INSTRUCTIONS FOR SAFE OPERATION
Revised 0517
HAZARDOUS RF VOLTAGES
The RF voltages on the center pin of an RF output connector can be
hazardous. The RF output connector should be connected
to a load before AC power is applied to the equipment. Do
not come into contact with the center pin of the RF output
connector or accessories connected to it. Place the
equipment in a non-operating condition before disconnecting or
connecting the load to the RF output connector.
ACOUSTIC LIMITATIONS
If equipment noise exceeds 80dB, ear protection is required.
MAINTENANCE CAUTION
Adjustment, maintenance, or repair of the equipment must be
performed only by qualified personnel. Hazardous energy may be
present while protective covers are removed from the equipment even
if disconnected from the power source. Contact may result in personal
injury. Replacement fuses are required to be of specific type and
current rating.
ENVIRONMENTAL CONDITIONS
Unless otherwise stated on the product specification sheet, this
equipment is designed to be safe under the following environmental
conditions:
• Indoor use
•
Altitude up to 2000m
• Temperature of 5°C to 40°C
• Maximum relative humidity 80% for temperatures up to 31°C.
Decreasing linearly to 50% at 40°C.
•
Main supply voltage fluctuations not to exceed ± 10% of the
nominal voltage or minimum and maximum autoranging values.
• Pollution degree 2: Normally non-conductive with occasional
condensation. While the equipment will not cause hazardous
condition over this environmental range, its performance may
vary.
EQUIPMENT CONTAINING LASERS
AR Field Probes (FL/PL Series) and Field Analyzers (FA
Series) are Class 1 laser products containing embedded
Class 4 lasers. Under normal use, the laser radiation is
completely contained within the fiber optic cables and
poses no threat of exposure. Safety interlocks ensure that the laser is
not activated unless the cables are properly connected. Always
exercise caution when using or maintaining laser products. Do not
view directly with optical instruments.
RF ANTENNAS
•
This equipment (antenna or antenna assembly) may be heavy,
requiring two persons to lift. Use caution when installing or
removing unit. Follow all equipment setup and lifting instructions
specified in this document.
• Ensure connectors are appropriate for intended operation.
Connectors are specified in the user manual and product
specification sheet.
• Do not exceed the maximum RF input level stated in the
specifications. Refer to the user manual and product specification
sheet to determine the applicable RF levels.
• Excessive RF input could damage the equipment or connectors,
causing safety hazards.
• When in operation, the RF voltages on the antenna elements can
be hazardous. Do not come into contact with the antenna or
elements when the RF input connector is connected to a live RF
source.
•
To avoid injury to personnel and accidental damage to power
amplifier or antenna, disable the RF output of power amplifier
before connecting or disconnecting the input connection to the
antenna.
• Perform periodic inspections of antenna and field probe systems
to verify calibration due date, proper operation, and overall
condition of equipment.
RACK MOUNTED TWT MODELS
Some TWT models are supplied without the removable enclosure
offered for benchtop use. These rack-mountable models may be
supplied with either carry handles or slides and front handles installed.
Follow all lifting instructions specified in this document and
installation instructions supplied in the TWT user manual.
LIFTING INSTRUCTIONS FOR AR EQUIPMENT
Because most products must be handled
during distribution, assembly and use, the
risk of serious injury due to unsafe
product handling should be a fundamental
consideration of every user. An
authoritative guideline for eliminating
unwarranted risk of injury caused by
lifting is provided by the NIOSH Work Practices (Publication #94-
110) available at:
https://www.cdc.gov/niosh/docs/94-110/pdfs/94-110.pdf .
In general, observe the following guidelines for lifting a weight of 50
lb or more:
• Use lifting eye (for floor standing) or side handles (table top) to
lift unit only.
•
Use equipment of adequate capacity to lift and support unit.
•
If using forklift to move unit, be sure forks are long enough to
extend beyond the side of the unit.
