Page 7: Preparation Of The Measurement Application
4. Preparation of the measurement application 4.1 Connecting to the measurement device 4.1.1 Connection via LAN interface Before devices can be connected to an existing Ethernet network, you have to ensure that they will not disturb the normal network service. The rule is: None of the devices to connect is allowed to have the same IPv4/6 address than another device already installed This also applies if the network only consists of a PC and the measuring device. - Page 8 Network settings (Communication | Ethernet) The following settings have to be arranged with the network administrator: Must be unique, i.e. may be assigned in the network only once • IPv4/6: IP address Defines how many devices are directly addressable in the IPv4 network. This •...
- Page 9 Time synchronization via NTP protocol For the time synchronization of devices via Ethernet NTP (Network Time Protocol) is the standard. Corresponding time servers are used in computer networks, but are also available for free via Internet. Using NTP it's possible to hold all devices on a common time base. Two different NTP servers may be defined.

Page 15: Security System
4.3 Security system There are several security mechanisms implemented in the device which can be activated to provide a comprehensive access protection to all device data. The role-based access control (RBAC) system allows restricting the access to measured data, configuration settings and service functions to the rights granted to the present user. - Page 16 Adding users / API keys In addition to the 2 predefined users a maximum of 6 users or API keys may be created. To do so, use “Add user / API key” and select the type of user to be created. Users: During password definition the requirements for a secure password are checked and the result is displayed.
- Page 17 Once the API key is created it can be displayed using “Show API key” When the application wants to communicate via REST interface with the device, it has to provide the API key and the session token via the cookie field in the request header, e.g.: Further information is provided in the document “http interface SINEAX PQx000”...

Page 19: Whitelisting Clients
Before HTTPS communication can be used a root certificate needs to be installed. The user can either use a Camille Bauer certificate (default setting) or its own customer certificate. This may be changed when defining the Settings of the Security system. -
Page 20: Audit Log (Syslog)
The imported certificate is valid for all devices of the PQ, AM, DM and CU series. Agree to install the certificate if the below security warning appears: Customer certificate You may also use a customer server certificate with a private key, but for that you first need to change the Settings of the Security system in the item Web Security. - Page 21 Example of a security log: The severity of each message is shown in a color code, which may also serve as filter criteria. Each entry into this list may, if activated, also be transferred to a central log-server using the SYSLOG protocol for security auditing.

Page 22: Pq Monitoring
4.4 PQ monitoring Power quality monitoring provides both a statistical evaluation, allowing an assessment of compliance with standards (e.g. EN 50160) or supply contracts, as well as records of events in the grid (e.g. power voltage dips). This facilitates the analysis of causes and effects. Conformity reports may also be created directly via the website of the device. -
Page 23: Pq Statistic
Mains signalling voltage The device monitors mains signalling voltages, which are transmitted in the supply system for control purposes, and records them as events (8.1.3). Typically, these are ripple control signals. The user can define the frequency of the signalling voltage, the threshold and hysteresis (related to the nominal voltage) as well as the recording duration in multiples of the measurement interval of 10/12 cycles. -

Page 25: Safety Instructions
5. Safety instructions Death, serious injury or fire hazard could result from improper connection of this instrument. Before connecting the PQ5000MOBCLM and the current modules you have to read and understand this manual. General Connection of this instrument must be performed in compliance with all applicable national regulations on electricity and any additional safety requirements applicable to your installation. - Page 26 When connecting If measurements are made which involve a risk of contact, a second person should be present on-site. This is typically the case during the connection of the current and voltage measurement inputs. De-energize the electrical circuit to be monitored before connecting the test leads and current sensors.

Page 28: Current Connection Current Link
6.3 Current connection Current Link The Current Link supports the current measurement of up to 9 feeders with up to 36 current channels. It consists of Current Modules, which are arranged in a ring structure and monitor 3 or 4 channel feeders. A typical connection of a PN-Moduls is shown below: Rogowski coils The Rogowski coils of the current modules are different in color and also marked: Brown –... - Page 29 The individual current modules in the ring are connected using SMA connection cables. The SMA connection cables must not be kinked during assembly, as the conductors could be damaged. The bending radius should be not smaller than 50mm. The fastening of the SMA cables to the corresponding connectors should be done with a torque wrench with a maximum torque of 1 Nm.

The junction box of a current module must not be mounted on bare conductors, nor must connecting cables be routed over bare live conductors. If there are bare connections or busbars in the immediate vicinity, the junction box and connecting cables must be secured in such a way that their metal parts cannot touch live, bare parts in the event that the fixing of the junction box or a connecting cable becomes detached unexpectedly. -

6.5 GPS time synchronization The optional GPS connection module serves for connecting a GPS receiver as a very accurate time synchronization source for the measurement device. Time synchronization via NTP or GPS is an elementary requirement for class A power quality measuring devices. -
Page 32: Power Supply
Connecting the GPS receiver Never connect the RJ45 socket of the connecting cable directly to a network device such as a router or switch. These devices could be damaged. The GPS receiver is plugged directly into the GPS connection module. The connection cable has a length of 5 m. -

Page 35: Measurement Data Reset
7.3 Measurement data reset The device can store data of up to 20 measurement locations. If measurement locations are replaced, i.e. new configurations are loaded into the device, data belonging to the old configurationen can no longer be evaluated correctly and should therefore be deleted. However, data cannot be deleted for individual configurations, only as a whole. -
Page 36: Start / Stop Data Recording
7.4 Start / stop data recording The data recording can be started or stopped directly at the device or via the device website. There is a delay when starting and stopping data recording until this state change completes. During this delay the local LED associated to the RECORD button flashes and a corresponding status window is displayed via device website. -
Page 37: Evaluation Of Recorded Data
8. Evaluation of recorded data For the evaluation of recorded data, you first have to activate the configuration used during data recording. Only data recorded with the active configuration will then be visible and can be assessed. ATTENTION: If the configuration used during data recording has been changed or is no longer available, an evaluation of the data may no longer be possible. -
Page 38: Periodical Data
Data export as CSV file In some data visualizations an export as CSV file (Comma Separated Value) can be made. For courses of measurements (e.g. meter contents) the time range of the data to export can be selected. For event lists the last 250 events are stored. The created CSV file can be imported as a text file to Excel, with comma as a separator. -
