INSTALLATION PROCEDURE

General safety information

Install current transformers and corresponding measuring devices only when the power supply of the system is disconnected.
- Installation and service should be performed by a qualiﬁed licensed electrician. The installer is responsible for all (regional-specific) electrical requirements.
Do not use this device in installations where grid fallout can be life-threatening.
- We do not guarantee that the system will not trigger an overcurrent, leading to tripping of overcurrent protections

Installation of the coils

An indicator on the coil shows the direction of the current ﬂow. It should thus point from the grid towards the building. Please make sure that the coil is mounted correctly around the conductor(s) in the installation cabin.

The coils should be placed around the conductors bringing the grid into the electrical cabinet, before the current distribution to the building and charge islands.
The Rogowski coil is a split core coil, it can be unlocked and can be mounted around the conductor(s).

Example:

Example of a connection diagram

A type B circuit breaker of 16A is recommended to be installed in front of the EMpro measuring device.
After the circuit breaker, the connections can be wired with the following wires: voltage (rigid/ﬂexible): 0.5 mm² … 2.5 mm² / 0.5 mm² … 4 mm² supply (rigid/ﬂexible): 0.14 mm² … 2.5 mm².

L1 and N can be split to also provide power to the power supply for the measuring device.

CONFIGURATION KEYS

Related to the eDLB Device (not license related)

These conﬁg presets are important when installing an eDLB measurement device, AND should be set on the master of the charging island.

When using EnoSAM, select eDLB from the ‘measurement device’ dropdown.
You can also select the grid type (DELTA, PHASE1 or WYE) and set the Grid’s maximum current.
After you’ve set everything to your liking, click the APPLY button to implement these conﬁgurations.

Smart.external.limit.device (read/write)

This conﬁguration should be set when a measuring device is connected.
For the conﬁguration of the Phoenix EEM-MA371, this value should be set on “eDLB” (e.g. smart, external, limit, device = eDLB)

Installation.grid.max.current (read/write)

The value which is set in this conﬁguration indicates the total maximum available current of the installation. This is the value of the main MCB of the building, which uses an eDLB to help prevent it from tripping.
This is the same maximum current which will go through the Rogowski coils of the measuring device.

The standard preset value of this conﬁguration is 40A (e.g. installation, grid.max.current = 40.0)

Smart.external.limit.limit.margin (read/write)

This is an extra safety offset margin on the installation.grid.max.current to limit the possibility of overcurrent of the grid.

To limit possible fallout due to current peaks, set this parameter to 0.90. (e.g. smart.external.limit.limit.margin = 0.95)

Smart.external.limit.fallback.limit.current (read/write)

This value replaces the “installation.grid.max.current” when an eDLB measuring device is disconnected from the master of the charging island. The standard preset value of this configuration is 8A

(e.g. smart.external.limit.fallback.limit.current = 8)

Smart. external. limited edlb.endpoint (read/ write)

This config contains the static IP address set in the EEM-MA371.

If this value does not match the IP address, no data can be read from the eDLB device.
(e.g. smart, external, limit, edlb.endpoint = http://192.168.11.30:80/)

HouseUsedCurrents (read only)

These values show the measured current from the measuring device on L1, L2, and L3 in amperes
(e.g. HouseUsedCurrents = 1.469,2.866,4.896)

HouseVoltages (read only)

These values show the measured voltages from the measuring device between L1-N, L2-N, L3-N in volts (e.g. HouseVoltages = 215.786,213.228,212.67)

HouseUsedPowers (read only)

These values show the measured power from the measuring device on L1, L2, L3 in watts (e.g. HouseUsedPowers = 233.793,128.112,11.465)

Related to the charge point

These configuration keys are unique for each charge point AND should be configured on each charge point in the island.

Chargepoint.custom.max.current (read/write)

This configuration sets the maximum current for the charge point. Important: this value should never exceed the maximum permissible current of the power supply cable of the charge point
(e.g. chargepoint.custom.max.current = 32.0)

Related to the charge island, set on the master

These configuration keys are important when configuring a charging island AND should be set on the master of the charging island.

Smart.local.cable.limit.current (read/write)

The value which is set in this configuration indicates the maximum permissible current of the charging island group.

Important: this value should never exceed the maximum permissible current of the supply cable towards the charging island. The standard preset value of this configuration is 1000A.
NOTE: In case of an eDLB device configuration, this value is always less than or equal to the “installation.grid.max.current” (e.g. smart.local.cable.limit.current = 1000)

FALLBACK SCENARIOS

NOTE: The behaviour of these scenarios may have changed due to software updates of the charging islands; always check for the latest manual of your chargers and the eDLB.

Disconnected measuring device

This scenario can occur with a star, a daisy or a hybrid configuration.

Situation

The Ethernet connection of the measuring device is disconnected.

Behavior

The master will fall back to the current, which is set in the following configuration: smart.external.limit.fallback.limit. current

This current will be distributed over all charge points in the charging island. The backend is informed about the disconnection.
Backend message: {“connectorId”: 0, ”status”:” Available”, errorCode”:” PowerMeterFailure”, ”info”: ”unable to retrieve currents from eDLB”, “timestamp”:”<datetime>”}

Disconnected the master from the backend

This scenario can occur with a star, a daisy or a hybrid configuration.

Situation

The master of the charging island is disconnected from the backend.

Behavior

This situation does not impact the load balancing algorithm of the charging island.
NOTE: Only when the connector.limit.current.offline = true, the connector of the master will fall back to the current, which is set in the connector. limit. current.offline.max.

This configuration is unique per connector per charge point. This means it can be configured differently on each charge point in the charging island

Disconnected the master from the charging island

This scenario can occur with a star, a daisy or a hybrid configuration.

Situation

The master of the charging island is disconnected from the charging island.

Behavior

Island: The island will fall back to the current set in config “smart. external.limit.fallback.limit.current“ because the DPM device is disconnected.

Master:

The master reserves the current set in the config connector. limit. current. Offline.max on the master, per disconnected satellite, from the available fallback current in the charging island.

Satellite:

If connector.limit.current.If offline = false, the current limit of the satellite will not change. If it is equal to true, however, the current limit of the satellite will fall back to the current, which is set in connector.limit.current.offline.max.

Disconnected satellite

This scenario can occur with a star, a daisy or a hybrid configuration. If this scenario occurs in a daisy setup, the result will be a Disconnect measuring device as mentioned in chapter 7.1.

Situation

Somewhere on the island, a satellite is disconnected from the charging station.

Behavior

Island: No change when the DPM device is still connected to the master.

Master:

The master reserves “x” amperes per disconnected satellite from the available current in the charging island.
The amount of amperes is set in pthe arameter connector. limit.current.offline.max on the master.
Disconnected satellite: connector, limit, current.offline = false

The current limit of the satellite will not change. connector.limit.current.offline = true
The current limit of the satellite will fall back to the current, which is set in the connector.limit.current.offline.max.
WARNING: This behaviour is guaranteed only as long as the master is not rebooted, After reboot, the amount of satellites detected by the charging island might be changed.
