Inquiry about the installed jumpers between PA/PO and PWR and +24vdc on the ATV61/71 drives
Altivar ATV61 and ATV71
IP20 ATV61 and ATV71 drives
Drives are shipped with factory jumpers should they be removed or not?
PO and PA jumpers normally should not be removed. In some cases a customer may remove the PO/PA jumpers and add a DC choke in its place.
PWR and +24vdc jumpers normally should not be removed. In some cases a customer might remove the jumper and add a normally closed dry contact for an e-stop circuit or a shutdown circuit.
