Replacing the Fuse (only for SPS
1525/1540 PFC)
If it is no longer possible to switch on the mains power supply, the mains fuse has
probably tripped.
Proceed as follows to replace the mains fuse:
• Switch off the mains power supply and remove all
the connection and power cables.
• Use a suitable screwdriver for slotted screws to prise
out the fuse holder on the rear of the device.
• Replace the defective fuse with a new fine-wire fuse
(5 x 20 mm) of the same type and rated current,
which are as follows:
- SPS 1525 PFC: F 3.15 A / 250 V (fast blowing)
- SPS 1540 PFC: F 5 A / 250 V
(fast blowing)
• Press the fuse-link back into the fuse holder until it
snaps in properly.
