Section II. Installation & Standby Circuit
power supply, and the operator must start or stop the inverter by using
the COM/FWD of the control terminal or Keyboard, in order to avoid
damage to the bridge rectifier.
※ Don’t connect A.C. input power to the output terminals U, V, W of the
frequency inverter.
※ In order to prevent unexpected accidents, earthing terminal E or
must be grounded to the earth securely (the grounding resistance
should be below 100Ω). The cable size should be greater than half of
below- mentioned corresponding cable size; otherwise current leakage
will happen possibly.
※ For wiring of main circuit, please refer to national rule.
※ Capacity of the motor should be equal to or smaller than that of the
inverter.
2-7. Standby circuit
When the fault or trip of the inverter may cause great loss or accident,
please add the standby circuit.
Note: confirm and test the running characteristic of the standby circuit, in
order to ensure the industrial phase and the converter phase are in the
same direction.

Section III. Operating keyboard
3-1. Options of internal keyboard and external keyboard.
PI7500 could display on both the internal keyboard and external
keyboard
But it could not be operated by the internal keyboard and external keyboard
simultaneously. And it could be shifted between these two keyboards by
JP3 on the control card.
The internal keyboard’s potentionmeter and external keyboard’s
potentionmeter could not be operated simultaneously, but it could be shifted
between these two potentionmeters by JP5 on the control card.
