Operation

7.1 Important Safety Instructions

CAUTION! Performing various steps in the following procedures may cause a service interruption and/or result in the
extension of alarms. Notify any appropriate personnel before starting these procedures. Also, notify personnel when these
procedures are completed.

7.2 Initial Startup Preparation

Ensure that all blocks (except the last one) in the Installation Acceptance Checklist on 2 have been checked.
•
Ensure that module mounting positions are filled by a rectifier module, solar converter module, -48 VDC to +24 VDC
converter module, or -48 VDC to -58 VDC converter module, and inverter module as required. It is acceptable for positions to
be left vacant.
•
Refer to the separate NCU User Manual supplied with your power system for complete controller operating information.
•
Refer to the configuration drawing (C-drawing) supplied with your power system documentation for factory settings of
adjustable parameters.

7.3 Initially Starting the System

Procedure
1. Apply battery power to the system by closing the external battery disconnect(s) or protective device(s) that supplies battery
power to the system, if furnished. Close the system's internal battery disconnect circuit breakers, if furnished.
2. Apply rectifier AC input power to the system by closing ALL external AC disconnects or protective devices that supply
rectifier AC power to the module mounting assemblies. Rectifiers, -48 VDC to +24 VDC converters or -48 VDC to
-58 VDC converters (if furnished), and inverters (if furnished) automatically start.
NOTE!
By default, the inverter runs in AC Mode. Refer to the NCU Instructions (UM1M830BNA) to change this mode, if
required.
3. Apply solar converter DC input power to the system (if required) by closing ALL external DC disconnects or protective
devices that supply solar converter DC power to the module mounting assemblies. Solar converters (if furnished)
automatically start. Close the system's internal solar converter input circuit breakers, if furnished.
NOTE!
After startup, verify that the controller is configured to the correct solar operating mode (disabled, rect-solar, solar).
Refer to "Configuring the Controller for Rect/Solar Mode when Solar Converters are Furnished" on page 165. The controller
will not recognize solar converters when the solar mode is disabled.
4. Open the distribution cabinet's front door.
5. Place each distribution circuit breaker (if furnished) to the ON position.
Place each circuit breaker located on the AC distribution shelf(s) to the ON position (if equipped with optional inverter
system).
