Changing the Fuses
WARNING! Electrical shock hazard. Disconnect the power cord before changing the fuses.
WARNING! For continued fire protection and correct system functioning, replace fuses only
with exact part number.
To change the plate handler fuses:
1. Verify the plate handler power switch is OFF and the power cord is unplugged from the
instrument.
2. Using a small flat-blade screwdriver at the top of the fuse housing, gently pry the fuse
housing (Figure 24) out of the power entry port.
3. Remove the two 2.5 A fuses.
4. Replace both fuses with fuses with the same part number.
5. Confirm that the fuses are seated securely in the fuse housing.
6. Snap the fuse housing back into the power entry port.
Power Outage
If a power outage occurs during operation of the CFX Automation System II, the grippers
will open and the plate will drop when the power is restored. If you routinely operate the CFX
Automation System II overnight or with valuable samples, consider using a 900 W (or greater)
uninterruptable power supply (UPS) to each connected instrument to provide a backup power
source for the CFX Automation System II, the CFX System(s), and the computer.
