RTxxx LED lighting controllers - User Manual
limits 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 current 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
Section 13, Reference
information
for allowable voltage limits.
At maximum ratings the temperature of the enclosure can exceed 65°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 5A or 10A
(RT8xxF).
The cabling from the channel output to the load must be rated higher than
the maximum channel output current.
If the controller is set up incorrectly, or in the event of failure, the energy
provided by the power supply to the controller may become directly
connected to any or all output channels. You must consider this during
installation, and if necessary, provide adequate protection.
The DC power supply to controller must be externally fused to 5A or10A
(RT8xxF) using a slow blow fuse (T5AH, 50V or T10A, 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 RTxxx.
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 RTxxx must not be used in an application where its failure could be 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.
