7. The output of 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.
8. External overcurrent protection is not provided by this product, but is required by codes.
Refer to Table A through C for wiring requirements. If external overcurrent protection or an
output lockable disconnect is required, it is to be supplied by designated personnel.
9. Non-linear loads can create neutral currents that are greater than 100%. This product can
accommodate double-sized neutral terminations if needed.
