☐ Run the oil pump to verify pump can provide
18 to 22 psid (124.1 to 151.7 kPaD) net
pressure.
☐ Verify and record control parameters.
☐ Verify all control interlocks are installed and
properly functioning.
☐ Set AFD grounding jumpers (PE-A for MOV
and PEB for Common Mode) for power
distribution grounding:
☐
Both jumpers “Connected” for Solidly
Grounded System (Center Ground Wye).
☐ Both jumpers “Disconnected” for Non
Solidly Grounded System (Any Delta,
High Impedance Ground, or
Ungrounded Wye).
N No otte e:: Refer to AFD-SVG002*-EN for more
information.
☐ Dry run starter (non-Adaptive Frequency ™
Drive [AFD]).
