Notes
Security
DANGER
• The device must be mounted and commissioned by an authorized electrician.
• A safety disconnection of the device must be possible.
• The device must not be opened.
• Use only loads that allow dimming operations.
• Conventional transformers may be used. If they comply with the relevant standards and
contain a thermal fuse.
• For planning and construction of electric installations, the relevant guidelines, regulations
and standards of the respective country are to be considered.
• Connecting inductive loads together with capacitive or resistive loads to the same
dimmer output is not permitted and leads to damage or destruction of the universal
dimmer!
• Dimming of inductive loads with trailing edge mode could damage the device.

Note:
• In case of exceeded temperature, overload, or short circuit, the dimmer turns off the
output. Restart the dimmer by using an “on” or “dimming value > 0” command.
• In case of overtemperature, wait at least 1 minute and then restart the dimmer (cool-
ing down time).
Note:
• Trailing edge mode occurs sometimes with a limited dimming range and an irregular
dimming curve, but with less power-loss. Manual adjustment of control mode (trailing
/leading edge) or min./max. dimming value is possible by Software.
