Replacing Fuses
General
The fuses should be checked if the power is connected to SPS311, but
the ‘Standby’ LED on the Front Panel remains blank. There are three
user-replaceable fuses in the System, two in connection with the AC
power inlet and one in the DC Power Supply MWP312.
Replacing AC Power Inlet Fuses
In the connector panel there is a fuse holder in connection with the AC
power inlet. To replace the fuses:
1. Open the two adjacent fuse holders using a large screwdriver or
a coin. See Figure 8.
