52 Altivar 312 variable speed drives Wiring Diagrams ATV312H ppp M2 ATV312H ppp M3, ATV312H ppp N4, ATV312H ppp S6 Single-phase power supply Three-phase power supply (1) Line choke (single-phase or three-phase). (2) Detected fault relay contacts. Used for remote signalling of the drive status. (3) Connection of the common for the logic inputs depends on the position of the switch (see schemes below). Note: All terminals are located at the bottom of the drive. Install interference suppressors on all inductive circuits near the drive or connected on the same circuit, such as relays, contactors, solenoid valves, fluorescent lighting, etc. Compatible components (for a complete part number list, please refer to "Motor starter solutions - Control and protection components" catalog) Item no.
