(*): Relay not suitable for fl uorescent loads (neon lights, etc.) that use starters (ballasts) with phase shifting capacitors. Fluorescent lamps with electronic controllers
or without phase shifting capacitors can be used, depending on the operating limits specifi ed for each type of relay.
The correct sizing of the power and connection cables between the instrument and the loads is the installer’s responsibility. Depending on the model, the maxi-
mum current at common terminals 1, 3 or 5 is 12 A. If using the controller at maximum operating temperature and at full load, the cables used must be suitable for
operation at least up to 105 °C.
