AC Current and
Voltage Inputs
The relay is provided with terminal blocks for up to 12 ac currents and 6 phase-
to-neutral voltages.
Each of the current input circuits has polarity (•) marks.
A complete schematic of current and voltage circuits is shown, for details see
“AC Schematic Drawings” in Appendix I and “DC Schematic Drawings”
in Appendix J.
External Inputs
The relay contains 9 (3U) or 20 (4U) programmable external inputs.
Output Relay
Contacts
The relay has 14 (3U) or 21 (4U) programmable relay contacts.
Relay
Inoperative
Alarm Output
If the relay is in self check program or becomes inoperative, then the Relay In-
operative Alarm output contact closes and all tripping functions are blocked.
