IREMARKSI
(1) One octave marked
*
indicates a change from the initial frequency to double or half
frequency. For example, any of the changes from 10Hz to 20 Hz, from 20 Hz to 40 Hz, from
40 Hz to 20 Hz, and 20 Hz to 10Hz are referred to as one octave.
(2) Since a varistor is provided between AC and LG, do not apply a voltage of 400 V or higher
between AC and LG.
(3) Disconnect grounding of FG and LG before applying the maximum allowable voltage to the
A66PC. 00 not connect leads to FG and LG when applying the maximum allowable voltage
since they are shorted in the module.
