NOTE: Callout letters A, B, C, and D map to drawing 164201535 ---4, sheets 1 of 5, 3 of 5, 4 of 5, and 5 of 5.

Read and understand the following notes while planning and performing the installation:

1.Refer to national and local electrical codes for acceptable external wiring practices.

2.Material and labor for external wiring requirements are to be provided by designated personnel.

3.For external wiring, use 90G C copper wire. See the appropriate information in Table E through Table H. Wire sizes are based on using the specified breakers.

4.Wire ampacities are chosen from Table 310---16 of the NEC. Wire is 90GC specification.

5.The bypass feed into this equipment uses three or four wires. The rectifier feed into this equipment uses three wires. The phases must be symmetrical about ground (i.e., from a Wye source) for proper equipment operation. If the load requires a neutral, a bypass source neutral must be provided. Do not bond the neutral to ground.

6.The UPS cabinet is shipped with a debris shield covering the ventilation grill on top of the unit. Do not remove the debris shield until installation is complete. However, remove shield before operating the UPS. Once the debris shield is removed, do not place objects on ventilation grill.

7.Refer to Section I of this manual for installation instructions.
