Important Notes:
1. CABLE ACCESS – Top only.
2. Maximum Current required at Primary AC Input based on full
load output and maximum battery charging current.
3. Output load conductors are to be installed in separate
conduit from input conductors.
4. Control wires and power wires are to be installed in separate
conduits.
5. Recommended AC input and output overcurrent protection
based on continuous full load current per NEC.
6. Wiring shall comply with all applicable national and local
electrical codes.
7. Grounding conductors to be sized per NEC Article 250-122.
Neutral conductors to be sized per NEC Article 310.15.
-Primary AC Input: 3φ, 3-wire + ground.
-Alternate AC Input: 3φ, 4-wire + ground.
-AC Output: 3φ, 4-wire + ground.
-DC Input: 2-wire (Positive/Negative) + ground.
8. Nominal battery voltage based on the use of VRLA type
batteries (2.0 volts/cell nominal).
9. Maximum battery discharge current based on lowest
permissible discharge voltage of 1.67 VPC.
10.DC wires should be sized to allow not more than a 2-volt
drop at maximum discharge current.
11.Weights do not include batteries or other auxiliary equipment
external to the UPS.
12. Cable sizing calculations based on the following assumptions:
- Minimum size is smallest size based on ampacity at 30 °C.
- Maximum size cable is based on cable bend radius
limitations at the UPS terminals.
- Neutral sized for 2X phase current.
- Not more than 3 current-carrying conductors installed in
conduit in ambient temperature of 30 °C.
- 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.
13. Ratings of wires and overcurrent devices are suggested
minimums. Consult with a registered Professional Engineer
within your local area for proper size selections.
