(*): 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.

Connections
Type of connection Cross-sections Maximum current
fi xed screw for cables from 0.5 to 2.5 mm
2
12A
plug-in for screw blocks
spade with crimped contact
wire cross-section for probes and digital inputs: 0.25 to 2.5 mm2 (from 20 to 13 AWG)
wire cross-section per power supply and loads: 1.5 to 2.5 mm2 (from 15 to 13 AWG)
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.
