XEM470 Flow Energy Management Controller

XEM470
Danger of death by electric shock.
Live components carry potentially fatal voltages.

• Before starting any installation or maintenance work, switch off the power to the distribution board and secure to prevent itbeing switched on again accidentally.
• Make sure that the conductors to be connected to the meter are voltage-free.
• All installation and maintenance work on this unit must be carried out by a trained and authorised electrician.

The Energy Management Controller is supplied with power via outer conductor L1. At least the outer conductor L1 and neutral conductor N need to be connected for the
unit to switch on.

Introduction

flow connects the electrical system to the main producers and consumers of the installation in a modular way. Once installed in the meter cabinet, flow monitors and controls
the electrical energy dynamics in your home in a modular and flexible manner, by measuring and controlling devices like electric storage system, electric vehicles, heating
system and photovoltaic installation. It prevents your domestic electrical supply from being overloaded and optimize the consumption and energy flows.

Safety instructions

Danger of death by electric shoc

k.

• Live components carry potentially fatal voltages.
• Only use the Energy Management Controller in a dry environment and keep it away from liquids.
• Install the Energy Management Controller only in approved enclosures or distribution boards downstream of the electricity supply company’s meter so that the connections for the outer and neutral conductors are located behind a cover or guard to prevent accidental contact.
• Before starting any installation or maintenance work, switch off the power to the distribution board and secure to prevent it being switched on again accidentally.
• Maintain the prescribed minimum distances between the network cable and mains voltage installation components or use suitable insulation.

Avoid damage to or destruction of the Energy Management Controller

• Do not connect an ISDN cable to the Energy Management Controller’s networkconnection.
• Damage to or destruction of the EnergyManagement Controller by voltage surgeson the network cable.
• If network cables are installed outside thebuilding, voltage surges can be caused bylightning strike, for example.
• If installed outside the building, the networkcable must be protected with suitable overvoltage protection.
• Protect your solar installation with invertersusing suitable overvoltage protection.
• Damage to or destruction of the EnergyManagement Controller by improper use.
• Do not operate the Energy Management Controller outside the specified technical tolerances.
• The LAN1/2 Ethernet interface of the connected unit must meet the safety extralow voltage requirements.

Product description

Modbus interface

Note the following points when connecting external devices to the RS485 Modbus RTU interface of the Energy Management
Controller:
Requirement for the cable:

• Nominal voltage/wire insulation: 300 V RMS
• Cable cross section: 0.25 … 1.5 mm²
• Cable type: Rigid or flexible
• Recommendation: Use AlphaWire standard cable, designation 2466C. Alternatively, a CAT5e cable can also be used.

Requirement for cable installation:

• In the area for connecting the RS485 Modbus RTU interface on the Energy Management Controller, mechanical means must be provided to ensure that individual wires of the connecting cable are at least 10 mm away from live parts.
• The connecting cable must be run separately from the mains cables in the distribution board and on the permanent link.
• The RS485 Modbus RTU interface of the connected unit must meet the safety extra low voltage requirements.

Electrical connection for direct  measurement

It must be ensured by fitting the according protection that the maximum permitted current per phase (63A) is not exceeded.

1. Install the Energy Management Controller on a DIN rail.
2. Connect the conductors to the Energy Management Controller. Do not exceed the permitted connection cross section and tightening torque for the screw terminals
   (see section “4. Technical data”):
   • For a three phase power network, connect the outer conductors L1, L2 and L3 and the neutral conductor N to the
   Energy Management Controller as shown in the connection diagram.
   • For a single phase power network, connect the outer conductor L1 and neutral conductor N to the Energy Management Controller as shown in the connection diagram.
   The following figure contains a connection example.
   Check correct allocation of the phases Make sure that the phases are all correctly allocated, otherwise the Energy Management Controller will return incorrect measured values and failed to ensure overload protection
   .In case of combination with a Storage System, please follow the wiring diagram of the system/ storage.

Electrical connection for indirect measurement with current transformers

1. Install the Energy Management Controller on a DIN rail. To do this, hook the XEM470 onto the top edge of the DIN rail and press down until it latches into place.

2. Connect a current transformer to each outer conductor L1, L2 and L3.
   **** Danger of death by electric shock at the current transformer terminals.
   Due to the type of connection, there is a mains voltage of 230 V present at conductors k/s1 and l/s2. To prevent accidents, put up a notice with this information at this location on site.

3. Connect a cable for the secondary current measurement to terminals k/s1 and I/s2 on  each current transformer. Do not exceedthe permitted connection cross section for the Energy Management Controller (see section “4. Technical data”).

4. Connect the connecting cable for the current measurement to the Energy Management Controller and do not exceed the permitted tightening torque for screw
   terminals (see section “4. Technical data”).

5. Connect the connecting cables for the voltage measurement to the outer conductors L1, L2 and L3.

The following figure contains a connection example.

• Make sure that at least the top/outer conductor L1 and the neutral conductor N are connected to the Energy Management Controller.
  The NET LED lights up or flashes orange or red.
  The EMC isn’t connected properly on our cloud.

• Check the house internet connection

• Check the ethernet cable connection

• Check if an error occur on https://flow.hager.com/

• Restart the EMC

• The IP configuration isn’t set properly.
  The APP LED flashes orange or red.
  Orange: an alert occur on the installation, see https://flow.hager.com to see the detail. Red: a critical error occur on the installation, see https://flow.hager.com to see the detail.

• Restart the EMC could solve the issue.
