Note:

 

 

 

1.

The auxiliary cables of the battery must be screened and double insulated.

 

2.

The screen is connected to the earth of the battery cabinet or supporting rack.

 

3.

Use multiple-core shielded cables with a section of 0.5 to 1 mm2.

 

4.

Connect the cables with the fast-on 6.3*0.8 mm terminals (female)

Connect the BCB control and temperature compensation cables between the UPS auxiliary terminal block X3 and BCB control board. For details, refer to Figure 6-5. These cable must be shielded, shield should be connected at protective earth of battery cabinet or battery breaker, not of UPS.

Note

If battery temperature compensation is needed, this function must be activated by the commissioning engineer.

3.4 Connecting Main Cabinet And Side Cabinet

The 300kVA UPS (12-pulse rectifier) and 400kVA UPS comprise a main cabinet and a side cabinet.. In installation, you need to make electrical connection between the main cabinet and side cabinet.

3.4.1 Connecting Power Cables

The power cable connections between the main cabinet and side cabinet of the 300kVA UPS (12-pulse rectifier) and 400kVA UPS are shown in Figure 3-9 to Figure 3-11. The installation engineer should make cable connection in strict accordance with these figures.
