How To Install FMA120 Units
[Image: fma120.png]
Follow the instructions below to install the FMA120 Units
Connecting Wires
  1. Wires should be connected while module is not plugged in.
  2. Wires should be fastened to the other wires or non-moving parts. Try to avoid heat emitting and moving objects near the wires.
  3. You should not be able to see the wiring and connections clearly. If factory isolation was removed while connecting wires, it should be applied again.
  4. If the wires are placed in the exterior or in places where they can be damaged or exposed to heat, humidity, dirt, etc., additional isolation should be applied.
  5. Wires cannot be connected to the board computers or control units.

Connecting a Power Source
  1. Make sure that power is still available on the chosen wire after the car computer falls asleep. Depending on the car, this may happen in 5 to 30 minute period.
  2. When the module is connected, measure voltage again if the voltage doesn't increase.
  3. We recommend that you connect to the main power cable in the fuse box.

Connecting Ignition Wire
  1. Make sure you check if it is a real ignition wire – power should not not disappear while starting the engine
  2. Check that this is not an ACC wire (when key is in the first position, most electronics of the vehicle are available).
  3. Check if power is still available when you turn off any of the devices in the vehicle.
  4. Ignition is connected to the ignition relay output. Any other relay, which has power input when ignition is on, may be chosen as an alternative.

Connecting Ground Wire
  1. Ground wire is connected to the vehicle frame or metal parts that are fixed to the frame.
  2. If the wire is fixed with the bolt, the loop must be connected to the end of the wire.
  3. For better contact, scrub paint from the place where the loop is connected.

Module Installation
  1. The FMA120 must be placed with the sticker on TOP (please refer to the picture below).
  2. It is forbidden to place the FMA120 under metal surfaces.
  3. It’s recommended to place the FMA120 device far from the car radio, speakers or alarm systems.
  4. The FMA120 must be placed so its state is as horizontal as possible.
  5. The FMA120 should not be seen or easily reached.
  6. The FMA120 should be firmly fixed to the surface or cables.
  7. The FMA120 cannot be fixed to heat emitting or moving parts.
  8. The SIM card should be inserted in the module while the connector is plugged off (while the module has no power).
  9. We recommend that you place the FMA120 device behind your dashboard as close to the window as possible. A good example of device placement is displayed in the graphic  below.

Connecting the power supply must be carried out in a very low impedance point on-board vehicle network.
These points in the car are the battery terminals. Therefore, we recommend connecting the power of FMA120 (wires NEGATIVE and POSITIVE) directly to the battery terminals.
Another valid option is to connect the wires to the main POSITIVE cable inside the fuse box wire (if there is none, then connect to the power supply where the fuses of the vehicle’s computer are). GROUND should be connected to the chassis, or other ground wires.
Connecting the GROUND at an arbitrary point to the mass of the car is unacceptable, as static and dynamic potentials on the line means that GROUND will be unpredictable, which can lead to an unstable FMA120 and potential failure.
