Do In order to protect against accidental contact with relay connections at voltages above 42 Veff, the device must be installed in an enclosure (preferably a control panel). It must be impossible to open the enclosure without the aid of a key or tool. AC 230 V cables must be double-insulated against safety extra low-voltage (SELV) cables. DISPOSAL NOTES The controller includes electrical and electronic components and must not be disposed of as domestic waste. Current local legislations must be observed!
