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withdrawn).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
connection X7!
