Important Safety Instructions

Wiring Considerations
All wiring and branch circuit protection should follow the current edition of the American National Standards Institute (ANSI) approved National Fire Protection Association’s (NFPA) National Electrical Code (NEC), and applicable local codes. For operation in countries where the NEC is not recognized, follow applicable codes.

Electrical Connections Location Diagram
Electrical connections are made using separately ordered cable assemblies. One end of these cable assemblies contains a mating plug to the connector located on the bottom panel of the rectifier. Refer to Figure 4.1 for an electrical connection location diagram.

Figure: Electrical Connection Location Diagram
NOTE! The rectifier battery port may be used as a Load 4 port. Refer to “Operation in a Batteryless Installation” on page 57.

Rectifier Ground Connection

General
For grounding requirements, refer to the current edition of the American National Standards Institute (ANSI) approved National Fire Protection Association’s (NFPA) National Electrical Code (NEC), applicable local codes, and your specific site requirements.

Positive Grounding
As default, the power system is positive grounded. The Return (+) Bar of the power system is factory connected to the chassis PE terminal. If customer chooses to float the DC bus, perform the following procedure.

Procedure

1. Refer to “Opening / Closing the Front Access Panel” on page 62, and open the rectifier enclosure front access panel.
2. Locate the cable connected to the Return (+) Bar that is secured to the chassis PE terminal shown in Figure 4.2. Remove the cable from the chassis PE terminal and insulate and tie back the unconnected end.
3. Refer to “Opening / Closing the Front Access Panel” on page 62, and close the rectifier enclosure front access panel.
