INSTALLATION
IEPEP04 POWER ENTRY PANEL WIRING
I-E96-508C 3 - 5
2. Connect 24 VDC or 48 VDC primary (L1) input power to
TB3 (+), TB4 (-) and TB5 (GND) (Figure
C-1 ).
3. Connect the secondary (L2) DC power input (if used) to
TB5 (GND), TB6 (-) and TB7 (+). Both inputs must be the same
nominal voltage level. If only 1 DC power input is being used,
proceed with Step 4. If not, skip to Step 5.
4. Connect TB3 to TB7 and TB4 to TB6. Use 6 AWG wire.
Note that this step avoids false status information because it
connects line 1 and line 2 inputs together.
5. Connect cable 6637813_1 from J2 on the power entry
panel to the system power bus bar. This provides connections
to sample the DC output bus voltages, monitor the power mod-
ule status signal and to output a power fail interrupt signal.
See the wiring diagrams at the end of this manual (Figure
C-1 )
for correct system power bus bar connections.
6. Connect cable 6639443_1 from TB8, TB9, TB10, TB11 and
TB12 on the panel to the input power bus bar for distribution
of DC power to the module mounting unit (Figure
C-1 ).
7. Connect cable 6637818_2 from the input power bus bar to
each module mounting unit backplane (Figure
C-1 ).
8. Connect the fan assembly power cable to connector J1
labeled FAN OUT on the panel (Figure
C-1 ).
9. Connect a wire equivalent to power wiring but not less
than 6 AWG from the TB10 (GND) stud of the panel to the cab-
inet frame for DC input safety grounding (Figure
C-1 ).
10. There are 2 extra voltage monitor inputs available to moni-
tor customer external power supply voltages (see Figure
C-1 ).
Use terminal block TB2 labeled AUX BUS MONITOR for this
purpose. Attach one input to terminals 1(+) and 2(-) labeled
CH1. Connect the other input to terminals 3(+) and 4(-) labeled
CH2. Inputs can be 24 VDC, 48 VDC or 125 VDC. Set jumpers
J1 and J2 for the desired voltage. Refer to Table
3-2 .
11. Wire the status inputs to terminal block TB1, terminals 1
(STATUS IN 1), 2 (COM) and 3 (STATUS IN 2). Insure that the
inputs are open collector or contact type referenced to DC
common (terminal COM). The alarm inputs must have the cur-
rent carrying capability to sink at least 1 mA. If the system
uses Plant Loop, do Step 12. If not, go to Step 13.
12. Connect cable 6634205_1 from TB1 terminal 4 STATUS
OUT to the P3 card edge connector of the bus interface module
(BIM). Doing so enables the BIM to send the status message to
