Important Notes:

1.Maximum input current is limited to 106% of the full-load input 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: 3φ, 3-wire + ground.

-Alternate AC Input: 3φ, 3-wire + ground.

-AC Output: 3φ, 3-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.

-Maximum size cable is based on cable bend radius limitations at the UPS terminals.

-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.

12.Ratings of wires and overcurrent devices are suggested minimums. Consult with a registered Professional Engineer within your local area for proper size selections.
