has power output when ignition is on, may be chosen.
Connecting ground wire
Ground wire is connected to the vehicle frame or metal parts that are fixed to the frame.
If the wire is fixed with the bolt, the loop must be connected to the end of the wire.
For better contact scrub paint from the spot where loop is going to be connected.
PAY ATTENTION! Connecting the power supply must be carried out in a very low
impedance point of on-board vehicle network. These points in the car are the battery
terminals. Therefore, we recommend connecting the power of FMC640 (GND and
POWER wires) directly to the battery terminals. Another valid option is to connect the
wires to the main POWER cable inside the fuse box (if there is none, then to the power
supply where the fuses of vehicle's computer are), GND wire must be connected in a
special point, designed to connect GND vehicle computer. Connecting the GND at an
arbitrary point to the mass of the car is unacceptable, as static and dynamic potentials
on the line GND will be unpredictable, which can lead to unstable FMC640 operation
and even its failure.
Safety information
This message contains information on how to operate FMC640 safely. By following these
requirements and recommendations, you will avoid dangerous situations. You must read these
instructions carefully and follow them strictly before operating the device!
The device uses SELV limited power source. The nominal voltage is +12 V DC. The allowed
voltage range is +10..+30V DC.
To avoid mechanical damage, it is advised to transport the device in an impact-proof package.
Before usage, the device should be placed so that its LED indicators are visible. They show the
status of device operation.
When connecting the the 2x10 connector cables, the appropriate jumpers of the vehicle power
supply should be disconnected.
Before unmounting the device from the vehicle, the 2x10 connector must be disconnected.
The device is designed to be mounted in a zone of limited access, which is inaccessible to the
operator. All related devices must meet the requirements of EN 60950-1 standard.
The device FMC640 is not designed as a navigational device for boats.
Precautions
Do not disassemble the device. If the device is damaged, the power supply cables are
not isolated or the isolation is damaged, DO NOT touch the device before unplugging
the power supply.
All wireless data transferring devices produce interference that may affect other
devices which are placed nearby.
The device must be connected only by qualified personnel.
