8 - 10 Replacing Components and Circuit Modules
Issue 8 January 1999
•
Handle all circuit packs by the faceplate or latch and by the
top and bottom outermost edges. Never touch the
components, conductors, or connector pins.
•
Do not rub or wipe circuit packs to clean them unless you
and the circuit pack are at the same ground potential.
•
Observe warning labels on bags and cartons. Whenever
possible, do not remove circuit packs from antistatic bags or
cartons until ready to insert into the rectifier. Otherwise,
open all circuit packs at a static-safe work position with
wrist straps and dissipative table mats.
•
Upon removal from the rectifier, immediately put circuit
packs into antistatic packages. Always store and transport
circuit packs in antistatic packaging. Shielding is not
required unless specified.
•
Keep all static-generating materials away from all circuit
packs. These materials include common plastics such as
food wrappers, clear plastic bags, styrofoam containers,
packing material, drinking cups, notebooks, and
nonconductive plastic solder suckers. The insulation on
small hand tools does not represent a static hazard.
•
Keep adhesive tape (Scotch, masking, etc.) away from
static-sensitive devices.
•
When soldering static-sensitive semiconductor devices, the
soldering iron must be grounded to the work table which
must also be earth grounded.
•
Do not wax the equipment aisles in central offices.
•
Whenever possible, maintain relative humidity above the
20-percent level.
Replacing
Circuit Modules
This procedure gives instructions for replacing the circuit
modules.
Warning
Minimize electrostatic discharge when handling circuit
modules. Do not connect or disconnect circuit modules with
voltages present or equipment damage may occur. AC voltages
may be present when the rectifier Power switch is Off.
CM1 Fuse Board
1. Turn the rectifier Power switch Off.
2. Turn the rectifier CB1 circuit breaker Off (down).
