MOUNTING REMARKS
1. Do not mount dimmers in a close proximity to each other (if there is a possibility, keep a distance
of minimum 15 cm between RDP-21 devices). Particularly, avoid installation of one dimmer over
the another.
2. The RDP-21 receiver cooperates with incandescent light sources and halogen lamps 230 V AC,
12 V light sources supplied by an electronic transformer (ELV) or a magnetic transformer (MLV)
and selected dimmable LEDs and fluorescent CFL lamps.
3. Do not connect loads greater than recommended.
4. Minimum load connected to the output of a dimmer is about 15 W.
5. In case a magnetic transformer is connected to a dimmer's output, then it is necessary to load at
least 50% of the transformer's nominal power.
6. In case of a dimmer and magnetic transformer cooperation, a noisy operation of the transformer
is noticeable at a certain degree of control (to a large extent it depends on the quality and power
of the transformer). For this reason, the use of electronic transformers (ELV) is recommended.
7. It is not recommended to connect more than one transformer to the output of the RDP-21 dim-
mer (it refers to both electronic and magnetic transformers).
8. It is necessary to increase the minimum level of lighting while using dimmable fluorescent lamps
(CFL). It is possible to change this parameter by means of a mobile application in cooperation
with the EXTA LIFE controller. Increasing the minimum lighting level protects the fluorescent
lamps (CFL) against switching off, if they are dimmed to a minimum (if the dimmer output voltage
is too low). The same problem also applies to some LEDs.
9. In case of dimmable LEDs and compact fluorescent lamps, the effect of light incandescence or
flicker of the switched off light source may occur. In some situations, a limited lighting luminous
flux intensity adjustment can also occur. It depends on the structure of used light bulbs and their
nominal power.
10. During mounting, make sure the receiver is not exposed to direct water and operation in an
increased humidity environment. The mounting ambient temperature range should be within the
range from -10 to + 55 °C.
11. The RDP-21 receiver is designed to be mounted indoor. In case the receiver is mounted outdoor,
it must be placed in an additional hermetic casing.
12. Monostable or bistable push-buttons can be connected to the IN input. The dimmer cooperates
only with monostable push-buttons. By default, the input is adapted to cooperate with mon-
ostable push-buttons. The use of bistable push-buttons requires a configuration change of the
dimmer. The above is done by means of a mobile application in cooperation with the EXTA LIFE
controller.
13. In case of monostable push-buttons, there is a connection possibility of several push-buttons to
the IN input - it allows for an independent control of this device from several places.
