Special Conditions For Safe Use - Madas XVO/NC Serie Manual Del Usuario

• Cut out power prior to proceeding with wiring;
• According to the plant geometry, check the risk of explosive mixture arising inside the piping;
• If the solenoid valve is installed near other devices or as part of an assembly, compatibility between the solenoid
valve and this other device must be evaluated beforehand.
• Avoid installing the solenoid valve near surfaces that could be damaged by the coil temperature. ATTENTION:
the surface temperature could cause contact burns. If it is installed in a domestic environment, it must not be
accessible to unqualified personnel;
• Provide a protection against impacts or accidental contacts if the solenoid valve is accessible to unqualified personnel.
3.2 - INSTALLATION
• Assemble the device by screwing it, with the due seals, onto the plant with pipes and/or fittings with the right threading to be
connected. Do not use the coil (8) as a lever to help you screw it on, only use the specific tool;
• The arrow, shown on the body (3) of the device, needs to be pointing towards the utility;
• The device can also be installed vertically without prejudicing the correct operation. It cannot be put in
upside down (with the coil (8) pointing downwards);
• During installation, avoid debris or metal residues from getting into the device;
• To guarantee mechanical tension-free assembly, we recommend using compensating joints, which also adjust to the pipe's
thermal dilation;
• If the device is to be installed in a ramp, it is the installer's responsibility to provide suitable supports or correctly sized
supports, to properly hold and secure the assembly. Never, for any reason whatsoever, leave the weight of the ramp only on
the connections (flanged or threaded) of the individual devices;
• In any case, following installation, check the seals on the plant;
• ATTENTION: The coil is provided with a 3m long power supply cable (1). This cable CANNOT be replaced with a
different one. In the event of damage, the part (coil) must be disposed of and replaced with an identical new one; Any repair
(if possible) can only be carried out by the manufacturer;
• In the dangerous zone, wire the ends of the cable with explosion-proof approved equipment (E.g. Terminal box with "E"
protection or increased safety according to EN 60079-7) using the special wire terminals;
• Cable colours
Phase : brown (alternatively black or grey)
Neutral : blue
: yellow/green
• Make sure the connection cables are inserted correctly into the electrical terminal, ensuring they are not crushed and/or
damaged in order to prevent short circuits and interferences.
• Provide a fixed installation ensuring adequate protection against mechanical stress;
• The valve needs to be connected to earth either through the pipe or through other means (e.g. cable jumpers).

Special conditions for safe use

The "X" symbol (positioned at the end of the protection mode) indicates particular conditions of use:
• Clean the product regularly to prevent dust from building up;
• The valve must be installed in places at a low risk of mechanical impact;
• Respect the number of cycles/h indicated in 2.0 (Technical Data). Contact the technical department for different times/cycle;
• Minimum bending radius of the cable = 4 Ø; minimum installation temperature -35°C;
• The equipment must be protected against the effect of lightning discharges;
• Sparks caused by impact or friction on light metals can cause sources of ignition, therefore tools with corroded surfaces
must not be used under any circumstances (e.g. for adjustments, maintenance, etc.);
• Protect the product from impact or friction caused by other objects;
• Periodically check the integrity of the dissipative surface treatment of the coil and connector;
• Do not install in environments where the product is in direct contact with corrosive gases, chemicals, salt water, water or
steam (C3 or medium degree of environmental pollution). Contact the technical department for any other application, for
the compatibility analysis;
