Installation Instructions :

a. Hardware installation :

STEP 1

to the Mains Supply. The phase wires (phase 1, phase 2, and phase 3) and the neutral wire

must be connected to this terminal. These connection points are represented as T1, T2, T3

and TN in the diagram below. Place the 3-Phase IoT Energy Meter close to this terminal.

for 3 phase (star type) load systems. For 1-phase, 2-phase and 3-phase delta loads, the

installation process stays the same. Contact info@buildingpulse.org for more info.

Installation Instructions : This document outlines the steps involved in installing the Smart Energy Meter/Analyzer for 3 phase (star type) load systems. For 1-phase, 2-phase and 3-phase delta loads, the installation process stays the same. Contact info@buildingpulse.org for more info. a. Hardware installation : STEP 1 : Identify the 3 Phase load you’d like to monitor, along with the terminal connecting it to the Mains Supply.

STEP 2 : After identifying the terminal, switch off the load connected to that terminal. Also, as a precaution, switch off the mains supply entering into that terminal. Please use a tester screwdriver to ensure there’s no current flowing through the terminal. Next, carefully remove the load wires from the terminal - remove only those wires that are directly connected to the load you wish to monitor, ie. phase 1, phase 2, phase 3 and neutral wire going into the load.

STEP 3 : Insert the Current Transformers (CTs) provided into each of the phase wires - a CT should be inserted into the phase 1 wire, another CT should be inserted into the phase 2 wire, and a third CT should be inserted into the phase 3 wire. Each CT will have 2 faces - a P1 face and a P2 face (as mentioned on the CT). Each CT must be placed in such a way that the P1 face will experience the flow of current through the wire first once the load operates (please refer to the diagram below).

STEP 4 ; The 3-Phase IoT Energy Meter will have two sets of wires - a set of four connection wires (a black connection wire, a red connection wire, a blue connection wire and a white connection wire), and a set of CT wires. The CT wires are paired in groups of two - there are three such groups in total. Each group is labelled as either “1”, “2” or “3”. Connect each connection wire to the terminal in the following manner : a.

STEP 5 : After all connections have been securely made, re-connect the load to the terminal by connecting the load’s phase 1 wire to terminal T1; the load’s phase 2 wire to terminal T2; the load’s phase 3 wire to terminal T3 and the load’s neutral wire to terminal TN. Make sure all connections are tightly secured.

b. WiFi integration : 1. After ensuring all connections are secure, turn on the mains supply and the load. After about 60 seconds, a WiFi network named “New_WiFi_Setup” will appear. 2. Connect to “New_WiFi_Setup”. If you’re prompted to enter a password, enter “738738738” as the password.

3. Next, open a web browser, such as Chrome or Firefox, and enter “192.168.4.1” in the address bar. 4. The “WiFiManager” page will open upon pressing enter. Select “Configure WiFi”.

5. Select the WiFi network you wish to pair the IoT Energy Meter with. Enter the password for the network. The IoT Energy Meter will transmit its energy readings to the bpulse web-portal via this particular WiFi network. 6. Once you hit “Save”, the “New_WiFi_Setup” network will disappear. The IoT Energy Meter is now successfully installed. Note : Please do not press any of the buttons on the IoT Energy Meter’s display screen. This might change the meter’s configuration/settings.
