Read and understand the following notes while planning your 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 requirements, including the minimum AWG size of external wiring, see

the appropriate column in TablesA throuigh C . Thepo werwiring for this equipmentis

rated at 90˚C.

4. Critical load power to be run in separate conduits, busways, or cabletrays and sufficiently

separated from source power.

5. System to be grounded to single point local or utility ground.
