(*): between the OFF status and the following ON status of the relay at least 1 minute have to elapse.
(**): Relay not suitable for fl uorescent loads (neon lights, ...) that use starters (ballasts) with phase-shift capacitors. Fluorescent lamps
with electronic control devices or without phase-shift capacitors can be used, within the operating limits specifi ed for each type of relay.

the installer has to provide the correct dimensioning of the power supply and cable connection between the instruments and the loads.
Depending on the model, the maximum current in the common terminals 1, 3 or 5 is 12 A. When using the controller at maximum operating
temperature and full load, use cables featuring a maximum operating temperature of 105 °C at least.
