Safety Summary
Electrostatic Sensitive Device
Devices labeled with this symbol require special handling precau-
tions as described in the installation section.
GENERAL Equipment Environment
WARNINGS All components, whether in transportation, operation or storage,
must be in a noncorrosive environment.
Electrical Shock Hazard During Maintenance
Disconnect power or take precautions to insure that contact with
energized parts is avoided when servicing.
SPECIFIC Verify the main power, field power, and power entry panel circuit
WARNINGS breakers/switches are turned off before starting installation, retrofit,
upgrade, or wiring procedures. Failure to do so could result in
severe or fatal shock. Do not turn the power on until the installation,
retrofit, upgrade, or wiring procedures are complete. (p. 2-6)
Never clean electrical parts or components with live power present.
Doing so exposes you to an electrical shock hazard. (p. 3-3)
Wear eye protection whenever working with cleaning solvents.
When removing solvents from printed circuit boards using com-
pressed air, injury to the eyes could result from splashing solvent as
it is removed from the printed circuit board. (p. 3-3)
There are exposed AC and DC connections inside the cabinet.
These exposed electrical connections present a shock hazard that
can cause injury or death. (p. 3-4)
If input or output circuits are a shock hazard after disconnecting sys-
tem power at the power entry panel, then the door of the cabinet
containing these externally powered circuits must be marked with a
warning stating that multiple power sources exist. (p. 3-4)
