Ground the Instrument
To minimize shock hazard, the instrument is equipped with a 3-conductor AC power
cable. Plug the power cable into an approved 3-contact electrical outlet or use a
3-contact adapter with the grounding wire (green) firmly connected to an electrical
ground (safety ground) at the power outlet. The power jack and mating plug of the
power cable meet Underwriters Laboratories (UL) and International Electrotechnical
Commission (IEC) safety standards.
Ventilation
The instrument has ventilation holes in its side covers. Do not block these holes when
the instrument is operating.
Do Not Operate in an Explosive Atmosphere
Do not operate the instrument in the presence of flammable gases or fumes. Opera-
tion of any electrical instrument in such an environment constitutes a definite safety
hazard.
Keep Away from Live Circuits
Operating personnel must not remove instrument covers. Refer component replace-
ment and internal adjustments to qualified maintenance personnel. Do not replace
components with power cable connected. To avoid injuries, always disconnect power
and discharge circuits before touching them.
Child Safety
This equipment is not suitable for use in locations where children are likely to be pres-
ent.
Do Not Substitute Parts or Modify Instrument
Do not install substitute parts or perform any unauthorized modification to the
instrument. Return the instrument to an authorized Lake Shore Cryotronics, Inc. rep-
resentative for service and repair to ensure that safety features are maintained.
Cleaning
Do not submerge instrument. Clean only with a damp cloth and mild detergent. Exte-
rior only.
Desktop Installation
When installing the instrument in a desktop environment, ensure it is mounted on a
flat, level surface.
