Figure 16 SuperStack II RPS Power Supply Socket and Fuse
The PathBuilder S330/S310 automatically adjusts to the supply voltage. The fuse is
suitable for both 110V AC and 220-240V AC operations.
To change the fuse, follow these steps:
1 Turn of the power and unplug the unit.
CAUTION: Ensure that the power cord is disconnected before opening the fuse
holder cover.
2 Release the fuse holder by gently levering a small screwdriver under the fuse
holder catch. Use only 2A anti-surge type fuses of the same type and manufacture
as the original.
3 Remove the old fuse and replace it with a new one.
4 Close the fuse holder.
Step 4: Connect I/O
Cabling
