Replacing the fuse

About this topic

This topic describes how to replace the main fuse in the BenchCel Microplate Handler.

Before you begin

 

CAUTION A blown fuse can indicate more serious problems. If the new fuse blows after replacement, contact Automation Solutions Technical Support.

 

CAUTION Using an incorrect fuse can damage the BenchCel Microplate Handler.

Use only the specified fuse type: 5 A, 250 V, 5 mm x 20 mm, fast acting.

You can order fuses from Agilent Technologies.

 

 

Procedure

To replace the fuse in the power switch:

1	Shut down the BenchCel Microplate Handler, and unplug the power cable from the rear panel connector.

2	At the rear panel power switch enclosure, use a small flat-head screwdriver (2.5 mm) to pry open the tab on the fuse enclosure and open the enclosure cover.

3	At the top of the enclosure, insert the screwdriver head in the notch to dislodge the red fuse cartridge. Slide the fuse cartridge all the way out of the enclosure.

4	Replace the fuse or fuses for the type of system you are using:

•	115 V power. While maintaining the fuse cartridge orientation relative to the enclosure, replace the fuse on the right side of the cartridge. The cartridge might also contain a second fuse as a spare.

•	230 V power. Inspect the fuses on each side of the cartridge, and then replace the suspect fuse.

For 115 V power, ensure the fuse is properly installed in the correct side of the cartridge. Otherwise, the device might not turn on.
For 230 V power, ensure two fuses are installed in the cartridge.

 

5	Slide the fuse cartridge back into the fuse enclosure.

6	Press the enclosure cover securely into the closed position.

7	Plug in the power cable at the rear panel connector, and then start up the BenchCel Microplate Handler.
