REX615 Operation Manual
  • Preferably, disconnect the binary input connector from the binary input cards.
  • Check all the connected signals so that both the input level and the polarity are in accordance with the protection relay specifications.
CAUTION: Do not use AC voltage. Binary inputs are rated for DC voltage only.
