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.
