I-ADAP - Instruction for exchanging UWE against XU1-E Preparations General information For an easy exchange of earth fault voltage relay UWE of analogue design for the new digital earth fault voltage relay XU1-E, adapter type I-ADAP can be used. All necessary cables for connection of the XU1-E are provided at the adapter socket. Before exchanging the relays, the following has to be done: Output relay contacts Supervision relay type UWE is provided with two trip contacts (1 NO, 1NC). The XU1-E can realize both contacts of this relay. • The XU1-E has to be applied to the DIN rail of the adapter socket. • Connection terminals of the I-ADAP must point downwards. • The relevant cables have to be connected according to the connection diagram. • All cables which are not needed have to be removed. • Exchange of the relays in the switchboard has to be done as explained in the general exchange instructions (TB ADAP-S-E).
