2.
Remove the battery pack assembly from the housing:
A.
Loosen the captured screw from the battery pack cover plate, using
the 7/64-inch Allen wrench included with the shipment.
B.
Lift the battery pack assembly straight out of the housing, using
the handle.
3.
Keep the handle in an upright position. Holding the edge of the
yellow
cover plate, unscrew the cover plate from the battery pack assembly.
Note: Older SBE 37-SM MicroCATs use a battery pack with a red cover
plate; the wiring of that pack is different from this one, and
cannot be
used with this 37-SM
.
4.
Roll the 2 O-rings on the outside of the battery pack out of their grooves.
5.
Insert each cell into the pack,
alternating
positive (+) end first and
negative (-) end first to match the labels on the pack.
6.
Roll the 2 O-rings on the outside of the battery pack into place in the
grooves. The O-rings compress the side of the battery pack and hold the
cells tightly in place in the pack.
7.
Reinstall the battery pack cover plate:
A.
Align the pin on the battery pack cover plate PCB with the post hole
in the battery pack housing.
B.
Place the handle in an upright position. Screw the yellow cover plate
onto the battery pack assembly. Ensure the cover is tightly screwed
on to provide a reliable electrical contact.
8.
Replace the battery pack assembly in the housing:
A.
Align the D-shaped opening in the cover plate with the pins on the
shaft. Lower the assembly slowly into the housing, and once aligned,
push gently to mate the banana plugs on the battery compartment
bulkhead with the lower PCB. A post at the bottom of the battery
compartment mates with a hole in the battery pack’s lower PCB to
prevent improper alignment.
B.
Secure the assembly to the shaft with the captured screw, using the
7/64-inch Allen wrench. Ensure the screw is tight to provide a
reliable electrical contact.
9.
Reinstall the I/O connector end cap:
A.
Remove any water from the O-rings and mating surfaces in the
housing with a lint-free cloth or tissue. Inspect the O-rings and
mating surfaces for dirt, nicks, and cuts. Clean as necessary. Apply a
light coat of O-ring lubricant (Parker Super O Lube) to the O-rings
and mating surfaces.
B.
Plug the female end of the Molex connector onto the pins.
C.
Carefully fit the end cap into the housing until the O-rings are
fully seated.
D.
Reinstall the 2 cap screws to secure the end cap.
