1.1. Introduction
This document is built for internal or external use. The scope is to suppo pre-sales and
installers to choose, wire and congure the Enel X Way Waymeter™by Gavazzi and provide
a guideline to troubleshoot problems.
This document must be considered as addition to all the ocial materials provided by
Gavazzi (digital or printed).
1.2. Context
When customer plans to migrate its eet to electrical vehicle, it needs to install multiple
charging stations to charge dierent EVs at the same time. Charging stations are high
power electrical infrastructure and if the customer wants to avoid any costly upgrade on
electrical system and avoid high electricity bill, it need a sma way to charge multiple EVs.
With Enel X “Load Optimization Pro” addon, vehicles are charged respecting the residual
available power at customer’s site, balancing the charging power over multiple charging
stations. Fuhermore, if one vehicle requires less power, the “unused” is allocated to the
other vehicles, maximizing the site power connection.
The residual available power is computed take in consideration real-time building metering,
retrieved thank to a metering kit, called Enel X Way Waymeter™Pro.

This checklist will help to pick appropriate meter and sensor.
>1. Verify meter installation location, max amperage and any constraints to pick
appropriate meter (see Annex 1 – Meter comparison and Annex 2 – Sensor comparison)
>a. Mounting: all the meters can be installed on DIN rail. Some meter can also be
installed on panel
>b. Distance Sensors → Meter: is impoant to keep in mind during site design about
the distance between meter and sensors.
>c. In case of needs, meter can be also installed far away from the other kit components
(gateway, modem, etc…). Since communication between meter and gateway is done
via RS485, those 2 components can be also far away (up to 1 km).
>a. Is it possible to bring an ethernet cable from router/switch to the gateway?
>b. If ETH or Wi- → Verify rewall policy on customer’s site (inteacing with site IT
depament and/or facility manager). Po used by Waymeter Pro Kit are listed below
and are all mandatory.
>c. If cellular → verify cellular coverage
>2. Verify connectivity mode
>In case of 5A sensors, distance can be limited. Please refer to Gavazzi calculation
spreadsheet to calculate the max distance.
>In case of 333mV sensors, distance can be signicantly high (up to 20/30 mt).
>Yes → Just use embedded Ethernet connectivity on the gateway
>No → Wi-Fi present→ Add Wi-Fi option
>No → Cellular → Add cellular option (modem adapter + modem) and Enel MVNO

PROJECT DETECTION FROM THE DEVICE
NOTE: Note: this operation is not necessary for the rst conguration of UWP 3
It is recommended, in order to preserve the integrity of the software on the device, that every
time you connect to an instrument, carry out the “reading from the controller” (appropriate
buon on the bar functions as image below) and save the project as a backup on your pc.
FIRMWARE UPDATE
When connected, the controller will check the alignment between your own rmware
and the pc, and in case of dierence, it will identify the update of the same through a red
buon indicating an exclamation point “!”. This indication will be shown next to the string for
entering the IP address of the instrument, as well as in the “system seings” section, under
the appropriate “update rmware” buon.
In case of need for updating:
>1. Be sure that you detect the project from the device, downloading it (not for rst
installation)
>2. Press the appropriate update buon to upgrade the rmware (boom-left corner)
>3. Select the le relating to the new rmware on your PC (le .bin image UWP, the folder
containing the le will open automatically)
