External output Refer to *2
*1: When the communication module for bus connection (A9GT-BUSSU/A9GT-
BUS2SU/A9GT-QBUS2SU) is loaded, this value is equivalent to the input
max. apparent power value when the communication board is loaded.
*2: For external outputs please refer to the A985GOT/A975GOT/A970GOT/
A960GOT User’s Manual that is to be purchased separately.
Remarks
Note that the power is reset if an instantaneous power failure occurs.
However, if the instantaneous power failure is within 20ms when using 100
to 240VAC, or within 1ms when using 24VDC, the operation will be normal.
