Safety
Read this before using the VTR4. Always observe the following safety precautions. If
in doubt, contact your distributor or Raytec. The following symbols mean:
Warning: Read instructions to understand possible hazard
Warning: Surface may get hot.
Warning: Possible hazardous voltage.
2.1
Heat
Where these symbols appear in the manual, refer to the text for precautions to
be taken.
Ensure the VTR4 is mounted correctly (see Section 5, Mounting the VTR4), and
that you do not exceed any of the ratings for the unit (see Section 10, Reference
information).
At its maximum ratings, the VTR4’s enclosure can exceed 75°C which is
sufficient to cause a burn if touched. Place in a position where personnel
cannot accidentally touch it and ensure there is a free flow of air around the
unit.
2.2
Electrical
The VTR4 does not have complete electrical isolation of inputs (including
triggering and communications ports), therefore, please observe the following
guidance:
Computer equipment that is connected to the communication or trigger ports
must be internally powered or separated from mains electricity by double
insulation/reinforced isolation or be approved to IEC 60950-1 standard. All
other equipment connected to the triggers or other ports must also have
double insulation/reinforced isolation protection from the mains supply.
The Power Supply Unit (PSU) used to energise the VTR4 must provide double
insulation/reinforced isolation from mains electricity and protected against
short circuits and overloads. The PSU should be approved to either IEC 60950-
1, IEC 60335-1, IEC 61010-1, IEC61558-1,-2,-16. The
PSU may also be approved to equivalent or superior safety standards.
