MOUNTING & OPERATING INSTRUCTIONS IN STEPS
Before you start mounting the DR speed controller, read carefully “Safety and
Precautions”. Then proceed with the following mounting steps:
1. Switch off the power supply.
2. Mount the controller on a standard 35 mm DIN rail. Pull the locking clip before
you place the unit onto the rail, and then release the locking clip back to its original
position to fix the enclosure to the rail. See Fig. 1 DIN rail locking clip, Fig. 2 Mounting
dimensions and Fig. 3 Mounting position.

5. Set the required output voltage with the help of the potentiometer on the front
cover. Adjust the minimum speed with the trimmer (if necessary). e factory
preset is 100 VAC. See Fig 1.
VERIFICATION OF THE INSTALLATION INSTRUCTIONS
When you switc h on the power supply the LED f or operating indication shown in Fig. 4
should give out constant green light. If this is not the case, check the connections.
