Changing The Fuse(S) - Agilent Technologies 1200 Series User Manual

5 Troubleshooting and Error Handling

Changing the Fuse(s)

Fuses burn out occasionally and must be replaced. If the power indicator light
on the front of the unit does not light after switching ON the Well-plate
Handler, first check to see whether the power cord is securely seated in a
functioning power outlet and in the Well-plate Handler power cord receptacle
at the rear of the Well-plate Handler. If the power failed while the Well-plate
Handler was ON, check that the power cord is not loose or disconnected and
that power to the outlet is functioning properly. If these checks fail to remedy
the loss of power, follow the steps listed below to replace the fuses.
Spare fuses are shipped with Well-plate Handler. If you no longer have spare
fuses, you may obtain new ones from Agilent Technologies. The Well-plate
Handler uses the following fuses:
• U.S.: 1.5 amp, 0.25 x 1.25 inch
• Metric: 1.0-amp, 5.0 x 20 mm
Make sure the power to the Well-plate Handler is OFF and that the power cord is
