REMU2A – Tie Line Unit

Note The “GND” position is used to connect PEMU circuits back-to-back on premises only, 1000 feet maximum (E&M lead wires must be crossed).

5.Insert the PEMU (component side facing right) into the appropriate slot and apply firm, even pressure to ensure proper mating of connectors.)

6.After installing, gently pull the PEMU outward. If the connectors are properly mated, a slight resistance is felt.
