4.10.2 Power supply
Mains supply
Operate only drive controllers with the same power supply voltage as part of
Quick DC-Link.
DANGER!
Device damage!
If single-phase and three-phase drive controllers are connected, the single-
phase drive controllers will be damaged.
Connect either all one-phase or else all three-phase drive controllers.
Note also the following rules:
• All single-phase drive controllers must be connected to the same external
conductor.
• All three-phase drive controllers must be connected to the same mains
power supply.
Special features for a connection with drive controllers size 3
• AC supply
If a Quick DC-Link consists of drive controllers of sizes 0, 1, 2 and 3, only
those of size three may be supplied with power. The others must be
supplied exclusively with DC voltage.
•Number
The maximum number of size 3 drive controllers you can connect is 3.
• Power choke
A power choke of type TEP4010-2US00 must be installed for each size 3
drive controller supplied with power (see 4.12.1 Power choke).
NOTICE
Material damage!
If the EMC limit values are exceeded while a DC link connection is in operation,
take suitable measures to maintain electromagnetic compatibility.
Always route the compound DC link connections as short as possible. If they
are longer than 30 cm, they must be shielded.
Protection against failure of a drive controller
NOTICE
Danger of device damage!
The failure of a drive controller in the DC link can cause damage to other drive
controllers. For this reason, a failure must initiate the separation of the
complete Quick DC-link system from the network.
Note in this regard the wiring and parameterization of relay 1 in 7.3.9 X30:
