Safety Measures
This paragraph explains the safety procedures which should be followed under all circumstances not to counter
the risk of an accidental electric shock, damage to the equipment or a major operation interruption.
Power-on
WARNING
• Before power-on: The MS2665C/67C/68C spectrum analyzer must be connected to
protective ground.
If the power is switched on without taking this countermeasure,
there is a risk of receiving a accidental electric shock. In addition, it
is essential to check the power supply voltage. If an abnormal volt-
age that exceeds the specified value is input, there is accidental risk
of damage to the MS2665C/67C/68C and fire.
• During power-on To maintain the MS2665C/67C/68C, sometimes it is necessary to
make internal checks and adjustments with the covers removed
while power is supplied. Very-high, dangerous voltages are used in
the MS2665C/67C/68C, if insufficient care is taken, there is a risk of
a accidental electric shock being received or of damage to the
equipment. To maintain the MS2665C/67C/68C, request service
by a service personnel who has received the required training.
In the following, special notes on safety procedures are extracted from sections other than Section 2.
To prevent accidents, read this section together with the related sections before beginning operation.
