ENERGY METER INSTALLATION GUIDE
This document provides installation instructions for theIYILO
energy management systems
Grid
Electrical panel
Important Notice Before Installation
1. Please install the IYILO Energy Meter according to the instructions below. Improper installation
or misuse may result in connection failure or inaccurate performance.
2. Please do not use any NON-IYILO branded or unauthorized energy meters for installation.
Unauthorized meters will not support energy load management and may lead to potential
malfunction or failure of product features.
3.This type of installation involves certain risks and is recommended to be performed by a
licensed electrician. Please strictly follow the NEC Code and all applicable local codes.
4. Please ensure this IYILOcharger is upgraded to the latest firmware version.
5. The RS485 communication cable is not included with the product. To ensure reliable communi-
cation between the IYILO charger and the external energy management system, it is strongly
recommended to use 2 Core Twisted Pair Shielded Cable (two insulated twisted wires with a
shielding layer; twist the drain wire into a single strand before connecting) specifically designed for
RS485 Commnication.
6.The IYILO Energy Meter can measure current up to 200A
Please install according to the layout diagram below & the load balancing layout diagram.
2-1 Remove the quick connector
and twist the two components
counterclockwise to separate it
into three parts.
2-2 As shown in the illustration,
pass the RS485 communication
cable sequentially through
component ③ and component
②.
2-3 Use a screwdriver to turn
the screw in component ①
counterclockwise four full turns to
loosen it. (Turning too many times may
cause the screw to fall out, making it
difficult to handle.)
2-4 Insert the metal conductor part of
the communication
cable into component ①. You
can record the corresponding wire
harness in the table below.
Please connect the shield drain wire
to Terminal 1（Twist the drain wire
strands together before connection）
2-5 Assemble components
② and ①

Step 1: Communication Cable Stripping Procedure
Step 2: Connect Communication Cable to Quick
Connector
1-1, First, strip approximately 0.8 inches of the communication cable outer jacket.
1-2, Strip approximately 0.2 inches of the communication cable inner insulation.
1-3, Finally, expose 0.2 inches of the metal conductor and 0.6 inches of the inner insulation.

1-WHATS IN THE BOX?
RS485 Communication Cable: Option1: Recommend use 2 Core Twisted Pair Shielded Cable
(two insulated twisted wires with a shielding layer; twist the drain wire into a single strand
before connecting)
Option 2:2 Conductor Stranded Copper Shielded Cable (for short runs under 20 meters)
Note: Use a wire stripper to prepare the communication cable insulation for connection
(improper stripping dimensions may result in water ingress risk).

Step 1. Meter Power Supply Installation
Step 2. Connect the CT clamp
1-1 Remove the lower cover panel
of the meter to prepare for wiring.
1-2 Connect the live wire (red):
insert the conductor end into terminal
5 of the meter, and connect the bare
stripped end to the circuit breaker.
1-3 Connect the netural wire (Black):
insert the conductor end into terminal 6
of the meter, and connect the bare
stripped end to the neutral bar
1-4 Power on and test: the screen
lighting up indicates successful meter
power-up.
1-5 Turn off the meter power and
reinstall the cover panel removed in
step 1-1.

Step 3. RS485 Communication Cable Connection at
the Meter Side
3-1 Route the communication cable, which has already been connected to the charger side, to the
vicinity of the home electrical panel (maximum length should not exceed 300 ft).
3-2 Use wire strippers to remove approximately 0.2 inches (5 mm) of insulation from the cable's
conductor
3-3 Connect the wires according to the following wiring table.
Wire according to the [EV Charger RS485 Port Installation] step 2 table 1.
4-1 Place the upper cover panel back in position
4-2 Turn on the smart meter power supply and open the app.
4-3 In the app, Tap the Advanced ,then selected load balancing
4-4 Enable Dynamic load balancing ; Confirm real-time meter reading appear
4-5 Enter your household breaker rating to finish setup.
▲Important: Check Your Installation Before Use. This meter is designed to work only with the
following electrical setup:
3-wire system (2 hot wires and 1 neutral)
Voltage between phases: 208–240 V
Voltage between phase and neutral: 120 V
Warning: To prevent electric shock or injury, always turn off the main breaker of the
electrical panel before proceeding with the meter installation.
Energy Meter Installation in Electrical Panel Preparation Required：
3-1Remove the Cap from the Plug
3-2 Connect the quick connector

Note: 1.The IYILO EV Charger requires a power supply (less than 0.1A). You can connect the
power cord of the energy meter to an appropriate circuit breaker, which can be shared with an
existing breaker if available.
2.The rated voltage of the meter is 100-277V.
3.The power cord is pre-scored at the bare wire section. Please remove the outer insulation
before use.
Note: When installing the clamp, the arrow should point towards the internal
