DANGER!
Adhere to the “Important Safety Instructions” presented at the front of this document.
5.2
Wiring Considerations
All wiring should follow the current edition of the American National Standards Institute (ANSI) approved National Fire Protection
Association's (NFPA) National Electrical Code (NEC), and applicable local codes. For operation in countries where the NEC is not
recognized, follow applicable codes.
For wire size, crimp lug, and general wiring recommendations; refer to System Application Guide SAG588820400100,
SAG588820400150, SAG588820400200.
5.3
Access Covers
You may remove the front access cover(s) from the battery rack system to facilitate wiring and battery installation. When electrical
connections and battery installation are complete, reinstall all covers that were removed before operating the battery rack system.

Battery Rack Box Framework Grounding Connection (Frame Ground)
The battery rack box framework must be properly grounded.
For grounding requirements, refer to the current edition of the American National Standards Institute (ANSI) approved National Fire
Protection Association's (NFPA) National Electrical Code (NEC), applicable local codes, and your specific site requirements.
A customer's grounding network lead can be attached to the top of each battery rack box framework. Provision is made for installing
a lead with a two-hole lug that has 1/4" bolt clearance holes on 5/8" centers. Refer to Figure 5.1 for locations. When using 1/4-inch
hardware, recommended torque is 84 in-lbs when a standard flat washer and lock washer are used.
Note!
Remove any tape from hole locations before installing lug.
