•
Remove all conductive personal items (rings, watches, medals, etc.)
•
The work area should be secure and free of non-essential items.
•
Wear safety glasses and protective clothing.
•
Operators should never work alone on high risk devices. There should always be
another person present in the same area to assist in the event of an emergency.
•
Operators should be familiar with procedures to employ in the event of an
emergency, i.e., remove all power, CPR, etc.
Large DC currents are generated to operate the RF Module inside of the enclosure.
EXTREME CAUTION IS REQUIRED WHEN THE ENCLOSURE IS OPEN AND THE
AMPLIFIER IS OPERATING. DO NOT TOUCH ANY OF THE CONNECTIONS ON
THE RF MODULES WHEN THE AMPLIFIER IS OPERATING. CURRENTS IN
EXCESS OF 60 AMPERES MAY EXIST ON ANY ONE CONNECTOR.
1.7.3 RF Transmission Hazards
RF transmissions at high power levels may cause eyesight damage and skin burns.
Prolonged exposure to high levels of RF energy has been linked to a variety of health
issues. Please use the following precautions with high levels of RF power.
•
Always terminate the RF input and output connector
prior to applying prime AC input power.
•
Never look directly into the RF output waveguide
•
Maintain a suitable distance from the source of the
transmission such that the power density is below
recommended guidelines in ANSI/IEEE C95.1. The
power density specified in ANSI/IEEE C95.1-1992 is
10 mW/cm2. These requirements adhere to OSHA
Standard 1910.97.
•
When a safe distance is not practical, RF shielding should be used to achieve the
recommended power density levels.
1.7.4 Electrical Discharge Hazards
An electric spark can not only create ESD reliability problems, it can also cause serious
safety hazards. The following precautions should be followed when there is a risk of
electrical discharge:
•
Follow all ESD guidelines
•
Remove all flammable material and solvents from the
area.
•
All probes and tools that contact the equipment should
be properly insulated to prevent electrical discharge.
•
The work area should be secure and free from non-
essential items.
