Safety
Read this before using the PP610. Always observe the following safety
precautions. If in doubt, contact your distributor or Gardasoft Vision. The
following symbols mean:
Warning:
Read instructions to understand possible hazard
Warning:
Surface may get hot.
Warning:
Possible hazardous voltage.
Where these symbols appear in the manual, refer to the text for
precautions to be taken.
2.1
Heat
Ensure the PP610 is mounted correctly (see
),
and that you do not exceed any of the ratings for the unit (see
).
At its maximum ratings, the PP610'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 PP610 produces high energy pulses. Take care to connect the
outputs correctly and protect the output wiring and load from any short
circuits. When switched off, energy remains stored in the PP610 for about
15 seconds.
The PP610 does not have complete tracking isolation of inputs and
outputs, 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 PP610 must provide
double insulation/reinforced isolation from mains electricity and protected
against short circuits and overloads. We recommend using a PSU that lim-
its its output current to the appropriate rating of the controller by design,
by setting the current limit on the supply (if possible), or through over cur-
rent protection. The PSU should be approved to either IEC 60950-1, IEC
