11. Sizing calculations based on the following assumptions:

- 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.

- Feeder

distance

calculations based on NEC Tables 8 and 9

data, allowing for 2% AC voltage drop.

- Reference: 2002 NEC Handbook. Consult latest edition of

applicable national and local codes for possible variations.

12. Ratings of wires and overcurrent devices are suggested

minimums. Consult with a registered Professional Engineer
within your local area for proper size selections.

13. More than one Battery Cabinet will require a DC Junction box

for all battery cabinet connections.

Important Notes:

1. Maximum Current required at Primary AC Input based on full

load output and maximum battery charging current.

2. Output load conductors are to be installed in separate

conduit from input conductors.

3. Control wires and power wires are to be installed in separate

conduits.

4. Recommended AC input and output overcurrent protection

based on continuous full load current per NEC.

5. Wiring shall comply with all applicable national and local

electrical codes.

6. Grounding conductors to be sized per NEC Article 250-122.

Neutral conductors to be sized per NEC Article 310.15.

- Primary AC Input: 3

φ, 4-wire + ground.

- Alternate AC Input: 3

φ, 4-wire + ground.

- AC Output: 3

φ, 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).

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.
