NOTE: For screws with multiple tightening means, the largest torque value associ-
ated with the conductor size shall be marked. Slot length shall be measured at the
bottom of the slot.

DANGER
. This equipment does not provide isolation. Separate isolating means required. Isolation devices can
take several forms with the most simple being an appropriately sized disconnect switch and contactor pair utiliz-
ing the Inverter ‘Shunt Trip’ controls, or an appropriately sized and protected vacuum circuit breaker also capa-
ble of remote operation from the inverter ‘Shunt Trip’ controls.
WARNING
: Primary power source overcurrent protection is required. For disconnect switch and contactor pairs,
the components must be sized to accommodate the following fuse size ratings per chart below: (this also in-
cludes the table requirement of the list)
4160 Volt 260 Amp VFD; 300E 5500V fuse Mersen A055F2DORO-300E or equiv.
4160 Volt 300 Amp VFD; 350E 5500V fuse Mersen A055F2DORO-350E or equiv.
This unit provides electronic motor overload protection, refer to pages 77-79 for setup and operational details.
Grounding of the Inverter System
: Install ground connections for the inverter system (transformer rectifier
converter and inverter) and the motor by following the correct specifications to ensure safe and accurate opera-
tion. Using the inverter and the motor without the specified grounding connections may result in electric shock
and damage to the equipment. This shall include all input, output, and DC shielded power cable connection
grounds as applicable per installation.
