SAFETY SUMMARY
WARNING
WARNING
Do not connect more than two LRUs (the digital processor T/S and the LRU under
test) to power junction box C5A6 at the same time. If more than two LRUs are
connected simultaneously to power junction box C5A6, power supplies C5A9 and
C5A10 can be overloaded. Overloading the power supplies can cause a fire or
explosion that is harmful to personnel and can damage equipment.
WARNING
Trichlorotrifluoroethane, trichloroethane, and similar chemical solvents are no
longer used for ordinary cleaning of equipment. These substances threaten public
health and the environment by destroying ozone in the earth's upper atmosphere.
Suitable nonhazardous cleaning materials are used instead (i.e., use a clean cloth
dampened with water and a mild detergent or with an approved substitute solvent).
WARNING
Extremely high current can be generated by accidentally shorting voltages to
ground. Conductive jewelry, especially rings and watches, that could come in
contact with the hardware should be removed.
WARNING
Before performing any repair procedure, power must be removed from the digital
processor T/S by disconnecting cables from connectors 114 and J15.
B
TM 11-6625-3291-13
WARNING
High voltage and low voltage/high current are used in the operation of this
equipment. Ensure that all power is disconnected from connectors J14 and J15
when any maintenance procedure is performed. When performance
test/troubleshooting procedure is being performed, care must be taken to avoid
contacting high-voltage connections or grounding the high-current sources when
operating this equipment. Injury or death may result if personnel fail to observe
safety precautions.
Caution
This equipment contains parts and assemblies sensitive to damage by
electrostatic discharge (ESD). Use ESD precautionary procedures when touching,
removing, or inserting printed circuit card assemblies.
ESD
CLASS 1
GENERAL HANDLING PROCEDURES FOR ESDS ITEMS
• Use wrist ground straps or manual grounding procedures.
• Keep ESDS items in protective covering when not in use.
• Ground all electrical tools and test equipment
• Periodically check continuity and resistance of grounding system.
• Use only metallized solder suckers.
• Handle ESDS items only in protected areas.
MANUAL GROUNDING PROCEDURES
• Make certain equipment is powered down.
• Touch ground prior to removing ESDS items.
• Touch package of replacement ESDS item to ground before opening.
• Touch ground prior to inserting replacement ESDS items.
ESD PROTECTIVE PACKAGING AND LABELING
• Intimate covering of antistatic material with an outer wrap of either type 1 aluminized material or conductive plastic
film or hybrid laminated bags having an interior of antistatic material with an outer metallized layer.
• Label with sensitive electronic symbol and caution note.
C
TM 11-6625-3291-13
Caution
Be sure to set power switch at power supply C5A9 OFF while removing and
installing CCAs in the digital processor T/S.
Caution
When performing steps in the digital processor T/S performance test and
troubleshooting procedure, when prompted by the computer via the VDT to replace
or reseat a CCA within the digital processor T/S, remove power cable from
connector J15 prior to performing that step.
