Electrical Installation
Read warnings chapter on page 5 on this document.
•
Protect power supply lines (6,8...32Vdc) with 3A (max 10A) fuse at power supply end of line.
•
Connect the cables to A1 device and peripherals as advised in the connection guide. Figure 11. IGN- line
•
must be always connected.
Install the GSM/GPRS antenna and cables as far away as possible (minimum 1 metres recommended)
•
from the radio antenna or other electrical devices to avoid any interference.
Additional information: Application note K505002 Cabling of Aplicom Products.
Avoid ground loops! It is highly recommended to connect all A1 and peripherals ground connections to a
•
single point. It is also recommended to use non-grounding antennas.
Insert the SIM card to the SIM card slot. Figure 12.
•
Insert optional Internal battery. Figure 12.
•
Attach the elastic protective cover. Figure 1.
•
A1 device versions with CAN bus functionality ** do not include internal bus terminator resistor (120 ).
•
The led beside the battery connector indicates the battery charging state. When lit:
•
-
Green, battery is fully charged
-
Yellow, charging is in progress
-
Red, indicates an error condition e.g. battery overheating
Disconnecting ground lines shall not be done while unit is connected to power supply of the vehicle. This
•
will cause voltage leak between IO connections causing possible problems in external devices connected
to them.
When digital tachograph is connected to A1 they must share a common ground potential. If the ground
•
potential is not common, the serial connection between units may not work. Use the ground wire of the
provided cable to secure the ground potential.
