TOSHIBA
4200FA UPS
Installation Planning Guide for 15-80kVA UPS
Standard System: 208/120V Input, 208/120V Output
Rev. 1.03 Page 2 of 2 4200FA-IPG-208v
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.
- 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 include internal batteries.
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.
