Installation Manual
This option allows for setting a desired brightness level for the cab by adjusting potentiometer located on
the Dimming board. There is also a connection on the board for an optional remote potentiometer
(customer provided) so brightness levels can be manually adjusted without having to access the car top.
The AC voltage input of the power supply (Brown = LINE, Blue = NEU) is left free for the customer to
decide how to connect. Figure 8 - CabLite ECO with Dimming Wiring shows wire nuts.
The 24VDC power supply output is prewired at the factory to the Dimmer Board. The Dimmer board has
a 12” cable prewired to the LIGHTING Output of the Dimmer board. It has a two pin connector for easy
connection to the 8’ cable of the first downlight.
