⚠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.
⚠CAUTION! 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.
⚠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.
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 cable and the N terminalto 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 first button/switch to the S1 terminal and the Live cable. Connect the second button/switch to the S2 terminal and the Live cable.
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, Shelly® Plus 2PM 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.
