Connectable cross-section: 4 mm² (AWG 10)
Terminal C' is at the front when installed.
Table 7-8 Connection of the braking resistor and pre-charging of the 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withdrawn).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 X6!
Length of connecting cable between converter and external brake
resistor < 15 m.
