h. Installation of the W116-1 IPADS DC power cable:
WARNING
To prevent injury to personnel or damage to equipment, remove all rings,
watches, bracelets, etc.
Disconnect negative battery cable before working with or around batteries.
The negative cable is the cable that attaches to the current shunt in the
battery box, figure 2-13.
Protect the negative battery cable from accidental contact with other battery
cables or posts.
When finished with work, connect negative battery cable last.
CAUTION
If the wiring inside the HMMWV's battery box does not reflect figure 2-13 or if
additional communication equipment is connected to the battery box, consult
your maintenance to verify the location of +24VDC. IPADS requires
+24VDC for operation.
NOTE
IPADS can be attached to vehicle power by direct connection to the
batteries or by using the IPADS NATO plug attachment, figure 2-17. The
W116-1 cable, which connects to the vehicle battery terminals, is
recommended for permanent installations. A NATO plug attachment,
which connects to the vehicle's NATO slave receptacle located under the
passenger's seat, may be used with W116-1 cable for temporary
installations.
The NATO plug attachment is for temporary use only.
Use caution when using the NATO plug attachment. It is very easy to
dislodge the plug assembly, causing IPADS to lose vehicle power.
If using the NATO plug, the front commander's seat does not need to be
removed.
(1) Remove front commander's seat by opening latch and lifting seat out of vehicle.
NOTE
The HMMWV battery terminals may be covered with a plastic boot,
out using a flat blade screwdriver.
If the battery terminals were covered with a plastic boot, use the
pocketknife to cut a hole into the side of the plastic boot, figure 2-14. Route
branch of IPADS DC power cable through the hole cut in the plastic boot
before attaching to the battery connectors.
