Group I
See the figure above for wiring of RTDs to the URTD inputs. Use #18 AWG, three-
conductor shielded cable. Note the connection rules in the figure. When making
connections to a two-lead RTD, connect two of the cable conductors to one of the RTD
leads as shown. Make this connection as close to the transformer as possible. Connect
the third cable conductor to the remaining RTD lead.
Connect the shield / drain wire to the Shield terminal as shown in the figure. The RTD
cable shield should be connected only at the URTD end, and insulated at the RTD end.
The RTDs themselves must not be grounded at the object to be protected.
Remember to set the URTDII module DIP switches according to the types of RTDs in each
of the channels (see I.L. IL02602013E).
