timeout for response confirmation for unsolicited messages. 9.7.6.9 User ID code You can use this parameter to set the user ID code.

100 4453918/14 EN ETOS® TD Reference time You can use this parameter to set which time is to be transmitted by the con- trol system. The device uses this information for time synchronization [►Section 9.5, Page 83]. You can select the following options: Option Description Local The control system transmits the local time. Note: If you use this option, you must deactivate the au- tomatic changeover between daylight saving time and standard time [►Page 84]. Otherwise the device will use an incorrect time. UTC The control system transmits the time as UTC. The de- vice calculates the local time from UTC and the set time zone [►Page 84]. Table 29: Reference time 9.7.7 Configuring GOOSE (optional) You can use the optional GOOSE function to send GOOSE messages (GOOSE publisher) or receive GOOSE messages (GOOSE subscriber) via the IEC 61850 control system protocol with the device. The configuration of GOOSE is described in the following sections. 9.7.7.1 Configuring GOOSE publisher If you configure the device as a GOOSE publisher, you can send all data points which the device provides via MMS as GOOSE messages. To do this, you have to configure the data points using DataSets in an SCD/CID file. SCD/CID file requirements ▪ The GOOSE control block (GSEControl) and the associated DataSet can only be created in LLN0. ▪ GSE elements for the configuration of the GOOSE message can be cre- ated under ConnectedAP. ▪ The maximum number of data points per GOOSE message is defined in Private Element type="MR-MAX-GOOSE-PUBLISH-FCDA". You cannot adjust this value. ▪ The maximum number of usable GSEControl elements is defined in TEM- PLATE.icd under Services GOOSE. You cannot adjust this value. ▪ The shortest repeat time is defined in Private Element type="MR- MINTIME-GOOSE". You cannot adjust this value.
