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 3.1. 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 1-4). 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 3.1 to
3.2. 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 recommended cable sizes.
(2) Connect the external signal terminal block as desired. Refer to section 2.4 and Figure 2.10 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 Figures 3.1 to 3.2. 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 3.1
to 3.2, connect jumper bypass terminals A40, B40, C40 to AC input power terminals A, B, C as
identified in Figures 3.1 to 3.2.
(3) Connect the external signal terminal block as desired. Refer to section 2.4 and Figure 2.10 for
functional description. 14 AWG (2mm
CAUTION : UPS power terminals are supplied with stud type fittings.
6. Procedure for Cable Connections for Parallel Operation System
(1) Confirm the number of units to be connected in parallel. Identify the input/output power terminal
blocks and control wire connections for parallel operation systems as shown in the appropriate
Figures 3.4 and 3.5.
(2) Connect the external control wire and power wire.
a.) Control wire connections
