Note:

1. The base-up output with a 0-mA temperature controller output (i.e. the temperature controller is OFF) differs from that with a 4-mA

temperature controller output. Refer the 

Characteristics data on page 67.

2. When ordering, make sure that the rated voltage is 200/230 VAC because the 200/220-VAC G3PX exists as well.
