Setting Up the ELx800
Operating Environment
The ELx800™ is designed to operate optimally when installed on a level surface in an
area where ambient temperatures remain between 18°C (64°F) and 40°C (104°F). The
reader is sensitive to extreme environmental conditions, and these conditions should
be avoided:
•
Excessive humidity: Condensation directly on the sensitive electronic
circuitry can cause the instrument to fail internal self-checks.
•
Excessive ambient light: Bright sunlight or strong incandescent light can
reduce the linear performance range of the instrument.
•
Dust: Optical density readings may be affected by extraneous particles (such
as dust) in the microplate wells. A clean work area is necessary to ensure
accurate readings.
Electrical Connections
Caution! Power Supply. Only use the specified power supply to
ensure proper operation of the unit. The ELx800 has a universal
24-VDC, 2.1 A power supply that functions from 100 to 240 V~
(± 10.0%) @ 50 to 60 Hz without external switching.
Never use a two-prong plug adapter to connect primary power to
the ELx800 power supply. Use of a two-prong adapter disconnects
the utility ground, creating a severe shock hazard. Always connect
the power supply cord directly to a three-prong receptacle with a
functional ground.
1. Connect the power cord to the external power supply.
2. Plug the rounded end of the power supply line cord into the power supply
jack on the rear of the instrument.
3. Tighten the knurled nut on the power supply outlet to ensure that the plug
does not pull out.
4. Plug the 3-prong end of the power cord into an appropriate power
receptacle.
Warning! Power Rating. The ELx800 power supply must be
connected to a power receptacle that provides voltage and current
within the specified rating for the system. Use of an incompatible
power receptacle may produce electrical shock and fire hazards.
