3.3.2.1.2 Standard 90-260V AC Operation – Replace the Fuses
WARNING! DISCONNECT THE POWER SUPPLY BEFORE PROCEEDING!
CAUTION – FOR CONTINUED OPERATOR SAFETY, ALWAYS REPLACE THE
FUSES WITH THE CORRECT TYPE AND RATING.
The MBT-5000A uses two 20 mm slow-blow fuses – one each for line and neutral connections
(L1, L2 where appropriate). The fuses are located in the rear panel at the International
Electrotechnical Commission (IEC) AC power supply module (Figure 3-7). The fuses are
contained within a fuse holder that is press-fit into the body of the module.
To replace the AC fuses, do these steps:
•
First, unseat the fuse holder from the IEC power module.
Use the slot to pry the holder outward from the IEC power module.
o
Pull the holder straight out, and then swing the holder away from the module.
o
•
Then, remove and replace the fuses as needed.
Use T2.0A (2 Amp) fuses for standard operation.
o
•
Finally, re-seat the fuse holder in the IEC power module.
