(*): 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 correct sizing of the power and connection cables between the instrument and the loads is the responsibility of the installer.
In the max load and max operating temp. conditions, the cables used must be suitable for operation up to 105°C.
