Installation Requirements
Electrical Requirements
Power lines within the laboratory should provide at minimum, three-wire single phase power
with one wire neutral/ground. Provision of three-phase service to the laboratory is desirable,
since electrical service may be required for larger instruments.
For electrical safety, suppression of electromagnetic interference and proper performance, this
instrument should be operated from a supply source that incorporates a third wire protective
grounding which conforms to local codes and ordinances.
Power lines reserved for instrument use within the clinical laboratory shall have adequate
reserve capacity. Normal contemplated loading should not exceed 50% of nominal capacity to
allow for start-up loads and the addition of new instruments.
Power Outlets
All single-phase electrical outlets to which instruments are to be attached must provide
standard 3-prong receptacles war-ranted by the manufacturer to the expected power demand.
All receptacles must be properly connected to the power line ground. The use of extension
cords or of multiple outlet adapters is prohibited. Bad practice in these regards can be a source
of poor electrical contacts that are likely to counteract the specified grounding system. The
use of such cords and adapters also provides a potential source of erratic instrument
performance or of shock hazards.
Power outlets, each with two to four receptacles, should be placed every
0.5 to 1.0 m in
instrument usage areas. As an alternative, power strips may be installed. Receptacles shall be
at least 8 cm above the counter top to protect against liquid spills.
Adjacent outlets or power strips should be connected to different “hot lines” from the main
supply. The outlets should be labeled so the same code appears on all outlets to the same hot
line.
Equipment that operates intermittently and thereby creates wide fluctuations in power
demand, such as refrigerators, water baths, and centrifuges, should be plugged into power
