  • Page 13: Voltage Connection Base Unit

    5.4 Voltage connection base unit The voltage measurement inputs L1, L2 and L3 must originate at circuit breakers or fuses rated 5 Amps or less. This does not apply to the neutral connector. You have to provide a method for manually removing power from the device, such as a clearly labeled circuit breaker or a fused disconnect switch in accordance with IEC 60947-2 or IEC 60947-3.

  • Page 14: Current Connection Base Unit

    5.5 Current connection base unit Only for device versions with current measurement in the base unit PQ5000CL-001 / -101 No fuse may be connected upstream of the current measurement inputs! When using current transformers their secondary connectors must be short-circuited during installation and before removing the device.

  • Page 15: Current Link Current Connections

    5.6 Current Link current connections The Current Modules 3P and / or 3PN are arranged in a ring. The connection of the individual elements of the ring is done using SMA connection cables. The SMA connection cables must not be kinked during assembly, as the conductors could be damaged.

  • Page 16: Power Supply

    Mounting of the junction box The connection housing of a current module can be fixed directly to a cable using cable ties. 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.

  • Page 23: Ethernet Installation

    6.5 Ethernet installation 6.5.1 Settings 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/v6 address than another device already installed The device supports both IPv4 and IPv6 communication.
  • Page 24 Network settings Ethernet interface IPv4: Subnet mask For a direct communication between device and PC both devices need to be in the same network when the subnet mask is applied: Example 1 decimal binary 11000000 10101000 00000001 01100101 192.168. 1.101 IP address 11111111 11111111 11111111 11100000...
  • Page 25 IPv4: Mode >> DHCP If a DHCP server is available, alternatively the mode „DHCP“ or „DHCP, addresses only“ can be selected for the Standard interface. The device then gets all necessary information from the DHCP server. The difference between the two modes is that for “DHCP” also the DNS server address is obtained. The settings obtained from the DHCP server can be retrieved locally via the service menu.

  • Page 26: Connection Of The Standard Interface

    Firewall Due to security reasons nowadays, each network is protected by means of a firewall. When configuring the firewall, you have to decide which communication is desired and which have to be blocked. The TCP port 502 for the Modbus/TCP communication normally is considered to be unsafe and is often disabled. This may lead to a situation where no communication between networks (e.g.

  • Page 27: Communication Tests

    6.6 Communication tests Via the service menu on the device website you may check if the selected network structure is valid. The device must be able to reach the DNS server via gateway. The DNS server then allows resolving the URL of the NTP server to an IP address.

  • Page 28: Security System

    6.9 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 29 A maximum of 8 users is supported  3 pre-defined standard users • admin: A user with administrator rights (Default setting password: „CBM_1234“) • localgui: The standard user for the local display. Its permissions determine what can be displayed or changed via the built-in display without a user having to log in.
  • Page 30 When defining / changing passwords the following restrictions must be considered: - Password length 8 up to 32 characters - At least three different types of characters must be used (uppercase, lowercase, numbers, special characters) CAUTION: If login credentials (user name and / or password) of users with write access to the security system are changed, this information must be kept safe.

  • Page 43: Pq Monitoring

    7.6 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. Compliance reports may also be created directly via the website of the device.
  • Page 44 Mains signalling voltage The device monitors mains signalling voltages, which are transmitted in the supply system for control purposes, and records them as events. 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 45: Pq Statistic

    7.6.2 PQ statistic Power quality (PQ) is assessed by a comparison between the PQ parameters measured by the device and the limits of a contract agreed upon.
