Section 3: Preparing MicroCAT for Deployment 

SBE 37-SM RS-232

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. 

Handle 

Loosen 
captured 
screw 

Roll 2  
O-rings 
out of 
grooves 

Roll  
2 O-rings 
into 
grooves 
after 
inserting 
cells 

Align pin in cover 

plate with post hole 

in battery pack 

Pins on 
shaft 

CAUTION: 
Do not use Parker O-Lube, which  
is petroleum based; use only  
Super
 O-Lube.
