3.1 INSTALLATION RULES AND SECURITY
3.2 Protect the device against the direct exposure to the sun.
3.3 Avoid arranging the device in the proximity of or in direct contact with any source of heat and electromagnetic field. Connect
the device on supply lines different from those used for motor drives or other devices that may cause some noise on the
net.
Not security equipment.
3.4 Fix the device on the wall at minimum 60 cm from the floor.
3.5 The access to the device to adjust operating parameters have to be done by person with appropriate skills.
3.6 Before acting on the device for any operation, check for safe conditions. For electrical operations never forget to disconnect
the power supply, wait for 30 seconds for the internal capacitors discharge before opening. At the end of the operations
close the device to restore the protection degree before powering again.
3.7 In case of faulty that does not depend only the fuse, switch off immediately the supply voltage and contact the supplier.
3.8 One time in a month or more frequently if necessary verify if there is dust on the enclosure of the device and remove it if it is
present by using wet cloth.
3.9 For supply voltages, cabling and voltages applicable to the relay contacts, follow the current rules
3.10 For all input control signals to the Timer (D1a, D5, D6,...) use anti-flame wires with a minimum section of 0.5 mm².
3.11 For the electrical connection of the supply voltage and filter cleaning electrovalves use anti-flame wires with a minimum
section of 0.75 mm². For output relay contacts use anti-flame wires with a minimum section of 1.5 mm2.
3.12 The lack of application of existing rules and standards of installation and safety exonerate the manufacturer of
responsibility.
3.13 For the output signal 4÷20 mA related to dP use anti-flame shielded wire with minimum section of 0,5 mm². (Option on
request. Code: C11a)
3.14 Do not connect to earth the common of the electrovalves (see electrical wiring diagram).
