14. Check the voltage across the terminals battery input plug DC distribution rack

using a DMM. Ensure that a reading of 48 volts DC is present. If so insert the

plug into the corresponding socket on the front of the DC distribution rack.

15. Repeat the above steps for battery 2 if required.

Note: If any faulty readings were recorded during the process, this would

indicate a damaged monobloc or battery strap. Investigate and replace the

faulty component.

7.3. Installation Summary of the BSPS

The following steps should be carried out when installing BSPS racks:

1. Verify that the circuit breakers of the load, battery and line input are

disconnected and the system is not connected to the line.

2. Connect the main unit to the battery and load via the Battery and Load terminals

on the rear panel.

3. Connect (if needed) the Extension and DC Distribution units.

Pay special

attention to the polarities of the wires and locations.

4. Insert a rectifier module into the main unit. All compartments are similar and

connected in parallel.

5. Use 16mm

(5 AWG) wires for the AC terminals. Minimum requirement is

8mm

(8 AWG)

6. AC source must be current limited (50A) using an external circuit breaker.

7. Plug the AC input cord into the AC source.

8. Turn on the Line circuit breaker, and verify that the system controller is

activated.

9. Insert the other rectifiers, and verify all green LED's on the panels are lit.

10. All parameters such as the output voltage are pre-defined in the factory.
