Notes
:
1. Use only non-ferromagnetic materials
2. Use this configuration only if 78L05 voltage regular IC5 is installed on controller PCB
3. Each 4-pin sensor connector is supplied with 4 contacts. Only 3 of the contacts are used. Crimp and
solder wire to contact and then insert contact into connector housing. Orient the small tab on the contact so
it slides into the slot on one side of the housing
4. Refer to SAM-III Construction Manual for bonding/grounding information.

5. Other types of cable may be suitable or required. See SAM-III Construction Manual
6. Observe polarity of tantalum capacitors
