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 Allter- co 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.

Shelly® Plus line offers PM products capable of real-time precise power measurement.

Control your home with your voice

Shelly® devices are compatible with Amazon Alexa and Google Home supported functionalities. Please see our step-by- step guide on: https://shelly.cloud/support/compatibility/.

Installation Instructions

Shelly® Plus 2PM (the Device) can control 2 electrical circuits, including a bi-directional AC motor. Each circuit can be loaded up to 10 A (16 A total for both circuits) and its power consumption can be measured individually (AC only). It can be retrofitted into a standard in-wall console, behind power sockets and light switches or other places with limited space.

Danger of electrocution. Mounting/installation of the Device to the power grid has to be performed with caution, by a qualified electrician.

Danger of electrocution. Every change in the connections has to be done after ensuring there is no voltage present at the Device terminals.

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.

Do not connect the Device to appliances exceeding the given max load!

Connect the Device only in the way shown in these instructions. Any other method could cause damage and/or injury.

Do not install the device at a place that is possible to get wet.
warning RECOMMENDATION
Connect the Device using solid single-core cables with increased insulation heat resistance not less than PVC T105°C.
Before starting installing/mounting the Device, wire check that the breakers are turned off and there is no voltage on their terminals. This can be done with a phase meter or multimeter. When you are sure that there is no voltage, you can proceed to connecting the cables
If you want to use the Device as a relay switch to control 2 load circuits, connect the Device as shown on Fig. 1 for AC circuits and on Fig. 2 for DC circuits.

Use the same power supply for the two load circuits and the Device.
For AC circuits connect both L terminals to the Live cable and the N terminal to the Neutral cable. Connect the first load circuits to the O1 terminal and the Neutral cable. Connect the second load circuits to the O2 terminal and the Neutral cable. Connect the first switch to the S1 terminal and the Live cable. Connect the second switch to the S2 terminal and the Live cable.
For DC circuits connect both L terminals to the Negative cable and the N terminal to the Positive cable. Connect the first load circuits to the O1 terminal and the Positive cable. Connect the second load circuits to the O2 terminal and the Positive cable. Connect the first switch to the S1 terminal and the Negative cable. Connect the second switch to the S2 terminal and the Negative cable.
warning RECOMMENDATION: For inductive appliances that cause voltage spikes during switching on/off, such as electrical motors, fans, vacuum cleaners and similar ones, RC snubber (0.1µF / 100Ω / 1/2W / 600V AC) should be connected parallel to the appliance.
The RC snubber can be purchased at https://shop.shelly.cloud/rc-snubber-wifi-smart-home-automation As a cover controller Shelly® Plus 2PM can work in 3 modes: detached, single input or dual input.
In detached mode, the Device can be controlled through its WebUI and the App only. Even if buttons or switches are connected to the Device, they will not be allowed to control the motor rotation in detached mode.
If you want to use the Device in detached mode connect the device as shown on Fig. 3: Connect both L terminals to the Live cable and the N terminal to the Neutral cable. Connect the common motor terminal/cable to the Neutral cable. Connect motor direction terminals/cables to the O1 and O2 terminals.*
If you want to use the Device in single input mode connect the device as shown on Fig. 4 for a button input or Fig. 5 for a switch input. Connect both L terminals to the Live cable and the N terminal to the Neutral cable. Connect the common motor terminal/cable to the Neutral cable. Connect motor direction terminals/cables to the O1 and O2 terminals*.
Connect the button or the switch to the S1 or the S2 terminal and the Live cable.
If the input is configured as a button in the Device settings, each button press cycles open, stop, close, stop...
If the input is configured as a switch, each switch toggle cycles open, stop, close, stop...
In single input mode Shelly® Plus 2PM provides safety switch functionality. To utilize it, connect the device as shown on Fig. 6 for a button input or Fig. 7 for a switch input. Connect both L terminals to the Live cable and the N terminal to the Neutral cable. Connect the common motor terminal/cable to the Neutral cable. Connect motor direction terminals/ cables to the O1 and O2 terminals*.
Connect the controlling button or switch to the S1 terminal and the Live cable. Connect the safety switch to the S2 terminal and the Live cable.
