Notes on wiring
diagram
1. Install fuses according to these operating instructions.
2. Do not connect any additional consumers besides the regenerative power supply unit
behind the input contactor connected in the incoming cable.
3. Cable cross section according to applicable VDE regulations.
4. You can connect one or more drive controllers at this site (even with different power
ratings). Keep the DC connection cables
as short as possible
even when connect-
ing several drive controllers! Route the cables as closely as possible.
5. The option of an external "ON" or "RESET" takes place via terminal pairs X2:9 and
X2:10 as well as X2:11 and X2:12 (
→
section "Terminal assignment control terminal
strip X2"):
– X2:9 and X2:10: Isolated contact (short-term contacting)
– X2:11 and X2:12: Positive impulse (DC 12 - 24 V); can be implemented through
PLC control (terminal 11 +, terminal 12 –)
6. Select the size of the connected voltage supply using the voltage selection switch
prior to turning on the supply voltage
. (
→
following table).
There is also the risk of a defect in case of improper operation. The tolerance limit for
improper operation is set to a time of < 1 min (for cold units).
NOTICE
Non-compliance may result in a dangerous voltage increase during regeneration when
you disconnect the power supply; the presence of such a dangerous voltage may
cause irreparable damage to any additional consumers, drive controllers as well as the
regenerative power supply unit in the disconnected section!
Position of the voltage selection switch
Size of connected supply voltage
400 V
AC 380 V - AC 415 V ± 10 %
460 V
AC 440 V - AC 480 V ± 10 %
500 V
500V AC ± 10 %
NOTICE
• Make sure that the switch setting of the voltage selection switch corresponds to the
supply voltage prior to turning on the supply voltage. The unit will be destroyed if
the value is incorrect!
• The voltage selection switch is located in the device and can be set with the front
panel removed. The factory setting is AC 500 V. Deenergize the device before you
open it.
• The voltage selection switch may not be operated under voltage.
