4.3.1 Tag And Disconnect Electrical Connections
ALL ELECTRICAL SYSTEMS HAVE THE POTENTIAL TO CAUSE SPARKS DURING SERVICE.
TAKE CARE TO ELIMINATE EXPLOSIVE OR HAZARDOUS ENVIRONMENTS DURING SER-
VICE AND/OR REPAIR.
KEEP ALL I/O PORT COVERS IN PLACE DURING USE TO PREVENT WATER DAMAGE.
OTHER ELECTRICAL COMPONENTS MUST NOT BE SUPPLIED FROM THE SAM SYSTEM
SUPPLY. DO NOT CONNECT THE PRIMER AND HALE SAM TO THE SAME POWER WIRE.
THE CONTROLLER UNIT DEUTSCH CONNECTORS ARE KEYED TO PREVENT INTER-
CHANGE OR REVERSE DIRECTION INSERTION. DO NOT FORCE A CONNECTOR WITH-
OUT FIRST VERIFYING THE CONNECTORS ORIENTATION AND PLACEMENT.
THE MODULE DEUTSCH CONNECTORS ARE KEYED; HOWEVER, ALL MODULES UTILIZE
THE SAME TWO KEYS. VERIFY THE HARNESS LABEL AND THE MODULE PART NUMBER
TO ENSURE THE CORRECT MODULE AND HARNESS CONNECTOR ARE BEING CON-
NECTED.
Never attempt to tag, disconnect, or connect an energized circuit.
As a general maintenance practice, tag (document/photograph/record) the connector orientation
and location (including the mating connector) for each component before disconnecting or re-
moving it.
From/To wire listings (pinout) listings are provided for modules, sensors, solenoids, etc., when a
listing is not present herein, refer to the plate drawings located in the SAM PM (FSG-MNL-00212)
