1.2 SAFETY PRECAUTIONS
Listed are several safety precautions which
must be observed during installation and
operation. Aeroflex assumes no liability for
failure to comply with any safety precautions
outlined in this manual.
1.2.1 Complying with Instructions
Installation/operating personnel should not
attempt to install or operate the Test Set
without reading and complying with all
instructions contained in this manual. All
procedures must be performed in exact
sequence and manner described.
1.2.2 Grounding Requirements
To minimize shock hazard, all equipment
chassis and cabinets must be connected to
electrical ground. All Aeroflex test sets are
equipped with a standard three-prong power
cable which must be connected to a properly
grounded three-prong wall receptacle. It is the
customer's responsibility to:
● Have a qualified electrician check wall
receptacle(s) for proper grounding.
● Replace any standard two-prong wall
receptacle(s) with properly grounded three-
prong receptacle(s).
WARNING: DO NOT USE A THREE-
PRONG TO TWO-PRONG
ADAPTER PLUG. DOING SO
CREATES A SHOCK
HAZARD BETWEEN THE
CHASSIS AND ELECTRICAL
GROUND.
1.2.3 Operating Safety
Due to presence of potentially lethal voltages
within Test Set, operating personnel must not
remove top or bottom covers at any time.
1.2.4 CAUTION and WARNING Labels
Extreme care should be exercised when
performing any operations preceded by a
CAUTION or WARNING label. CAUTION labels
appear where possibility of damage to
equipment exists and WARNING labels denote
conditions where bodily injury or death may
result.
