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 reasons, 
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.

Replacement of G32X-A20 Power 
Device Cartridge

Use the special tool (provided) to extract the Cartridge for 
replacement with a new one.

Extraction

Follow the procedures below to dismount the Power Device 
Cartridge from the G3PX.

1. Switch off the power.

2. Remove the terminal cover.

3. Hook the tool on the indented portions of the Power Device 

Cartridge as shown in the illustration below and pull up the Power 
Device Cartridge vertically.

Mounting

The procedures for mounting the Power Device Cartridge are as 
follows:

1. Apply silicone grease (provided with the G32X-A) to the entire 

surface of the heat sink.

2. Make sure there is no dust or pieces of wire on the heat sinks of 

the G32X-A or the G3PX.

3. Insert the Cartridge into the opening of the G3PX so that the 

letters on the Cartridge and those on the G3PX are in the same 
direction and sides A and B are even.

4. Attach the terminal cover.

5. Switch on the power and check the G3PX to be sure it works 

properly.

G32X-A40/60

The G32X-A40 and G32X-A60 are secured with screws.

Extraction

The procedures for dismounting the Power Device Cartridge are as 
follows:

1. Switch off the G3PX.

2. Remove the terminal cover.

3. Be sure to turn off the G3PX and loosen the screws located in the 

upper center and lower center. These screws are connected to 
terminals 1 and 2.
