4.1 Installation instruction
The Device is a DIN rail mountable, and it can control a various type of loads (e.g., bulbs) in one
electrical circuit (up to 16 A). It can be fitted inside the breaker box and highly suitable for new
building construction.
⚠CAUTION! Danger of electrocution. Mounting/installation of the Device to the power grid
must be performed with caution, by a qualified electrician.
⚠CAUTION! Danger of electrocution. Every change in the connections must be done after
ensuring there is no voltage present at the Device terminals.
⚠CAUTION! Use the Device only with a power grid and appliances that comply with all
applicable regulations. A short circuit in the power grid or any appliance connected to the
Device may damage it.
⚠CAUTION! Do not connect the Device to appliances exceeding the given max. load!
⚠CAUTION! Allow at least 10 mm of space around each Pro device if you expect currents
higher than 5 A per channel.
⚠CAUTION! Connect the Device only in the way shown in these instructions. Any other method
could cause damage and/or injury.
⚠CAUTION! Do not install the Device where it can get wet.
⚠CAUTION! Do not use the Device if it has been damaged!
⚠CAUTION! Do not attempt to service or repair the Device yourself!
⚠CAUTION! 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 mains voltage
tester or multimeter. When you are sure that there is no voltage, you can proceed to
connecting the wires.
⚠CAUTION! Do not allow children to play with the push-buttons/ switches connected to the
Device. Keep the devices for remote control of Shelly Qubino (mobile phones, tablets, PCs)
away from children.
⚠CAUTION! Do not shorten the antenna.
⚠RECOMMENDATION: Place the antenna as far away as possible from metal elements as they
can cause signal interference.
⚠RECOMMENDATION: Connect the Device using solid single-core cables or stranded cables
with ferrules. The cables should have insulation with increased heat resistance, not less than
PVC T105°C (221°F).
⚠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.
