Table 7-13
Connection of precharging capacitor module
The connector has to be screwed firmly to the housing (providing
resistance to vibration and protecting against being inadvertently
withdrawn).
♦
During operation, the full DC link voltage is always present at the
terminals for pre-charging the capacitor module.
♦
During pre-charging, the charging current of all connected capacitor
modules flows via the terminals.
♦
For reasons of protection, cables with 4 mm
