Before Applying Power; Keep Away From Live Circuits; Do Not Operate In An Explosive Atmosphere; Do Not Substitute Parts Or Modify Instrument - Raytech mini-ATOS Instruction Manual

1.4 Before Applying Power

Read this manual carefully before operating the system. The instrument is line operated. The
system is designed to be used with either 110VAC or 230VAC 50/60 Hz. The system performs
a self-check each time it is powered on.

1.5 Keep Away from Live Circuits

Operating personnel must not remove instrument covers. Component replacement and internal
repairs must be made by qualified service personnel. Do not replace components or service this
instrument with the power cable connected. To avoid injuries, always discharge circuits,
disconnect power and remove external voltage sources before touching components.

1.6 Do Not Operate in An Explosive Atmosphere

Do not operate the instrument in the presence of flammable gases or fumes.

1.7 Do Not Substitute Parts or Modify Instrument

Because of the danger of introducing additional hazards, do not install substitute parts or
perform any unauthorized modification to the instrument. Return the instrument to a Raytech
service department for service to ensure proper operation and that safety features are
maintained.
Instruments, which appear damaged or defective, should be made inoperative and secured
against unintended operation until they can be repaired by qualified service personnel.

1.8 Do Not Operate in A Condensing Humidity or Under Rain

Operating the instrument in condensing humidity or under the rain can introduce an electric
shock hazard for the user and also can damage the instrument. This instrument is not supposed
to be installed permanently outdoor.

1.9 Always Keep Distance from the Test Object During the Tests

During performing the tests, there may be a hazardous voltage at the terminals of the test
object. Always keep a distance of a minimum of 1.5m from the test object. The unsafe area
must be specified and restricted with barrier tapes or ropes like Figure 1. Enter the area only
when not testing and when the instrument shows that there is no output voltage which is
specified when the green light indicator on the front panel is on.
