Special Conditions For Safe Use - Madas JW-1 Serie Manual Del Usuario

• With outdoor installation, it is advisable to provide a protective roof to prevent rain from damaging the electrical parts of the device.
• Prior to carrying out any electrical wiring operations, make sure that the main voltage matches the supply voltage indicated
on the product label;
• 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;
• The solenoid valve is suitable for installation in places at low risk of mechanical impact. 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 (11) as a lever to help you screw it on, only use the specific tool;
• The arrow, shown on the body (4) 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 (11) 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 tightness of 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 with an antistatic cloth to prevent dust from building up and the formation of electrostatic charges;
• 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;
• Keep ambient humidity under control to minimise the formation of electrostatic charges;
• Protect the coil from direct air draughts that could cause the accumulation of electrostatic charges;
• Touch only with an electrically insulated object.
• 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;
• 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;
