INSTALLATION OF INTERFACE CARD INTO THE BOP
Refer to Figure 2-2 to install the BIT 4886 interface card.
CAUTION: The BIT 4886 card contains ESD sensitive components. Follow all proce-
dures in effect at your facility for handling ESD sensitive components.
NOTE: Step numbers coincide with encircled numbers on Figure 2-2.
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 128-1566) and associated hardware.
Step 4. Remove J204 Connector Assembly (PN 241-0680) from Location #1, save for Step 8.
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 PN 128-1810 proceed to Step 7.
if not PN 128-1810, stop installation. Unit does not meet minimum requirements;
contact Kepco for assistance.
Step 7. Unpack the BIT 4886 Interface Card Installation Components (PCB Assembly, Cables
#1 and #2, Connector Assembly, three (3) Knurled Nuts, five (5) washers, Spacer and
Bracket).
Step 8. Install BIT 4886 Interface Card into the guides, slide into position so that mounting
holes in PCB Assembly line up with the two mounting posts on the BOP mounting
bracket.
Step 9. Secure the BIT 4886 Interface Card to the Mounting Posts using the Knurled Nuts and
Lockwashers. Mount Connector J204 (Ref. Step 4, above) into Location #3 using the
Lockwashers, Hex Spacer and knurled nut.
Step 10. Install Cable #1 (18-position connectors) to the BIT 4886 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 4886 Interface Card, mate the other
end of the cable with Location #2 on BOP A1 Assembly.
Step 12. Plug in 3-pin Connector from Transformer 100-2354 (removed in step 5) into BIT 4886
Card, Location #5.
Step 13. Mark “-4886” after Model No. on Nameplate (see Detail A).
Step 14. On BOP cover, peel off “Address Label” (PN 188-1012). Affix revised “Address Label”
(PN 188-1726) in vacated position (with part number facing front panel).
Step 15. Initialize the GPIB per PAR. 4.2, then proceed to step 16.
Step 16. Perform calibration procedure detailed in Section 3 of this manual.
Step 17. Reinstall BOP cover.
