Wiring of 590 DC Cabinet

The Parker 590 DC Cabinet requires careful wiring of power, control, and earth connections following safety and EMC guidelines, with permanent earthing and screened control cables.Power ConnectionsMain Supply Terminals (L1, L2, L3): Connect directly to the incoming AC supply. Avoid series sequencing switches or contacts unless approved by Parker SSD Drives .DC Bus Terminals (F+, F-): Connect to the motor field and armature circuits as per the installation diagram. Ensure external fuses or MCBs protect the circuits according to the motor and drive ratings .Auxiliary Supply (D8/L): Connect directly to the auxiliary supply; no series contacts are allowed without consultation .Control WiringControl Terminals (A+, A-, D3, D4, D5, D6, D7): Use screened control cables with a minimum cross-section of 0.75 mm² (18 AWG) to comply with EMC requirements .Current Limit Connections: Adjust the MAIN CURR. LIMIT parameter via the control terminals. Removing B8 from C9 triggers a Program Stop (regenerative drives), and removing B9 from C9 triggers a Coast Stop .Grounding and EarthingPermanent Earthing: The drive must be permanently earthed using a protective conductor. A dirty earth rail connects to the external PE, and a clean earth rail connects directly to the dirty rail but is insulated from the mounting panel .Control Terminals: All control and signal terminals are SELV (double insulated) but must still be connected to the clean earth rail for EMC compliance .Safety PrecautionsAlways isolate all incoming supplies before working on the drive .Allow at least 10 minutes for capacitors to discharge to safe voltage levels (
