Power Connections

1.0 Power Connections
This section identifies system components and indicates how these
components are electrically interconnected.
Warning: The G50 and the G60 S are electrically isolated to protect the patient and operator
!
from shock hazards. Defeating the electrical isolation can cause serious injury or death. All
peripheral devices attached to the G50 or the G60 S must comply to IEC 60601-1 and must be
powered from the auxiliary outlets of the respective ultrasound system. Communications or sig-
nal circuits of the G50 or the G60 S that are connected to devices that are not powered from the
onboard outlets must be optically isolated from the unprotected device, to maintain the electri-
cal isolation of the G50 or the G60 S respectively.
Figure 3-1 employs the PC board designations (A03, A05, etc.) and acronyms
(SWRG, LNF, etc.) defined in Table 3-1. The descriptions from which the
acronyms are derived appear in column four of Table 3-1. See Figure 3-2 for
voltage connections. See "Power Module" (page 2-2) for a discussion of the
power module operation.
Warning: The G50 and the G60 S contain hazardous voltages that can range from 90 Vac to
!
264 Vac. These voltages can cause serious injury or death. Only authorized service personnel
are permitted to remove protective covers and access the energized components of this sys-
tem.

Warning: Installation of incorrect fuses in the G50 or the G60 S can cause equipment damage,
!
fire, serious injury, or death. Replace fuses only with the same current value and fuse type sup-
plied by the factory and listed in Table 1-8. See "Spare Parts" (page C-1). See "Replacing the
OEM Outlet Fuse" (page 4-50).
