DC+, DC-: DC link voltage
(1) DBR+ and DBR-: Connection of external braking resistor
(2) AUX1, AUX2: only with C3H1xxV4 external supply (AC) for device ventilator L, N
All
shields must be connected via a cable joint to the cable feed through plate.
Braking resistor and cable must be shielded if they are not installed in a control
cabinet.
The standard connection clamps of C3H090V4 and C3H1xxV4 are
