v Section 1.4.3 “Accessories”
A
Use only original replacement fuses. If other fuses are used, this
will invalidate the warranty!
V The pcbs carry supply line voltages. Work on the circuitry must
therefore only be carried out while the equipment is completely
disconnected from the supply!
To avoid dangerous situations, follow the regulations for “Working
on live equipment“ (VDE 0100 Part 410).
