APPENDIX B. FUSE REPLACEMENT
In the event that the controller fails to power up when the power switch is turned on check
the line power fuse to see if it has blown. The fuse is located in the fuse holder on the power
entry module on the back of the controller. To remove the fuse holder first unplug the power
cord from the power entry module. This will reveal a slot just under the edge of the fuse
holder. Use a screwdriver to pry the holder straight out of the power entry module.
The fuse that is readily visible in the fuse holder when you take it out is the one that is
“active” when the holder is installed. A spare fuse is also stored within the fuse holder. It is
concealed in a compartment as shown in Figure B-2. To remove the spare fuse, press down
on the end of the compartment to push it out of the other end. The old fuse can serve as a
convenient tool for pushing the spare fuse compartment out. Replace the active fuse with
the spare and re-install the fuse holder and power cord. If the controller fails to power up
with the new fuse installed, call Sutter Instrument technical support personnel for
assistance.
