Product Introduction
Shelly® is a line of innovative microprocessor-managed devices, which allow
remote control of electric appliances through a mobile phone, tablet, PC, or
home automation system. Shelly® devices can work standalone in a local Wi-Fi
network or they can also be operated through cloud home automation services.
Shelly Cloud is such a service that can be accessed using either Android or
iOS mobile application, or with any internet browser at
https://home.shelly.cloud/. Shelly® devices
can be accessed, controlled and monitored remotely from any place where the
User has internet connectivity, as long as the devices are connected to a Wi-
Fi router and the Internet. Shelly® devices have embedded Web Interface
accessible at http://192.168.33.1 in the Wi-Fi
network, created by the device in Access Point mode, or at the URL address of
the device in the Wi-Fi network it is connected to. The embedded Web Interface
can be used to monitor and control the device, as well as adjust its settings.
Shelly® devices can communicate directly with other Wi-Fi devices through HTTP
protocol. An API is provided by Allterco Robotics EOOD.
For more information, please visit:
https://shelly-api-docs.shelly.cloud/#shelly-family-overview.
Shelly® devices are delivered with factory-installed firmware. If firmware
updates are necessary to keep the devices in conformity, including security
updates, Allterco Robotics EOOD will provide the updates free of charge
through the device embedded Web Interface or Shelly Mobile Application, where
the information about the current firmware version is available. The choice to
install or not the Device firmware updates is User’s sole responsibility.
Allterco Robotics EOOD shall not be liable for any lack of conformity of the
Device caused by failure of the User to install the provided updates in a
timely manner.

Installation Instructions
The Triple Phase Wi-Fi Energy Meter, Shelly 3EM by Allterco Robotics is intended to be mounted next to the breakers, in order to monitor the electric power through it, independent for each channel and heavy-duty contactor control. Shelly may work as a standalone Device or as an accessory to a home automation controller. Shelly 3EM can measure in comming and outgoing energy.
- Purpose of control: Operating
- Construction of control: Independently mounted
- Type 1.B Action
- Pollution Degree 2
- Impulse Voltage: 4000 V
Depending on how many phases you want to measure, you have to connect your Shelly 3EM according to the provided scheme.
CAUTION! Danger of electrocution. Mounting/installation of the Device to
the power grid has to be performed with caution, by a qualified electrician.
CAUTION! Danger of electrocution. Every change in the connections has to
be done after ensuring there is no voltage present at the Device terminals.
CAUTION! Use the Device only with a power grid and appliances which comply
with all applicable regulations. A short circuit in the power grid or any
appliance connected to the Device may damage the Device.
CAUTION! Do not connect the Device to appliances exceeding the given max
load!
CAUTION! Connect the Device only in the way shown in these instructions.
Any other method could cause damage and/or injury.
CAUTION! Do not install the Device where it can get wet.
- First step is to install the measuring clamps over the wires. Open the current transformer with screwdriver then clamp it over the desired power cable. Do this for all the current transformers, please follow the current flow diagram.
On the bottom of your Split core transformer, you will see an arrow showing the direction of the energy flow.

CAUTION! Connect the current transformers accordingly for each channel! Each current transformer is marked and calibrated for the respective input of the Device. Any improper connection will lead to incorrect device measurement and visualisation.
Initial Inclusion
If you choose to use the Device with the Shelly Cloud mobile application and
Shelly Cloud service, instructions on how to connect the Device to the Cloud
and control it through the Shelly App can be found in the “App Guide”
www.shelly.cloud/app-guide.
The Shelly Mobile Application and Shelly Cloud service are not conditions for
the Device to function properly. This Device can be used standalone or with
various other home automation platforms and protocols.
CAUTION! Do not allow children to play with the buttons/switches connected
to the Device. Keep the Devices for remote control of Shelly (mobile phones,
tablets, PCs) away from children.
