4200FA XT 80kVA Installation and Operation Manual

APPENDIX A – Installation Planning Guide

Installation Planning Guide for 80kVA UPS

Standard Systems: 208/120V Wye, 208/380/480/600V Delta Input, 208/120V Output

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 and Table 310.16 (75 deg. C.Conductor).

Primary AC Input: 3

, 3-wire + ground.

AC Output: 3

, 4-wire + ground.

DC Input: 2-wire (Positive/Negative) + ground.

7. Power cable maximum size:

15/25/30kVA: #1 AWG

50kVA: 250 kcmil

80kVA: 500 kcmil, Battery Terminals – 600 kcmil

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 1.6 VPC.

10.

DC wires should be sized to allow not more than a 2-volt drop at maximum discharge current.

11. Weights include internal batteries.

12. 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: 75 deg. C.

Feeder distance calculations based on NEC Tables 8 and 9 data, allowing for 2% AC voltage drop.

Reference: 2008 NEC Handbook. 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.
