C´
Pre-charging for capacitor module
G
Braking resistor

Connectable cross-section: 4 mm² (AWG 10)
Terminal D’ is at the front when installed.
Table 7-4
Connection of the braking resistor and pre-charging of the capacitor
module
The motor cables must be dimensioned in accordance with VDE 298,
Part 2.
After installation of the connector, the shield of the motor cable must be
fixed to the shield plate through a large surface area.
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withdrawn).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 mm² Cu should be used at
connection X6!
Length of connecting cable between converter and external brake
resistor < 15 m.
