5-11-1-3 Fuses on Rear Panel (CPN6)
F1: The main Input voltage is fused by a magnetic Circuit breaker (Rated current 16A) built in the Main
Power switch labelled F1
F2:The AC Output voltage (115/230V) is fused by F2 (magnetic Circuit breaker 2.5/5A)
F3, F4, F5, F6: are the fuses for the input voltage for the switching power supplies generating the DC-
Supply voltage for the Secondary power supply inside GEF-Module
5-11-1-4 Fuses inside CPN6
F1 on CCF board: fuses the surge current limiter circuit.
NOTE: If this fuse is blown, the NTC (limiting the surge current will remain hot during system operation and if
the system is switched off/on within a few seconds the surge current could be to high.
Because of this reason Fuse F1 on CPN Rear Panel or the Hospital circuit fuse could be blown.
