E)External Battery Supply

Please refer to the following when installing and maintaining batteries:

1.The customer shall refer to the battery manufacturer's installation manual for battery installation and maintenance instructions.

2.The maximum permitted fault current from the remote battery supply, and the DC voltage rating of the battery supply over-current protective device are shown in Table 3.4.

3.3Procedure for Cable Connections *

i.Confirm the capacity of the UPS being installed. Identify the input/output power terminal blocks as shown in the appropriate Figures 3.1-a, b through 3.2-a, b.

ii.Connect the grounding conductor from the input service entrance to the UPS ground bar.

*Wire per local and/or national code.

iii.Two (2) sources feeding the UPS:

(1)Connect the converter input power cables from the input service entrance to the converter input power terminals, identified as A, B, C in Figures 3.2-a, b. Input cables must be sized for an ampere rating larger than the maximum input drawn by the converter. (Refer to equipment nameplate for current ratings.) Refer to Table 3.5 for recommended cable sizes.

(2)Confirm that an external bypass input circuit breaker (MCCB) is installed (refer to WARNING 2, page 1-2). Connect the bypass input power cables from the input service entrance to the bypass input power terminals, identified as A40, B40, and C40 in Figures 3.2-a, b. Bypass input cables must be sized for an ampere rating larger than the maximum output current capacity of the UPS. Refer to Table 3.5 for recommended cable sizes.

(3)Referring to Figures 3.2-a, b, connect UPS load terminals A50, B50, C50 and N50 to the load distribution panel. Refer to Table 3.5 for cable sizes.

(4)Connect the external signal terminal block as desired. Refer to section 2.5 and Figure

2.15for functional description. 12 AWG, or less, shielded conductor is recommended.
