IMPORTANT SAFETY INSTRUCTIONS

Danger: Adhere to the “Important Safety Instructions” presented at the front of this document.

WIRING CONSIDERATIONS

All AC input and 400V DC output wiring, branch circuit protection, and grounding 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.

For wire size, branch circuit protection, crimp lug, and general wiring recommendations; refer to System Application Guide SAG584000300.

TORQUE

Torque all connections as specified in the illustrations presented in this chapter.

OUTPUT GROUND CONFIGURATIONS

These instructions apply both to the High Resistance Midpoint Grounded (HRMG) and Negative Pole Grounded (NPG) configurations. Ensure you follow the proper procedures for the configuration you have. Refer to the part number on your equipment. The table on the front cover of this document lists the various equipment part numbers and the configuration they apply to.

CABLE ROUTING

When System is Furnished in a Factory Provided IT Rack (List R1, R2)

If the system is furnished in a factory provided IT rack, connections between the system’s sub-racks and also to the IT rack ground bar are factory made. The electrical connections the customer is required to make are the following. Refer to Figure 3-1on the next page for a cable routing diagram.
