1. Verify all installed components and peripheral equipment have secure
connections and that there are no bare wires that could cause a short
inside the enclosure.
2. Tighten bulkhead fittings after connecting all 5200A wiring. (Hand tighten
fittings around rubber grommet. Tighten bulkhead fittings into 5200A
enclosure with wrench being careful to not overtighten.)
3. Follow information in Sealants, Desiccants and Securing the Monitor
Section - page 63 to safeguard against damage to internal electronic
components.
4. Make certain the gasket in the front panel lid is in place and not twisted
or damaged.
5. Replace front panel making sure that ribbon cable is not trapped in the
gasket channel before inserting mounting screws.
6. Tighten mounting screws, making sure not to cross thread. The screws are
stainless steel, and the receiving threads are brass. Do not over-tighten!
WARNING: The 5200A utilizes sensitive solid-state devices that can be dam-
aged by static shock. Installers must observe accepted ESD (Electro-Static
Discharge) procedures while connecting cabling to the 5200 I/O plate or to
any other internal component or damage may result.
Control Board
The control board is mounted underneath the I/O board. The serial to ethernet
device and lithium battery are installed on the control board. Complete installation
instructions, including accessing the control board, are provided with the optional
serial to ethernet device. Figure 3.15 shows the control board and I/O board removed
from the 5200A enclosure.

to the equipment.
AVERTISSEMENT : mettez le modèle 5200A à la terre afin d’éviter tout risque
de choc électrique ou d’endommagement de l’équipement.
Ground the 5200A at location E, F or G on the metal plate which is attached to
the lower board assembly - figure 3.16 (shows 5X00 ground to location E) . Other
5200A system components can be grounded at E, F and/or G locations. Titanium
ground rods can also be used to ground peripheral equipment.
In addition to grounding the 5200A, all tanks should be electrically grounded via
a ground probe.
