Wiring Vehicle Power And Communications To The Cradle; Extreme Wet Environments - Motorola 7545MBW User Manual

4 - 24 Omnii Hand-Held with Windows CE 6.0 User Manual
• Ensure the power connector is wrapped securely with a waterproof electrical tape and installed in a dry
location on the vehicle, away from the vehicle operator's reach (perhaps under a vehicle dash or in a
sealed housing).
• Cover the power connector with a waterproof heat shrink material (see
page 4-24 for additional details).
All other installation requirements outlined in this document should also be followed for High Voltage vehicles
to insure safe installation and operation of the powered cradle.

Extreme Wet Environments

For extreme wet environments, or environments where it is difficult to restrict vehicle operator access to the
power connector, Motorola offers a waterproof heat shrink kit (PN 1030022). The kit contains 3 pieces of water-
proof, high shrink ratio heat shrink tubing which can be used to encapsulate the entire connector assembly. If
using this kit, please ensure that you order sufficient material to cover installation and service, remembering
that heat shrink is one-time use, and must be replaced if it is removed from the connector for any reason.

Wiring Vehicle Power and Communications to the Cradle

An optional 1.8 meter (6 foot) extension power cable (PN 13985-301 with motion detect or 13985-302) is avail-
able for your powered vehicle cradle. This cable should be wired to a filtered, fused (maximum 4A) accessory
supply on the vehicle. The power cradle draws no more than 4A (less if the accessory supply is greater than
12V). Any additional wiring, connectors or disconnects used should be rated for at least 10A. Installation of the
19440-XXX fuse assembly using a 4A 250V fuse installed is mandatory, except when using a CA3002 vehicle
power cable. The 13985-XXX cables are not used with the CA3002. The 4A fuse is already included in the
CA3002 vehicle connector assembly.
NOTE
When connecting PN 13985-301 (Screen Blanking version), ensure that the screen
blanking wires (clearly labelled) and the power wires (red/black leads) are reliably
secured away from each other, or are separated with reliably secured certified insula-
tion. A minimum 2.8mm distance, or 0.4mm distance through insulation, is required
for the separation.
The red lead of the power cable attaches to the positive vehicle supply. The black lead connects to the nega-
tive supply — this should be connected to a proper terminal block and not to the vehicle body.
You may have the option of connecting power before or after the key switch. It is preferable to wire the power
cradle after the key switch — that is, it cannot be turned on without the key on. However, if the operator
switches the key off repeatedly for long periods during a shift, it may make more sense to wire the cradle
before the switch.
Keep in mind that the Omnii will continue to operate with or without vehicle power as long as its battery has
sufficient charge. If an unfused power source must be used, a fuse assembly (PN 19440-300) must be added
to the extension power cable (the fuse and instructions are supplied with the cable). Use only a 4A fast blow
UL approved fuse in the fuse assembly (PN 9016622).
WARNING
11.5–30 Vdc input only, suitable for road vehicles. A pre-regulator is
required for use on forklifts. For such installations Motorola recommends
using the PS1350 (15-90 VDC) pre-regulator or, for freezer applications,
the PS1370 pre-regulator.
