Product description

The Bosch Power Meter PM7000i is a bidirectional meter with LAN/Ethernet interface. The Pm7000i transfers the data encrypted to the Energy Manager from Bosch or My Energy Master from Buderus. At least one Bosch Power Sensor PS7000 is required additionally in order to be able to detect the energy flows of an inverter or energy storage device.

Operation of the PM7000i from 45 °C

Ambient temperature
Danger to life due to electric shock or fire
For ambient temperatures higher than 45 °C, there is a danger to life due to electric shock or fire.

• Continuous operation of the PM7000i from 45 °C is not permissible.

Electric connection

H Danger to life from electric shock
Dangerous voltages are present on live components.

• Before installation or maintenance work, switch the electrical distributor voltage-free.
• Secure against unintentional reconnection.
• Ensure that the conductors that should be connected to the Pm7000i are deenergised. Installation and maintenance work on this PM7000i must be carried out only by an authorized electrician.

The PM7000i is supplied with current via the powered conductor L1. At least the powered conductor L1 and the neutral conductor N must be connected so that the PM7000i can measure the energy currents correctly and be put into operation.

Electrical connection for direct measurement

• Using a fuse, ensure e.g. that the maximum permissible current per phase is not exceeded.
• Mount the PM7000i on the mounting rail:
  • Hook the PM7000i in on the upper edge of the mounting rail.
  • Press on the PM7000i until it snaps into place.
• Connect the conductor to the PM7000i. In doing so, observe the permissible connection cross-section and tightening torque for screw terminals.
  • With a three-phase mains power supply, connect powered conductor L1, L2 and L3 as well as the neutral conductor to the PM7000i according to the connection diagram (Figure 2).
  • ith a single phase mains power supply, connect powered conductor L1 and neutral conductor N to the PM7000i according to the connection diagram.

Beware of incorrect measurements
An incorrect assignment of the phases provides the PM7000i with incorrect measurements.

• Ensure that the phases are each assigned correctly:
  L1, L2, L3: powered conductor
  N: neutral conductor
  OUT: meter output, consumer side
  IN: meter input, mains voltage side

When connecting appliances with a fuse protection of more than 16 A, a 16 A fuse ≤ must be provided for the sensor.
The figure shown is a connection example. It must be possible for the end user to de-energies the PM7000i by means of a freely accessible meter fuse or an additional circuit breaker. For correct operation, the PM7000i must always be connected to the Energy Manager app from Bosch or My Energy Master app from Buderus as well as to at least one PS7000 for measuring the energy flows of an inverter. Optionally, the PM7000i can be combined with a maximum of three PS7000 meters in order to measure the energy flows of additional inverters or energy storage devices.

Connection of the PS7000 to the RS485 interface

The following points must be observed for the connection of the PS7000 to the RS485 interface of the PM7000i.

• Requirements on the cable:

  • rated voltage / cable insulation: 300 V RMS
  • Cable cross-section: 0.25 to 0.5 mm2
  • Cable type: rigid or flexible
  • Recommended: use the standard-cable from AlphaWire with designation 2466C. Alternatively, a CAT5e cable can also be used.

• Requirements on routing:

  • In the connection area of the RS485 interface of the PM7000i, it must be mechanically ensured that individual wires of the connecting cable have a distance of at least 10mm to live parts.

  • The connecting cable must be routed separately from the power cables in the distributor and on the installation route.
    For more information:

  • observe the installation instructions of the PS7000.

Commissioning the PM7000i

Commissioning of the PM7000i is carried out using the Energy Manager app
(Buderus: MyEnergyMaster).

• Energy Manager for iOS or Android
  

• MyEnergyMaster for iOS or Android
  

For safety-relevant aspects, Bosch Thermotechnik GmbH explicitly recommends allowing updates for the Power Meter PM7000i.

• Call up the web service interface of the  PM7000i (Chapter 16).
• Activate “Automatic Updates”.

Before starting with the actual commissioning of the PM7000i, the following steps for commissioning must be completed:

• Download the Energy Manager app (heat pump from Bosch) or the MyEnergyMaster app (heat pump from Buderus) for Android or iOS.
• Open the app and click on the “Start commissioning” button on the third intro screen. Complete activation of the Energy Manager (enter activation code, or if not at hand, start the 30 day trial version and complete activation at a later time)
• Connect the Energy Manager and follow the instructions in the app.
• Connect the measuring device to the mains power supply point – PM7000i using the Energy Manager.
• Select “Bosch Power Meter”.
  • If a Fronius inverter compatible with the app and the PM7000i are installed in one system: select the menu item “Both”.
• Observe the notices on electrical installation, the correct connection of the PM7000i (enclosed instructions) and the LED for the network status.
• Scan the QR code enclosed in the packaging of the PM7000i or printed on its data plate or enter the serial number manually so that the Energy Manager can find the PM7000i in the local network.
• Apply a safety verification.
  • Press the reset button with a tipped object once for longer (between 0.5 – 2 s) and then briefly once within 1 s (maximum 0.5 s).
• The status LED of the PM7000i flashes orange twice briefly to confirm. The PM7000i has now been successfully connected to the Energy Manager.

Measuring other consumers

The PS7000 is required to measure other generators (e.g. inverters or energy storage devices). The sensor is equipped with folding transformers that can measure the current flow of each individual phase connected to the generator.
For installation and further information:

• Observe the operating instructions of the PS7000.

Web service interface PM7000i

• Necessary only for service purposes and for troubleshooting, not for commissioning.
• Access by means of entering the IP address in the web browser
• Open browser.
• Enter “https://192.168.3.99” as well as the password which can be found on the data plate or pack label of the PM7000i.

Reset network settings of the PM7000i

• Press the reset button with a tipped object as follows:
  • once briefly (maximum 0.5 s)
  • then, within 1 s: once for longer (between 3 – 5 s)
    The status LED of the PM7000i flashes orange twice briefly to confirm.

Reset the password of the PM7000i

The password and the QR code are safety relevant for the product.

• Do not forward information to third-parties. To reset the password of the PM7000i:
• Press the reset button with a tipped object as follows:
  • once for longer (between 3 – 5 s)
  • then, within 1 s: once briefly (maximum 0.5 s)
• The status LED of the PM7000i flashes orange twice briefly to confirm.

The password is necessary for access to the local web service interface of the PM7000is – for example, if a static IP address is to be assigned.
If the command has been recognized correctly, the status LED flashes orange twice (Chapter 12). The password is reset to the as-delivered condition (data plate on the PM7000i).

Restart the PM7000i

• Press the reset button with a tipped object once for longer (at least 6 s).
  If the command was recognized correctly, all LEDs switch off and the PM7000i restarts.
