5.3.4 Startup after long downtimes
The high-voltage DC charger switches off automatically when it is not operated for a long
period of time (factory setting: 24 hours). In this case, you must carry out a warm start of
the high-voltage DC charger (see the “Warm start” section).
5.3.5 Self-test
The high-voltage DC charger runs a self-test as soon as you start it up. The message “
Self-
check
” and a progress bar appear on the LC display.
During the self-test, the product tests all electrical systems required for safety and proper
functioning. The self-test takes about 50 seconds.
While the self-test is ongoing, you can already control certain functions using the function
keys (see the “Using the LC display” section).
