6 Safety informations for start-up
CAUTION
Before handling any boards, please make sure that your body is electrostatically discharged to protect
electronic components against high voltages caused by electrostatic charges. The simplest way of
doing this is to touch a conductive, grounded object (e.g. bare metal cabinet component immediately
beforehand).
PCBs must not be allowed to come into contact with highly insulating materials (e.g. plastic foil,
insulating table tops or clothing made of synthetic fibers).
PCBs may only be set down on electrically conducting surfaces.
WARNING
Hazardous voltages are present in this electrical equipment during operation. Non-observance
of the safety instructions can result in death, severe personal injury or substantial property
damage.
The converters must not be connected to a supply with earth-leakage circuit-breaker (VDE
0160, Section 6.5) since, in the event of a fault to frame or ground, the fault current may contain
a DC component that will either prevent or hinder a higher-level e.l.c.b. from tripping. In this
case, all loads connected to this e.l.c.b. have no protection either.
Only qualified personnel who are thoroughly familiar with all safety notices contained in the
operating instructions as well as erection, installation, operating and maintenance instructions
should be allowed to work on these devices.
The successful and safe operation of this equipment is dependent on careful transportation,
proper storage and installation as well as correct operation and maintenance.
The converter is at a hazardous voltage level even when the line contactor is open. Before
carrying out any maintenance or repair work, all converter power sources must be disconnected
and locked out.
These instructions do not claim to list all of the measures required to ensure safe and reliable
operation of the converter. For special applications, additional, supplementary information or
instructions might be required. If problems do occur and you feel in any way uncertain, please
contact your local Siemens office or representative.
The use of unauthorized parts in the repair of this converter and handling of the equipment by
unqualified personnel can give rise to hazardous conditions which may cause death, severe
personal injury or substantial property damage. All safety notices contained in this instruction
manual and attached to the converter itself must be carefully observed.
Please read the safety information given in Section 1 of this instruction manual.
