    The sealable cover can be used to secure the actuators (rotary buttons and sliding switches) of the monitoring relays against unauthorized or unintentional manipulation. Siemens also offers a sealable membrane (3TK2820-0AA00) with a width of 22.5 mm for securing the monitoring relays. The sealable membrane is affixed to the front of the device and secures rotary buttons and sliding switches against unintentional operation.

    For this reason, the output relays are switched to the work position when the supply voltage is present. After completion of the initialization phase, a permanent self-test takes place without interrupting the monitoring function. 3UG4 / 3RR2 monitoring relays Manual, 05/2016, NEB927043002000/RS-AC/004…
