Precharge and mains synchronisation (X21) for size 5 and
size 6A
The DC link is precharged via terminal X21/L1,L2,L3 (Figure 3.15, p. 38). At a defined
DC link voltage the contact of the internal relay on terminal X21/HREL is closed. The
mains contactor closes and switches the supply system to terminal X12/ L1,L2,L3. The
Power Supply Unit is synchronised with the mains via terminal X21/L1,L2,L3. Technical
data of mains contactor see section A.11, p. 73.
ATTENTION!
The cable must be protected by a circuit-breaker. Ensure the correct phase
angle of the conductors during installation (Figure 3.15, p. 38). Technical
data of circuit-breaker see A.12, p. 73.
