4. Two (2) sources feeding the UPS:
(1) Before connection of alternate source, ensure that input bus bar jumper is removed.
Connect the AC input power cables from the input service entrance to the AC input
power terminals, identified as A, B, C in Figure 5-1 through Figure 5-4. 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.) Confirm that an external
bypass input circuit breaker (MCCB) is installed (refer to WARNING 4, page 10).
Connect the bypass input power cables from the input service entrance to the bypass
input power terminals, identified as A40, B40 and C40 in through Figure 5-4. Bypass
input cables must be sized for an ampere rating larger than the maximum output current
capacity of the UPS. Refer to Table 5–4 for recommended cable sizes.
(2) Connect the external signal terminal block as needed. Refer to Section 4.4 and Figure
4-16 through Figure 4-19 for functional description. 14 AWG (2mm
conductor is recommended.
5. One (1) source feeding the UPS:
(1) Confirm that an external input circuit breaker sized to protect both the AC 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 and C40 in through Figure 5-4. Input cables must be
sized for an ampere rating larger than the maximum current capacity of the UPS. Refer
to Table 5–4 for recommended cable sizes.
(2) Using adequately sized conductors and referring to the appropriate figure identified in
Figure 5-1 through Figure 5-4, connect jumper bypass terminals A40, B40, C40 to AC
input power terminals A, B, C as identified in Figure 5-1 through Figure 5-4.
(3) Connect the external signal terminal block as needed. Refer to Section 4.4 and Figure
4-16 thru Figure 4-19 for functional description. 14 AWG (2mm
conductor is recommended.
