Introduction - Siemens SONOLINE G50 Service Manual

Introduction

1.0 Introduction
The removal and installation (replacement) procedures included in this chapter
share several characteristics: The operating voltages and the weight of the
monitor represent specific hazards.
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: The weight of the G50 and the G60 S (130 kg; 287 lb) and the weight of the monitor
!
(18 kg; 40 lb) represent lifting hazards. The use of improper lifting methods or lifting in an awk-
ward manner can cause serious injury.
The US National Institute for Occupational Safety and Health publishes design guidelines that
indicate that items weighing greater than 15.9 kg (35 lb) must be lifted by two people or
mechanical lifting aids. Items weighing greater than 34 kg (75 lb) must be lifted only with
mechanical lifting equipment. The transport instructions for the G50 and the G60 S, when pack-
aged in its shipping container, are provided on the container. The G50 and the G60 S, once
removed from their shipping containers, are not designed to be lifted. Transport the G50 or the
G60 S by moving them on their casters.
At the time of the initial release of the G50 and the G60 S, it is likely that the
Spare Parts Catalog (SPC) located on the intranet will not have been
completed for these ultrasound systems. For this reason, interim spare parts
lists have been included in this manual: See "Spare Parts" (page C-1).
Some procedures overlap and duplicate the description of some tasks:
"Removing the Control Panel" (page 4-28) and "Removing the Keyboard"
(page 4-33) share the steps that describe the removal of the control panel.
The installation of a spare part employs the reverse sequence provided for the
disassembly and removal procedure.
!
Warning: An over-long fastener can penetrate underlying equipment during installation, caus-
!
ing damage to the equipment or the shorting of energized circuits. Shorted circuits, energized
at 90 Vac to 264 Vac, represent the potential for serious injury or death to the CSE, the user, or
the patient. Penetrated equipment can malfunction and cause erroneous exam results. When
removing fasteners (screws and bolts), during the disassembly of the G50 or the G60 S, care-
fully store these fasteners with the related component so that the correct fastener is easily
located for reinstallation. Before reinstalling a fastener, review the procedure to verify that the
proper fastener is used: Specifications for fasteners are included in the following procedures
and warnings are provided when the installation of an incorrect fastener represents a hazard.
Fastener specifications are provided in "Fastener Reference" (page H-1).

Caution: Some cables installed on the G50 or the G60 S use identical connec-
tors. Read the label attached to the cable and verify the label at the connector,
before connecting a cable.
Note: See "Fastener Reference" (page H-1) for examples of the types of fasten-
ers employed in the G50 and the G60 S.
