The following illustrates the recommended power connections for using a vehicle electrical system as the SomatXR system power source. The included diagrams are not intended to be complete, detailed instructions.
CAUTION
Connection to the positive power terminal without proper grounding may result in a blown fuse and/or other damage to the SomatXR system.
NOTE
When using additional cable length to make the connections, select an appropriate gauge wire to carry sufficient current (≥10 amps) and voltage (≥12 volts).
Refer to the following vehicle powering sections:
The following diagram illustrates the proper method of powering a SomatXR system with a direct connection to a vehicle battery that has a permanent ground connection to the vehicle chassis.
An alternate method, shown below, uses a vehicle electrical system or harness which may be a switching supply such as an ignition or a relay type device. This method, while feasible, is not recommended and cannot be guaranteed as safe. Results may include unwanted multiple runs of data, improper reboots, lost data due to multiple power cycles and improper charging of the internal battery pack.
For a system with a switched power system that removes the negative battery terminal from the equipment chassis ground, carefully follow the illustrated recommendation below.
CAUTION
Failure to follow these suggestions may result in blown fuses and/or permanent damage to SomatXR modules. Improper powering of the unit requiring repairs by HBM technicians may be deemed as non-warranty usage, resulting in service charges.
The figure below shows an example of improper powering that may result in damage to a SomatXR module.
