4. WIRING
GA7200 has been programmed to operate from the digital operator when shipped from the factory.
Therefore, just connecting the main circuit power enables drive operation.
Note: When external signals or external devices and digital operator are used, refer to Section 7,
“CONSTANTS/FUNCTION LIST”, in this manual.

5. DIGITAL OPERATOR PROGRAMMING
The following is an operation example for the digital operator keypad.
PRECAUTION
Before Power ON
 For the 460V class, 25HP (18.5kW, 34kVA) or larger inverter,
change the supply voltage selection tap of control transformer
to the same tap as input voltage. Refer to Installation Manual.
Before Operation
 Be sure to set input voltage in control constant Cn-01.
The initial value is 220 for 230V class
,
440 for 460V class.
