  • Do not expose to water or high moisture.
  • Do not place on a conductive surface.
  • Do not hotplug Bricks in a stack or Bricklets to a Brick.
  • Try to handle the circuit boards only at the edges to avoid electrical discharge directly to a component.
  • Connecting incompatible devices to external ports (e.g. over-voltage on digital/analog inputs) may result in damage.
  • External actuators, sensors or other peripherals that are connected need to comply with the relevant safety standards for the overall system to be safe.

Bricklets that can be used together with mains voltage

The Solid State Relay Bricklet, Solid State Relay Bricklet 2.0, Dual Relay Bricklet and Industrial Dual Relay Bricklet can be used with 220V/110V mains electricity voltage levels.

If used together with mains voltage level, these Bricklets may only be used by qualified and/or trained electricians. Always follow your national safety regulations.

Before carrying out any work on one of these Bricklets, always disconnect the complete system from all power sources.
