Safety instructions
Electrical devices may only be mounted and connected by electrically skilled persons.
Serious injuries, fire or property damage possible. Please read and follow manual fully.
Danger of electric shock. Always disconnect before carrying out work on the device or load.
Danger of electric shock. Device is not suitable for disconnection from supply voltage. The load
is not electrically isolated from the mains even when the output is switched off.
Risk of destruction of the dimmer and load if the set operating mode and load type do not
match. Set the correct dimming principle before connecting or exchanging the load.
Fire hazard. For operation with inductive transformers, each transformer must be fused on the
primary side in accordance with the manufacturer's instructions. Only safety transformers ac-
cording to EN 61558-2-6 may be used.
These instructions are an integral part of the product, and must remain with the end customer.
The connected load and dimmer quality on LED lamps are dependent on the type of lamp
and installation conditions. The connected load of the specified values could vary. We
cannot assume any guarantee for proper function, dimming results and dimming quality.

- Page 5 Universal dimming actuator, 1-gang, 2-gang, 4-gang ￭ Operate the output with the button ON/n or the button OFF/o. Short: switch on/off. Long: dim brighter/darker. Release: Stop dimming. The LEDs ON/n and OFF/o indicate the status. Short-term manual operation: After running through all of the outputs the device exits manual mode after another brief press.
- Page 6 Universal dimming actuator, 1-gang, 2-gang, 4-gang Connecting lamp load Figure 4: Dimming actuator – Connection example Do not exceed permissible total load including transformer power dissipation. Operate inductive transformers with at least 85% nominal load. Mixed loads with inductive transformers: ohmic load max. 50%. HV-LED lamps and compact fluorescent lamps: Only connect lamps of one manufacturer and of the same type on the same output.
- Page 7 Universal dimming actuator, 1-gang, 2-gang, 4-gang Choose power boosters that are suitable for the dimmer and load. Program the operation with Universal power extensions in the device or – with devices up to version V01 – set the maximum brightness to 90 %. For more information please see instructions of the re- spective power pack.
