4.7.5
Connection, mains 400/480 V AC (X12)
Note the following points:
y
Switching the mains power:
− In the event of excessively frequent switching of the precharging, the device
protects itself by means of high-impedance decoupling from the mains. After
a rest phase of a few minutes the device is ready to start once again.
y
TN system and TT system: operation is allowed:
− For device with phase conductor voltage 3 x 400 V AC, 3 x 460 V AC and 3
x 480 V AC if
5. The star point of the supply system is earthed and
6. The supply system is compliant with the maximum overvoltage category
III as per EN61800-5-1 with a system voltage (phase conductor
star
point) of max. 277 V.
y
IT system (isolated star point): operation is not allowed!
− If there is an earth fault the voltage is approx. twice as high. Clearances and
creepages as per EN 61800-5-1 are no longer maintained.
NOTe:
You will find further information on current carrying capacity, technical data
and ambient conditions in the appendix.
For connection diagrams for BG5, BG6a and BG7, see from chap. 4.3.3 and
following text
4.7.4
Precharging (X44) and mains synchronisation (X45) for
BG7
The regenerative unit is synchronised with the mains via the terminals X45/S1,S2,S3,SN.
The regenerative unit in the BG7 is pre-charged via the terminals X45/ P1, P2, P3. This
contact is disconnected again from the main after pre-charging by means of an auxiliary
contact on the mains contactor, see Figure 4.11.
NOTe:
The cable must be protected, see chap. A.10 and chap. A.12. During
installation pay attention to the correct conductor phase angle.

Caution!
Risk of injury or damage to the device due to incorrect operation!
•
Carelessness may result in minor injuries or damage.
For safety reasons, during operation the connection X44/3+4
must
be connected to SELV/
