Replacing the Fuse
For additional fuses, contact Major Science co. ltd.
To replace the fuse:
1. Turn off the main power switch on the rear of MS 250V or MS 300V Power
Supply and detach the power cord from the rear of MS 250V or MS 300V
Power Supply.
2. Open the fuse compartment located inside the Power Entry Module by
inserting a small flat blade screwdriver into the slot below the ON/OFF
switch. Turn the screwdriver to gently pry open the fuse compartment.
Note: The fuse compartment will not open with the power cord in place.
3. Pull the fuse holder out of the compartment and inspect the fuse. If the fuse
is burned or there is a break in the fuse element, replace the fuse with an
identical type of fuse (2A/250V~) as provided in the fuse holder (see figure
below).
4. Place the fuse holder back into the compartment.
5. Snap the cover closed.
