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.

G3PX G3PX Replacement Parts G32X-A Power Device Cartridge The temperature indicator will be lit in red if the power element is damaged. If the power element is damaged due to overcurrent or other rea- sons, the power element and its peripheral parts can be replaced. The power element and its peripheral parts can be replaced without disconnecting the wires of the G3PX. - Page 14 G3PX G3PX 4. Loosen the screws on both corners. 3.
