FIGURE 2-2. INSTALLATION OF MODEL BIT 4882-F INTO BOP (SHEET 1 OF 2)
NOTE: Step numbers coincide with encircled numbers on Figure 2-2, sheet 2.
Step 1. Remove a-c power to BOP by disconnecting line cord.
Step 2. Remove BOP cover (see Section 5, Figure 5-1 of your BOP Instruction Manual).
Step 3. Remove and discard Rear Cover Plate (PN 128-1434) and associated hardware.
Step 4. Remove J204 Connector Assembly (PN 241-0680) from Location #1, save for Step 9.
Step 5. Locate Transformer T202 and unplug connector from Location #4 only.
Step 6. Locate Rear Bracket and note part number (stamped on outside left edge):
if not PN 128-1810, contact Kepco.
Step 7. Unpack the BIT 4882-F Interface Card Installation Components (Transformer, PCB
Assembly, Cables #1 and #2, Connector Assembly, three (3) Knurled Nuts, five (5) wash-
ers, Spacer and Bracket).
Step 8. Install PCB Assembly (PN 235-1166) into the guides, slide into position so that mounting
holes in PCB Assembly line up with the three mounting posts on the BOP mounting
bracket.
Step 9. Secure the BIT 4882-F Interface Card to the Mounting Posts using the Knurled Nuts and
Lockwashers. Mount Connector J204 (Ref. Step 4, above) into Location #3 using the Lock-
washers, Hex Spacer and Knurled Nut.
Step 10. Install Cable #1 (18-position connectors) to the BIT 4882-F Interface Card; mate the other
end of the cable with Location #1 on BOP A1 Assembly.
Step 11. Install Cable #2 (5-position connectors) to the BIT 4882-F Interface Card; mate the other
end of the cable with Location #2 on BOP A1 Assembly.
Step 12. Plug in 3-pin connector (Ref. Step 5, above) from Transformer 100-2354 as shown.
Step 13. Plug in Ribbon Cable Assembly 195-0085 as shown. Secure ribbon cable connector to
chassis using knurled nut.
Step 14. Mark "-4882" after Model No. on Nameplate (see Detail A).
Step 15. Remove "Control Identification" label (PN 188-1107) and "Address Label" (PN 188-1012).
Affix revised "Control Identification" label (PN 188-1445) and "Address Label" (PN
188-1726) in vacated positions (with part numbers facing front panel).
Step 16. Reinstall BOP cover.
Step 17. Perform calibration procedure detailed in Section 3 of this manual.
