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 voltage spikes during
switching on/off, such as electrical motors, fans, vacuum cleaners and similar
ones, RC snubber (0.1µF / 100 / 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 on 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 O1 and O2 terminals. Connect the I1
terminal to one of circuit breakers and the I2 terminal to the other circuit
breaker.
If you want to use the Device in single input mode connect the device as shown
on Fig. 2 b) for a button input or Fig. 2 c) for a 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 O1 and O2 terminals. Connect
the I1 terminal to one of circuit breakers and the I2 terminal 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 2PM provides safety switch functionality. To
utilize it, connect the device as shown on Fig. 2 d) for a button input or
Fig. 2 e) for a 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 O1 and O2 terminals*. Connect the I1 terminal to one
of circuit breakers and the I2 terminal 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
on Fig. 2 f) for a button inputs or Fig. 2 g) for a switch inputs. Connect the
N terminal to the Neutral cable and the L terminal to the Device power supply

Connect motor direction terminals/cables to the O1 and O2 terminals. Connect
the I1 terminal to one of circuit breakers and the I2 terminal to the other
circuit breaker.
Connect the first button or switch to the S1 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 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® Pro 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® Pro 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 (0.1µF / 100 / 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.
