Note: Refer to Figure A – 3 on system one line diagram for the bold letter callout
locations.
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, use 90 o C copper wire. See the appropriate column in Tables A
and B. When wiring to an external battery cabinet, either 75 o C or 90 o C wiring may
be used.
4. Wire ampacities are chosen from Table 310-16 of the NEC.
5. A neutral feeder is required for both the main and bypass inputs to this system.
6. Refer to section 1 of this manual for installation instructions.
