Electrical Safety

The instrument has been designed to protect the operator from potential electrical hazards. This
section describes some recommended electrical safety practices.
Lethal voltages are present at certain areas within the instrument. Internal
maintenance of the instrument should only be performed by a PerkinElmer
service engineer or similarly authorized and trained person. When the
instrument is connected to line power, opening the instrument covers is likely
WARNING
to expose live parts. Even when the power switch is off, high voltages can still
be present. Capacitors inside the instrument may still be charged even if the
instrument has been disconnected from all voltage sources.
The instrument must be correctly connected to a suitable electrical supply. The supply must have
a correctly installed protective conductor (earth ground) and must be installed and checked by a
qualified electrician before connecting the instrument.
Any interruption of the protective conductor (earth ground) inside or outside
the instrument or disconnection of the protective conductor terminal is likely
to make the instrument dangerous. Intentional interruption is prohibited.
WARNING
When working with the instrument:
•
Connect the instrument to a correctly installed line power outlet that has a protective
conductor connection (earth ground).
•
Do not operate the instrument with any covers or internal parts removed.
•
Do not attempt to make internal adjustments or replacements except as directed in the
manuals.
•
Disconnect the instrument from all voltage sources before opening it for any
adjustment, replacement, maintenance, or repair. If afterwards, the opened instrument
must be operated for further adjustment, maintenance, or repair, this must only be done
by a PerkinElmer Service engineer or similarly authorized and trained person.
•
Whenever it is possible that the instrument is no longer electrically safe for use, make
the instrument inoperative and secure it against any unauthorized or unintentional
operation. The electrical safety of the instrument is likely to be impaired if, for exam-
ple, the instrument shows visible damage, has been subjected to prolonged storage
under unfavorable conditions or has been subjected to severe stress during
transportation.
