Protective measures

It is very important that any intervention in the equipment will start with disconnecting it
from the power supply with the main circuit-breaker. Before removing or inserting any of
the printed circuit board, switch of the equipment. To prevent accidental triggering of high
voltage and radiation, set the switch S2 (SS) on p.c. board D702 to "OFF" (lower position,
no triggering of the SS relay).
If the system is only switched off at the control panel or with
S2/D711, line voltage will still be present at the generator line con-
nection, line filter Z1, Z2, transformer T1, transformer T10 and p.c.
board D711 (see wiring diagram).
Life-threatening electric shock hazard exists.
Disconnect mains cable and comply with the information on this
page.
After shut-down of the system, there may still be 380 V DC
present on the intermediate circuit.
Life-threatening electric shock hazard exists.
The voltage level will be indicated by LED V24 on PC board D710.
The voltage will drop to less than 30 V within about 3 minutes, the
LED goes out at about 30 V.
The p.c. boards contain electrostatic highly sensitive compo-
nents.
If not regarded, the components could be damaged.
Use ESD-equipment, ground prior to making contact and place
the components on a conductive surface.
The edges of the metal curtain of the stand are very sharp.
They may cause severe injury.
Apply the protective strips as mentioned in section "Protective
strips for the metal curtain" on page 3 - 5 after removing the cov-
ers from the stand. Remove the protective strips only when the
covers are to be mounted or when vertical adjustment of the
swivel-arm system is necessary.
