Notes for Tables A---2, A---3, and A---4:
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. Power wiring size recommendation is copper wire rated at 75_C for Powerware
9315 models 40 through 300 and 90_C the Powerware 9315 400 and 500. If the
wire is run in ambient temperature higher than 30_C, larger size and/or higher
temperature wire is necessary.
4. The output for the UPS is a separately derived source. Output neutral is bonded to
equipment ground through the main bonding jumper. Refer to NEC Article 250 and
local codes for proper grounding practices.
