Replacing the fuse

About this topic

This topic describes how to replace the main fuse in the Vertical Pipetting Station.

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 Vertical Pipetting Station.

Use only the specified fuse type: 5 A, 250 V, 0.25 × 1.25 in (6.35 x 31.75 mm), fast acting.

You can order fuses from Agilent Technologies.

 

 

Procedure

To replace the fuse in the power switch:

1	Shut down the Vertical Pipetting Station, 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 at the top of the enclosure and open the enclosure cover.

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.

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 Vertical Pipetting Station.
