SIMOVERT MASTERDRIVES
The purpose of the DC link bus module is to supply the connected
inverters with the generated direct voltage.
Bar Designation
3 PE3
2 D / L-
1 C / L+
Connectable cross-section: "Electro-plated copper" 3x10 mm, rounded
off according to DIN 46433.
Bar 1 is at the front when installed.
Table 7-2 DC link bus module
The connection for the external braking resistor and the pre-charging of
the capacitor module is provided on the top of the unit.
Terminal

H
D´
Connectable cross-section: 4 mm² (AWG 10)
Terminal D' is at the front when installed.
Table 7-3 Connection of the braking resistor and pre-charging of the capacitor
module
The connector must be firmly screwed onto the housing to provide a
reliable connection.
The thermostatic switch of the braking resistor must be integrated in the
de-energization circuit of the main contactor.
♦ 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!
