PP500 LED lighting controllers - User Manual

Safety
Read this before using the PP500. 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 PP500 is mounted correctly (see
Section 6,
Mechanical fixing
), and that you do not exceed any of the
ratings for the unit (see ).
At its maximum ratings, the PP500'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 PP500 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 PP500 for about 15 seconds.
The PP500 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 PP500 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

60335-1, IEC 61010-1, IEC61558-1,-2,-16. The PSU may also be
approved to equivalent or superior safety standards.
Any energised conductors derived from mains electricity must also have
Safety Extra Low Voltage (SELV) output. Refer to for allowable voltage lim-
its.
At maximum ratings the temperature of the enclosure can exceed 75°C.
Therefore, either all cabling must be rated to at least 100°C, or all cabling
must be additionally insulated by an appropriately rated heat resistant
sleeve or prevented from touching the metal enclosure of the controller, or
its heatsink where fitted.
Power supply cabling to the controller must be rated to at least 4A.
The cabling from the channel output to the load must be rated higher than
the maximum channel output current.
If the controller is setup incorrectly, or in the event of failure, the energy
provided by the power supply to the controller may become directly con-
nected to any or all output channels. You must consider this during install-
ation, and if necessary, provide adequate protection.
The DC power supply to controller must be externally fused to 4A using a
slow blow fuse (T4AH, 50V).
The installer must provide a clearly marked, nearby and easily accessible
switch as part of the installation to allow the controller to be disconnected
from its energy source on both power conductors.
Transients caused by inductive loads must be suppressed externally to
the PP500.
Warning:
This is a Class A product. Its use in residential areas may cause
radio interference, and such use should be avoided unless special
measures are taken by the user to restrict emissions to a level that allows
the reception of broadcast transmissions.
2.3
General
The PP500 must not be used in an application where its failure
could cause a danger to personal health or damage to other
equipment.
If the equipment is used in a manner not specified by the manufacturer,
the protection provided by the equipment may be impaired.
2.4
Installation guidance
(disclaimer)
This information is for guidance only. Installers must perform their own risk
assessment specific to each installation. While Gardasoft Vision Ltd has
taken every care in the preparation of this advice, Gardasoft Vision Ltd
accepts no liability for damages of any kind except those required by law.
Deliberate acts of endangerment and vandalism are not covered by this
document and must be considered by the installer.
