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creepages as per EN 61800-5-1 are no longer maintained.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.
