3.3.4 CABLE CONSIDERATIONS
It is the customer's responsibility to design and install the PowerPro ELXA supply and distribution circuits,
and provide all the external fuses, switchgear and cables required to connect the cabinet's AC INPUT and
SI OUTPUT supplies. The information provided in this section should assist you in the planning and
preparation of the power cabling.
The AC INPUT terminals should be connected to a utility mains LV-switchgear panel and protected by a
circuit breaker or fused isolator.
Similarly, the SI OUTPUT terminals should be connected to the load equipment via a suitably protected
load distribution panel.
The Maximum recommended output circuit breakers sizes tested as per EN50171 are specified in the
following table.
3.3.5 INRUSH CURRENT
Special Consideration should be taken when installing luminaires with very high inrush
characteristics.
The Inrush Current of LED Luminaires is determined by the driver (s) and is not proportional to
the luminaire wattage or running current, LED luminaire inrush currents can be as high as 400
times the running current for a very short period of time.
Further information regarding LED inrush currents can be found by accessing the "LIA Technical
Statement LIA TS35" from the LIA website (www.thelia.org.uk).
The table below provides some details regarding the maximum recommended inrush currents
for luminaires:
If higher inrush levels are expected KOHLER can provide Inrush Current Limiter for LED lighting
Drivers.
Rated at maximum 16A continuous power they can be installed within lighting distribution
panels.
