5. Drill two 3/16-inch holes in the back of the Mini-Max enclosure as specified by the information included
in the kit. Remove any metal shavings from the enclosure.
6. Clean the 100G Datalogging FN remote ERT modules with the alcohol wipe where you will place the
Corrected and Uncorrected labels (included in the kit).
Note Clean the Datalogging FN remote ERT modules with the alcohol wipe to ensure good label
adhesion.
7. Mount the module for corrected pulse outputs on the left bracket mounting space. Insert three #8-32 x 1/2-
inch screws in a triangular pattern. Install the top screw so the head of the screw is approximately 1/8-inch
from the Endpoint Mounting Bracket surface. Slide the module onto the screw so the mounting lug fits
securely onto the screw. If necessary, remove the module and make any necessary adjustment to the screw
depth to ensure a secure fit. Install the two bottom screws in an alternating fashion.
8. Mount the module for uncorrected pulse outputs on the right bracket mounting space. Insert three #8-32 x
1/2-inch screws in a triangular pattern. Install the top screw so the head of the screw is approximately 1/8-
inch from the Endpoint Mounting Bracket surface. Slide the endpoint onto the screw so the mounting lug
fits securely onto the screw. If necessary, remove the module and make any necessary adjustment to the
screw depth to ensure a secure fit. Install the two bottom screws in an alternating fashion.
9. Route the module cables under the bracket edge and toward the rear of the Mercury Instrument.
10. Mount the Endpoint Mounting Bracket (Mercury Instrument part number 22-1077, included in the kit)
onto the Mini-Max enclosure. Place a #8 metal flat washer followed by a rubber sealing washer onto both
#8-32 x 3/8" screws. Align the lower threaded holes in the mounting bracket with the drilled enclosure
holes and insert a screw/washer through the enclosure housing. Screws heads must be inside the enclosure.
Tighten both screws using a screwdriver.
Note Aligning the second bracket threaded hole and drilled hole may require some manipulation of the
mounting bracket.
11. Insert the module cables (both units) through the large cable strain relief on the left rear of the instrument's
enclosure. Leave a one-half to one inch drip loop under the cable strain relief.
12. Secure three cable ties on the module cables in three places on the cables as specified by information
included in the kit.
13. Re-install the input switchboard, main board, and battery pack removed in step 2.
14. Connect the corrected module wires to TB1 on the Mini-Max board following the table below. Use
Mercury upgrade kit 40-2678-1 to provide the second pulse output channel for the uncorrected ERT
module.
