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 90
°
C copper wire. See the appropriate column in Table E or
Table F. Wire sizes are based on using the specified breakers.
4.
Wire ampacities are chosen from Table 310---16 of the NEC. Wire is 90
°
C specification.
5.
The bypass feed into this equipment utilizes three or four wires. The rectifier feed into this
equipment utilizes 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.
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.
