GROUNDING
All cable shields must be grounded to avoid interference from AC wiring, fluorescent lights, or
other high magnetic or RF fields.
NMEA data cables should be grounded at the source. All other cables should be grounded at both
ends. The equipment in the VDR enclosure is grounded to the rack. All other peripheral equipment
should be grounded.
CABLING
The cable sizes and types recommended for use with the must be utilized to ensure its proper
operation. Failing to do so will void the warranty.
HEALTH HAZARD
This equipment contains materials which produce toxic fumes when ignited.
The inhalation of dust and fumes or any contact with lubricants when cleaning the equipment may
be temporarily harmful to health, depending on individual allergic reactions. Components which
are broken or overheated may release toxic fumes or dust and must be treated with caution. Do
not inhale the fumes and ensure that the dust and debris do not enter open cuts or abrasions. It
is prudent to regard all damaged components as being potentially toxic, requiring careful handling
and appropriate disposal.
ELECTROSTATIC DISCHARGE
Digital devices are susceptible to damage from electrostatic discharge (ESD); certain
precautions must be taken when handling circuit cards, integrated circuits (ICs), and other
sensitive devices.
The maintenance technician should conform to the following guidelines when handling ESD
sensitive devices:
1. Always wear a static protection wristband prior to contact with any electrostatic sensitive
device.
2. Ensure that the wristband cable clip is firmly attached to a grounding point.
3. Keep all sensitive components in their protective pouches until required.
