5. Normal operation
The specifications for the intended use according to EN 50348 apply. In addition the
operating manuals of the relevant electrostatic system must be complied with!
Operation of the system must only be carried out by a trained operating team. The per-
sonnel must be informed in reasonable intervals about the accident prevention regula-
tions and about the operation of the system.
CAUTION
The 400 V supply should only be disconnected if the high-voltage
was switched off beforehand.
Exception: Emergency Stop in hazardous situations.
CAUTION
In work in which parts connected with the high-voltage output can
be reached the following must be done:
The high-voltage must be switched off.
All high-voltage carrying parts must be discharged to a discharge
energy of less than 350 mJ
The 400 V supply must be safely disconnected and secured
against being switched on again.
The high-voltage carrying parts grounded with a suitable ground-
ing rod.
The high-voltage cascade and the high-voltage transformer are
enclosed in a housing with cooling ribs. Cooling ribs must be kept
clean so that they do not lose their function. If dirty they must be
cleaned with a suitable cleaning agent.
Fundamentally the regulations for normal operation of the HV generator must be ob-
served during maintenance and repair work of the surrounding system. Electrical sys-
tems under power must not be worked on.
5.1.
Safe switching off of the high-voltage before access
To guarantee safety before and during a release of the access to high-voltage carrying
components the following sequence must be complied with and also ensured through
technical actions:
1. Switch off the high-voltage via CAN command
2. Wait until "safely off" is reported via the feedback contact. This should be done
after 60s at the latest. In the interest of safety also this should be monitoring in
order to recognize if, for example, the system capacity changes.
3. Switch off the 400V supply
