6.3.2 Inspection of Cable Assemblies and Connectors
Inspect all cables attached to the VMBR-1520 as described below.
1. Inspect the cable for dents, twists, flattening, abraded jacket, or
other signs of damage. Observe the bend angle for a wrinkled cable
cover. This is an indicator of an excessively bent cable which may
cause internal cable damage.
2. Inspect the connectors and mating connectors for bent, missing,
recessed, or protruding pins, worn or chipped plating, damaged or
displaced dielectric inserts, thread damage, folded or mushroomed
outer interface rims, mushroomed pin shoulders or pin tips, score
lines on pins and outer surface rims.
3. If any damage is found, repair or replace the cable assembly.
6.4 Cleaning
6.4.1 Cleaning the Chassis
Clean the external surfaces of the chassis periodically using a small
vacuum cleaner or soft brush. Use a small vacuum cleaner to remove
any dust and dirt from the front panel perforated area. In dusty/dirty
conditions, it may be necessary to increase the periodic cycle.
6.4.2 Cleaning Connectors
1. Connectors may contain debris, such as plating chips or other
metal particles, dust or dirt, or oily films, which may degrade or
destroy their connectivity.
2. When cleaning a connector, use isopropyl alcohol. Do not use
chlorinated solvents.
3. Moisten a lint free swab with alcohol to wipe away debris. Do not
over wet the swab. Blow cleaned connectors dry with compressed
air; do not use your breath.
4. Clean the mating connectors using the same procedure.
Caution Failure to
remove any dust and dirt
from the front panel
perforated area periodically
may cause permanent
damage to the unit due to
overheating.
