3. Only connect or disconnect cables and adjust the DIP switch when the power is disconnected in zone 2.
4. Snap the device onto or off the pace-Bus 9294 or connect and disconnect the cables only when the power is disconnected in potentially explosive areas.
5. If the device is damaged, subject to an impermissible load, stored incorrectly, or malfunctions, it must be stopped and immediately removed from the Ex area.
6. The device is not suitable for installation in zone 22 (potentially dust-explosive areas).
7. If you still intend to use the device in zone 22, you must install it in a housing according to IEC/EN 60079-31 and adhere to the maximum surface temperatures.
8. Connection to the intrinsically safe circuit in areas with a danger of dust explosions (zone 20, 21, or 22) is only permitted if the equipment connected to this circuit is approved for this zone (e.g., category 1D, 2D, or 3D).
