Even if that weren't the case, it isn't the responsibility of the UPS to check the polarity, that's up to the property owner to take care of. |

Schuko plug has no markings and nothing really prevents you from plugging the cord the "wrong" way. |

Does everything have a polarity indicator? I'm kind of surprised that the Schuko plug has not been updated by now to at least have a polarity marking on it, a notch could be added easily enough to make polarized plugs while still allowing the old non-polarized plugs to be inserted. |

It's a bit of a loophole for IEC connectors. In the UK and in some other European countries, our plugs ensure polarisation so most IEC connectors use single-pole switches. |
