3. Connect the grounding conductor from the input service entrance to the UPS ground
bar.
4.
5. Two (2) sources feeding the UPS:
(1) Connect the rectifier input power cables from the input service entrance to the
rectifier input power terminals, identified as A, B, C in Figures 3.2-a~g. Input cables
must be sized for an ampere rating larger than the maximum input drawn by the
rectifier. (Refer to equipment nameplate for current ratings.) Confirm that an
external bypass input circuit breaker is installed (refer to WARNING 2, page 3).
Connect the bypass input power cables from the input service entrance to the
bypass input power terminals, identified as A40, B40, C40 and N40 in Figures
3.2-a~g. Bypass input cables must be sized for an ampere rating larger than the
maximum output current capacity of the UPS. Refer to Table 3.4 for recomended
cable sizes.
(2) Connect the external signal terminal block as desired. Refer to Section 2.4 and
Figure 2.15 for functional description. 14 AWG (2mm
2
), or less, shielded conductor
is recommended.
6. One (1) source feeding the UPS:
(1) Confirm that an external input circuit breaker sized to protect both the rectifier input
and the bypass line is installed. (Refer to equipment nameplate for current ratings.)
Connect the bypass input power cables from the input service entrance to the
bypass input power terminals, identified as A40, B40, C40 and N40 in Figures
3.2-a~g Input cables must be sized for an ampere rating larger than the maximum
current capacity of the UPS. Refer to Table 3.4 for recommended cable sizes.
(2) Using adequately sized conductors and referring to the appropriate figure identified
in Figures 3.2-a~g, jumper bypass terminals A40, B40, and C40 to rectifier input
power terminals A, B, and C respectively, as identified in Figures 3.2-a~g.
