Use the following procedures to wire the SIAC-B to the UPS cabinet.
4.4.1
Installing SIAC-B Internal Power Wiring
To Install wiring:
1.
Locate and remove the three internal power wiring phase harnesses, two neutral harnesses, and MBP
interface harness packed inside the SIAC-B. Retain for later use.
2.
Route the phase harness ends marked for the UPS Output, UPS Bypass, and UPS Input (if installed) from
the SIAC-B through the bottom of the SIAC-B and UPS inter-cabinet wiring access pass-through to the
UPS cabinet terminals. See Figure 4-3 or Figure 4-4 for SIAC-B terminal locations. Refer to the applicable
Eaton 93PM UPS Installation and Operation manual, listed in paragraph 1.7, for the UPS pass-through and
terminal locations.
3.
In the UPS cabinet, locate the harness cable ends marked UPS Output. Connect marked phase
A, B, and C cable ends to the corresponding output terminals of the UPS.
For termination requirements and a detailed view of the UPS output terminal blocks, refer to the
applicable Eaton 93PM UPS Installation and Operation manual, listed in paragraph 1.7.
4.
In the UPS cabinet, locate the harness cable ends marked UPS Bypass. Connect marked phase
A, B, and C cable ends to the corresponding bypass input terminals of the UPS.
For termination requirements and a detailed view of the UPS bypass input terminal blocks, refer to the
applicable Eaton 93PM UPS Installation and Operation manual, listed in paragraph 1.7.
5.
In the UPS cabinet if an RIB is installed, locate the harness cable ends marked UPS Input. Connect
marked phase A, B, and C cable ends to the corresponding rectifier input terminals of the UPS.
For termination requirements and a detailed view of the UPS rectifier input terminal blocks, refer to the
applicable Eaton 93PM UPS Installation and Operation manual, listed in paragraph 1.7.
6.
In the SIAC-B, locate the harness cable ends marked MIS. Connect marked phase A, B, and C terminal
number cable ends to the corresponding terminal number of the MIS breaker.
For a detailed view of the MIS breaker terminals, see Figure 4-5. Tighten terminals to 31Nm (275 lb in)
torque.
7.
In the SIAC-B, locate the harness cable ends marked MIS. Connect marked phase A, B, and C terminal
number cable ends to the corresponding terminal number of the MIS breaker.
For a detailed view of the BIB breaker terminals, see Figure 4-6. Tighten terminals to 31Nm (275 lb in)
torque.
NOTE 1
In the following steps, only two phase harnesses are shipped if an RIB is not
installed.
NOTE 2
Neutral harnesses are only provided with four-wire models.
NOTE 1
When routing cable harnesses, ensure the cables ends marked UPS are routed to
the UPS terminals.
NOTE 2
150 kW SIAC-B phase harnesses have ferrules attached to the each end of the
cables. 200 kW phase harnesses have ferrules attached to the SIAC-B cable ends
and two-hole barrel lugs attached to the UPS cable ends.
