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 connect the cables.
If you want to use Shelly® Pro 2 PM as a 2-circuit relay, connect the N terminal to the Neutral cable and the L terminal to the Device power supply circuit breaker as shown in Fig. 1. Connect the first load circuit to the 01 terminal and the Neutral cable. Connect the 11 terminal to the first load circuit breaker.
Connect the second load circuit to the 02 terminal and the Neutral cable. Connect the 12 terminals to the second load circuit breaker.
Connect the two switches/buttons to the 31 and S2 terminals and the Device power supply circuit breaker.

CAUTION! Use one and the same phase for both load circuits and the Device power supply circuit.
RECOMMENDATION: For inductive appliances that cause volt-age spikes during switching on/off, such as electrical motors, fans, vacuum cleaners, and similar ones, RC snubber (0.1pF / 100 0 / 1/2 W / 600 VAC) 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® Pro2PM 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, but they can be used for URL actions. If you want to use the Device in detached mode connect the device as shown in Fig. 2 a).
Connect the N terminal to the Neutral cable and the L terminal to the Device power supply circuit breaker. Connect the common motor terminal/cable to the Neutral cable. Connect motor direction terminals/cables to the 01 and 02 terminals. Connect the 11 terminals to one of the circuit breakers and the 12 terminals to the other circuit breaker. If you want to use the Device in single input mode connect the device as shown in Fig. 2 b) for a button input or Fig. 2 c) for switch input. Connect the N terminal to the Neutral cable and the L terminal to the Device power supply circuit breaker. Connect the common motor terminal/cable to the Neutral cable. Connect mo-tor direction terminals/cables to the 01 and 02 terminals.
Connect the 11 terminals to one of the circuit breakers and the 12 terminals to the other circuit breaker. Connect the button or the switch to the S1 terminal and the Device power supply circuit breaker. 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® Pro 2 PM provides safety switch functionality.
To utilize it, connect the device as shown in Fig. 2 d) for a button input or Fig. 2 e) for switch input. Connect the N terminal to the Neutral cable and the L terminal to the Device power supply circuit breaker. Connect the common motor terminal/cable to the Neutral cable. Connect motor direction terminals/cables to the 01 and 02 terminals*. Connect the 11 terminals to one of the circuit breakers and the 12 terminals to the other circuit breaker. Connect the controlling button or switch to the S1 terminal and the Device power supply circuit breaker. Connect the safety switch to the S2 terminal and the Device power supply circuit breaker. 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 in Fig. 2 f) for button inputs or Fig. 2 g) for switch inputs. Connect the N terminal to the Neutral cable and the L terminal to the Device power supply circuit breaker. Connect the common motor terminal/cable to the Neutral cable. Connect mo-tor direction terminals/cables to the 01 and 02 terminals.
Connect the 11 terminals to one of the circuit breakers and the 12 terminals to the other circuit breaker. Connect the first button or switch to the Si terminal and the Device power supply circuit breaker. Connect the second button or switch to the S2 terminal and the Device power supply circuit breaker. 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 in the same direction while the cover is moving, stops the cover.
– Pressing the button in 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® Pro 2 PM 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® Pro 2 PM 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 (0.1pF / 1000 / 1/2W / 600V AC) should be connected between the common and the two direction terminals/cables of the cover motor as shown on Fig. 3. The RC snubbers can be purchased at https://shop.shelly.cloudirc-snubber-witi-smart-home-automation
