testing be done in conjunction with hardware installation. This will ensure that
the 5200A system is wired correctly. Necessary configuration information (from
Chapter 4 -
“Configuration”
) is referenced in the applicable test system procedures.
WARNING: Follow all safety information and local electrical codes when wiring
5200A system components and peripheral devices
.
Proper wire gauge should
be determined based on voltages and wire/cable length. Incorrect wiring can
result in damage to you or to the equipment. Improper wiring can also result
in ground loops.
AVERTISSEMENT : suivez toutes les consignes de sécurité et les codes électriques
en vigueur lors du câblage des composants du système 5200A et des appareils
périphériques. Le calibre correct des câbles doit être déterminé en fonction des
tensions et de la longueur des câbles/fils. Un câblage incorrect peut entraîner
des blessures et endommager l’équipement. Un câblage incorrect peut également
entraîner des boucles de mise à la terre.
5200A Bulkhead Fittings
Three bulkhead fittings [2@ 3/4” (1.905cm) and 1@ 3/8” (.9525cm)] located at the
bottom of the 5200A enclosure provide watertight entry points for 5200A system
wiring. The probe/cable assembly connector is located below the bulkhead fittings
- figure 3.13. Rubber grommets must be “pushed out” of the compression fitting
housing and drilled for wiring installation. The drill bit diameter should be slightly
smaller than the wire diameter so that a watertight seal can be made. Rubber
grommets can be frozen (put in a freezer for 1 hour) and then easily drilled to the
required diameter. Some pre-drilled rubber grommets are supplied with the 5200A.

Accessing the I/O Board
The I/O board is accessible when the 5200A front panel is removed. The letters
on the metal plate, which is attached to the lower board assembly, identify ground
wire termination locations and pluggable terminal strip locations on the I/O board.
Letters on the metal plate correspond to the wiring diagram located on the inside of
the front panel - figure 3.14. A ribbon cable connects the display board (mounted
in the front panel) to the I/O board. When the 5200A front panel is removed, a
lanyard protects against stress on the ribbon cable. See
Open Front Panel to Access
I/O Board - page 40.
