Important Notes:  
11. Sizing calculations based on the following assumptions:  
1. Maximum Current required at Primary AC Input based on full  
load output and maximum battery charging current.  
-
Not more than 3 current-carrying conductors installed in steel  
conduit in ambient temperature of 30 degrees C.  
-
-
Temperature rating of conductors and terminals: 90 deg. C.  
2. Output load conductors are to be installed in separate  
conduit from input conductors.  
Feeder distance calculations based on NEC Tables 8 and 9  
data, allowing for 2% AC voltage drop.  
3. Control wires and power wires are to be installed in separate  
conduits.  
-
Reference: 2002 NEC Handbook. Consult latest edition of  
applicable national and local codes for possible variations.  
4. Recommended AC input and output overcurrent protection  
based on continuous full load current per NEC.  
12. Ratings of wires and overcurrent devices are suggested  
minimums. Consult with a registered Professional Engineer  
within your local area for proper size selections.  
5. Wiring shall comply with all applicable national and local  
electrical codes.  
13. More than one Battery Cabinet will require a DC Junction box  
for all battery cabinet connections.  
6. Grounding conductors to be sized per NEC Article 250-122.  
Neutral conductors to be sized per NEC Article 310.15.  
- Primary AC Input: 3φ, 4-wire + ground.  
- Alternate AC Input: 3φ, 4-wire + ground.  
- AC Output: 3φ, 4-wire + ground.  
- DC Input: 2-wire (Positive/Negative) + ground.  
7. Nominal battery voltage based on the use of VRLA type  
batteries (2.0 volts/cell nominal).

Fax: (713) 896-5212  
8. Maximum battery discharge current based on lowest  
permissible discharge voltage of 1.6 VPC.  
9. DC wires should be sized to allow not more than a 2-volt  
drop at maximum discharge current.  
10. Weights do not include batteries or other auxiliary equipment  
external to the UPS.
