Installation Instructions
Shelly Plus 2PM (the Device) is a small form factor 2-channel smart switch which 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 standard electrical wall boxes, behind power sockets and light switches or other places with limited space.
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 it.
CAUTION! The Device must be secured by a cable protection switch in accordance with EN60898-1 (tripping characteristic B or C, max. 16 A rated current, min. 6 kA interrupting rating, energy limiting class 3). If the identification of the Neutral wire is not possible, a two-pole protection switch must be used.
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! Install the Device so that it is not subjected to mechanical stress.
CAUTION! Do not install the Device where it can get wet.
RECOMMENDATION: Connect the Device using solid single-core cables with increased insulation heat resistance not less than PVC T105°C (221°F).
Before starting the mounting/installation of the Device, check that the breakers are turned off and there is no voltage on their terminals. This can be done with a phase tester 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 switch to control 2 load circuits, connect the Device as shown on Fig.1 for AC circuits and on Fig.2 for DC circuits.
Fig.1
Fig. 2
CAUTION! Use the same power supply for the two load circuits and the Device.
For AC circuits connect both L terminals to the Live wire and the N terminal to the Neutral wire. Connect the first load circuits to the O1 terminal and the Neutral wire. Connect the second load circuits to the O2 terminal and the Neutral wire. Connect the first switch to the S1 terminal and the Live wire. Connect the second switch to the S2 terminal and the Live wire.
For DC circuits connect both terminals to the Negative wire and the + terminal to the Positive wire. Connect the first load circuits to the O1 terminal and the Positive wire.
Connect the second load circuits to the O2 terminal and the Positive wire. Connect the first switch to the S1 terminal and the Negative wire. Connect the second switch to the S2 terminal and the Negative wire.
RECOMMENDATION: For inductive appliances that cause voltage spikes during switching on/off, such as electrical motors, fans, vacuum cleaners and similar ones, RC snubber (0.1 µF / 100 Ω / 1/2 W / 600 VAC) should be connected parallel to the appliance. The RC snubber can be purchased at
https://www.shelly.com/en/products/shop/rc-snubber.
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 Web Interface 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 wire and the N terminal to the Neutral wire.
Connect the common motor terminal/wire to the Neutral wire. Connect motor direction terminals/wires to the O1 and O2 terminals.*
Fig. 3
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 wire and the N terminal to the Neutral wire. Connect the common motor terminal/wire to the Neutral wire. Connect motor direction terminals/wires to the O1 and O2 terminals*.
Fig. 4
Fig. 5
Connect the button or the switch to the S1 or the S2 terminal and the Live wire.
If the input is configured as a button in the Device settings, each button press cycles open, stop, close, stop, etc.
If the input is configured as a switch, each switch toggle cycles open, stop, close, stop, etc.
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 wire and the N terminal to the Neutral wire. Connect the common motor terminal/wire to the Neutral wire. Connect motor direction terminals/wires to the O1 and O2 terminals*. and the Live wire. Connect the safety switch to the S2 terminal and the Live wire.
Fig.6
Fig.7
The safety switch can be configured to:
- Stop the movement until the safety switch is disengaged or until a command is sent** and, if allowed in the Device settings, the movement is resumed in the opposite direction until the end position is reached.
- Stop and immediately reverse the movement until the end position is reached. This option requires reverse movement to be allowed in the Device settings
The safety switch can also be configured to stop the movement in only one of the directions or in both.
If you want to use the Device in dual input mode, connect the Device as shown on Fig. 8 for a button inputs or Fig. 9 for a switch inputs. Connect both L terminals to the Live wire and the N terminal to the Neutral wire.
Fig. 8
Fig. 9
Connect the common motor terminal/wire to the Neutral wire.
Connect motor direction terminals/wires to the O1 and O2 terminals*.
Connect the first button/switch to the S1 terminal and the Live wire. Connect the second button/switch to the S2 terminal and the Live wire.
In case the inputs are configured as buttons:
- Pressing a button when the cover is static, moves the cover in the corresponding direction until the endpoint is reached.
- Pressing the button for the same direction while the cover is moving, stops the cover.
- Pressing the button for the opposite direction, while the cover is moving, reverses the cover movement until the endpoint is reached.
In case the inputs are configured as switches:
- Turning a switch on moves the cover in the corresponding direction until an endpoint is reached.
- Turning the switch off stops the cover movement.
If both switches are turned on, the Device will respect the last engaged switch. Turning off the last engaged switch stops the cover movement, even if the other switch is still on.
To move the cover in the opposite direction, the other switch has to be turned off and on again.
Shelly Plus 2PM can detect obstacles. If an obstacle is present, the cover movement will be stopped and, if configured so in the Device settings, reversed until the endpoint is reached.
Obstacle detection can be enabled or disabled for only one of the directions or for both.
RECOMMENDATION: To avoid voltage spikes during switching on/off the cover bi-directional motor, two RC snubbers (0.1 µF / 100 Ω / 1/2 W / 600 VAC) should be connected between the common and the two direction terminals/cables of the cover motor as shown below:
The RC snubber can be purchased at
https://www.shelly.com/en/products/shop/rc-snubber.
Initial Inclusion
If you choose to use the Device with the Shelly Smart Control mobile application and cloud service, instructions on how to connect the Device to the Cloud and control it through the Shelly Smart Control app can be found in the mobile application 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.
