• Unless expressly permitted, never remove the cover or any part of the housing while the product is
in operation. Doing so will expose circuits and components and can lead to injuries, fire or damage
to the product.
• Use suitable overvoltage protection to ensure that no overvoltage (such as that caused by a bolt
of lightning) can reach the product. Otherwise, the person operating the product will be exposed to
the danger of an electric shock.
• The overvoltage protection should limit the magnitude of the overvoltage surge to 1kV between the
any of the power line and ground.
• Any object that is not designed to be placed in the openings of the housing must not be used for
this purpose. Doing so can cause short circuits inside the product and/or electric shocks, fire or
injuries.
• Prior to cleaning the product, disconnect it completely from the power supply. Use a soft, non-
linting cloth to clean the product. Never use chemical cleaning agents such as alcohol, acetone or
diluents for cellulose lacquers.
LED (Light-Emitting diode)
CAUTION!
LED (light-emitting diode) HAZARD. Removing the protective covers and (when
applicable) defeating the interlock(s) may result in exposure to the internal LED. LEDs can burn the
retina, causing permanent blind spots. To ensure safe LED operation:
• Never look directly into the light beam.
• Wear proper eye protection and post a warning sign at the entrance to the laboratory if the LED
protection is defeated for servicing
• Remove jewelry and other items that can reflect a light beam into your eyes or those of others
Do not remove safety labels, instrument protective panels, or defeat safety interlocks.
