ConnECtIons
The typical power supply installation requires the use of the stand-alone Vimar universal
master dimmer in the configuration described in fig. 1.
The stand-alone Vimar master dimmers which can be used to control the dimmerable LED
electronic power supply are:
• 1M universal rocker master dimmer: art. art. 20135-19135-16559-14135;
• 1M universal rotary master dimmer + button: art. art. 20136-19136-16603-14136.
• The dimmer connection should be made together with a fuse carrier with a fuse with a high breaking
capacity type F2.5AH250V as shown in the diagrams..

! Important: With the art. 01874 the LED modules must be connected only in parallel.
The LED dimmerable electronic power supply can also be controlled by a switch between the
phase and the controlled input (fig. 2). In this case it is only possible to switch ON/OFF at maxi-
mum brightness of the LED module connected to the power supply.
