Important Notes:
1. Maximum input current is limited to 108% 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 215.3.
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, 3-wire + ground.
-
AC Output: 3, 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 method:
- Base cable ampacity is determined by 75
values in 2014 NEC Table 310.15(B)(16).
- Cable ampacity is derated for 40
Temperature per 2014 NEC Table 310.15(B)(2)(a).
- Cable ampacity is further derated for maximum possible of
conductors in Trade Size 4" EMT conduit per quantities shown in
2014 NEC Table C.1 and factors shown in Table 310.15(B)(3)(a).
- Cable meets bend radius limitations at the UPS terminals.
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.
13. Overcurrent protection devices rated at 1200AT and above are
assumed to be rated for 100% continuous operation.
