VML750 Installation
Installing the VML750 LTE Vehicular Subscriber Modem (VSM) involves unpacking and inspection,
planning, cable routing, installation of the antenna, brackets, VSM, SIM card, CryptR card, and cap,
and powering the VSM.
VML750 Unpacking and Inspection
Unpack your equipment and check the contents to ensure that you have received all the specified
items.
Thoroughly inspect the equipment for shipping damage as soon as possible after delivery. Report any
damage you find to your Motorola Customer Service representative immediately.
Safety and General Information
IMPORTANT: This device requires professional installation to satisfy compliance with FCC
requirements.
A properly installed VML750 minimizes service calls. When mounting the VML750 components,
consider the following factors:
• The mounting surface must have sufficient strength to support the equipment being mounted and to
prevent it from becoming loose over time.
• Do not attach components to any part of the vehicle subjected to excessive vibration.
• Do not mount the VML750 unit on a flat surface where the unit could become partially submersed in
water.
• The proposed location of the equipment being mounted or wires/cables attached must not interfere
with driver/passenger seating or leg space.
• Select a location such that heat from the unit does not damage any wiring or any other plastic or
heat-sensitive parts of the automobile.
• Use the supplied mounting hardware.
• Leave sufficient space around the VML750 unit for air flow and installation.
• Select a location that permits routing the cables as directly as possible.
• Ensure that the cables are not stretched, and not subject to heat from the engine, transmission
housing, or heating ducts.
• Crimp connectors securely.
• Do not run cables over sharp edges that may cause excessive wear or chaffing of the cable
insulation.
• Do not install components in locations where they may cause interference to the operation of the
vehicle controls.
• Only qualified personnel may install communication equipment.
• Ensure secure tightening of cable connectors.

WARNING: VEHICLES EQUIPPED WITH AIR BAGS
An air bag inflates with great force. DO NOT place objects, including communications equipment, in the
area over the air bag or in the air bag deployment area. Improperly installed communication equipment
which causes the air bag to inflate could cause serious injury. If necessary, contact the vehicle
manufacturer for air bag information specific to the vehicle.
WARNING: Verify that no vehicle systems are affected by use of the unit, for example, cruise control,
ABS breaking, traction control, engine management, direction indicators, and lights.
WARNING: Use existing openings through the firewall to avoid drilling. If drilling is a must, verify not
to damage the Vehicle ECMs, fuel lines, brake lines, and/or cable looms.
WARNING: For vehicles equipped with electronic braking systems, see Anti-Skid Braking
Precautions, Motorola publication 68P81109E34.
Modems installed in vehicles fueled by liquefied petroleum gas must conform to the National Fire
Protection Association standard NFPA 58, which applies to vehicles with liquid propane (LP) gas
container in the trunk or other sealed off space within the interior of the vehicle.
The NFPA 58 requires the following:
1 The space in which the LP gas container and its fittings are located must be isolated by a seal from
the space containing modem equipment.
2 Removable (outside) filling connections must be used.
3 The container space must be vented to the outside.
CAUTION: Installing the VML750 at the end of the vehicle above the exhaust pipe may cause the
VML750 to overheat.
CAUTION: Check the required mounting locations. It might be necessary to penetrate the firewall to
reach the battery. Before drilling commences, ensure cable clearance on the opposite side of the firewall
and do not install the vehicle Electronic Control Modules (ECMs) on the opposite side of the firewall.
Protect the cable where it passes through the firewall by using a grommet or similar protective
measures.
IMPORTANT: Install this product in a vehicle in accordance with the vehicle manufacturer guidelines and
the instructions detailed in this manual. Use only the Motorola parts specified in this manual.
IMPORTANT: Refer to the Safety Instructions in Product Safety and RF Energy Exposure Booklet for
Mobile Two-Way Radios Installed in Vehicles or as Fixed Site Control Stations P/N 6881095C99 (for
USA) or RF Energy Exposure and Product Safety Guide for Mobile Two-Way Radios installed in Vehicles
or as Fixed Site Control Stations P/N 6866537D37 (for EU).

VML750 Installation Planning
Fast, easy, and safe installation requires careful planning and selecting the proper location. For optimal system
performance, follow the instructions and recommendations detailed in this manual.
Perform this process to install the VML750 LTE Vehicular Subscriber Modem (VSM).
Process:
1 Ensure adequate space for the installation.
2 Install the Antennas. See Mounting the VML750 Antennas. Also see the Installation Guide supplied with
each antenna.
3 Route the cables. See VML750 Cable Routing and Connection.
4 Install the brackets and the unit. See Installing the VML750 Modem.
5 Connect the DC Power and Ignition cable. See Installing the DC Power and Ignition Cable.
6 Connect the main antenna cables. See Installing Antenna Cables.
7 Connect the LAN/Ethernet cable. See Installing the LAN/Ethernet Cable, or the Micro USB cable,
See Installing the Micro USB Cable.
8 Power-up the VML750. See Powering Up the Modem.
The VML750 can be installed on a flat surface or a side wall of a vehicle.
Before beginning the installation, make sure that the space available at the installation site is adequate for the
modem and its accessories. Each installation configuration may require a different area for mounting the modem
without obstruction.
When choosing a location, ensure easy access for installation and replacement of the unit.
Vehicle RF Antennas must be installed in external to the vehicle and in accordance with:
• The requirements of the antenna manufacturer/supplier.
• Instructions provided in installation manuals of other radio devices installed next or used with the
VML 750.

Chapter 2: VML750 Installation
Cable Routing
• Before running a wire or drilling a hole, inspect the vehicle to determine how and where you intend to
mount the antenna, modem, and input/output device.
• Before installing the antenna cables, add an identical label on both ends of each cable to ensure correct
connection between the antenna and its related connector on the VML750 back panel.
• Plan wire and cable routing to provide maximum protection from overheating, battery acid, moving parts,
and sharp edges.
• Keep cables away from ignition circuits to reduce noise pickup in the radio equipment.
• Verify that the cables are of sufficient length. Do not connect two short lengths with a splice; doing so
results in power loss. Refrain from loose excess in the cables, but leave enough slack to allow re-
connection if necessary.
• Do not run cables externally or underneath floor mats.
• Do not locate cables where the driver or passengers can kick them or where they can interfere with
operation of the driver foot pedals.
• When routing the cables, do not create sharp bends or kinks.
NOTICE: For detailed antenna cables routing instructions, see the Installation Guide supplied with
each antenna.
Cable Holes
• Where possible, use existing holes in the firewall, the trunk wall, and the channels above or beneath
the doors.
• If you must drill holes, do not damage other wiring, brake lines, or fuel lines.
• When drilling a hole in the roof, do not snag the roof liner.
• To prevent rusting after drilling, remove all metal burrs and residue, and completely clean the area to
ensure the removal of all steel dust.
• Insert rubber grommets in all drilled holes to protect cables, except for Antennas cables.
