Electrical Safety - PerkinElmer 200A Series User Manual

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. Installation and internal maintenance of the
instrument should only be performed by a PerkinElmer Service
Representative or similarly authorized and trained person.
WARNING
When the instrument is connected to line power, opening the instrument
covers is likely 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 or 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 Representative.
• 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 example, the
instrument shows visible damage; has been subjected to prolonged storage under
unfavorable conditions; or has been subjected to severe stress during transportation.
