b. Coat the O-ring’s sealing surface with a silicone lubri-
cant. (A small quantity of lubricant is supplied in the
maintenance kit.)
CAUTION
Do not use petroleum-based lubricants. Petroleum-based
lubricants will cause the O-ring to swell and eventually deterio-
rate. Aerosol silicone lubricant sprays often use petroleum
based propellants. If you are using an aerosol spray, allow a
few minutes for the propellant to evaporate before proceeding.
3. Place the carrying handle on the battery module. (If you
are stacking two 2150EX modules on top of the
2191EX/2196EX, position the handle between the 2150EX
modules.)
4. Unlock the 2150EX module’s latch by pressing in on the
latch release (right side).
5. Underneath the 2150EX, remove the cap from the lower
communication connector and stow it in the holder.
6. Lock the latch. Locking the latch correctly seats and aligns
the lower cap in its holder.
7. Position the 2150EX over the 2191EX/2196EX battery
module. Align the connectors and lower the 2150EX onto
the 2191EX/2196EX.
8. Unlock the 2150EX module’s latch by pressing in on the
latch release (right side).
9. Firmly press the modules together and lock the 2150EX
module’s latch (left side).
The communications indicator will blink during the start-up
routine to indicate the 2150EX is operating.
Note
Unused communication ports on the top and bottom of the
stack must be capped. The connector caps terminate the com-
munication lines and protect the pins.
