J 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.
Improve the heat radiation of the G3PX before replacing the Cartridge.
The temperature indicator will not be lit in red if the G3PX has overcurrent due to load short-circuiting or other reasons over a short time.
