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 , 3-wire + ground.
-
Alternate AC Input: 3 , 4-wire + ground.
-
AC Output: 3 , 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 1.67 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.
11. Cable sizing calculations based on the following assumptions:
-
Minimum size is smallest size based on ampacity at 30 C.
-
No more than three current carrying conductors per conduit.
-
Neutral sized for 2 X phase current.
-
Temperature rating of copper conductors/terminals: 75 C.
-
Reference: 2005 NEC Handbook, Table 310.16.
NOTE: 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.
