After the completion of the input power cables connection:
With a phase rotation meter, check that the phase rotation of the AC Input power
terminals A, B and C as well as the Bypass Input power terminals A40, B40 and C40 are
correct. The proper phase rotation is clockwise A(R)
NOTE
3. Connect the grounding conductor from the input service
entrance to the UPS Ground Bar (E).
4. Two (2) sources feeding the UPS:
(1) 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 and Figure 5-2. 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 5). Connect the bypass input power cables from the
input service entrance to the bypass input power terminals, identified as A40, B40 and C40 in
Figure 5-1 and Figure 5-2. 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 desired. Refer to Section 4.4.1 and Figure 4-18
for functional description. 14 AWG (2mm
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 Figure 5-1 and Figure 5-2. 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 and Figure 5-2, connect jumper bypass terminals A40, B40, C40 to AC input power
terminals A, B, C as identified in Figure 5-1 and Figure 5-2.
