Special Conditions For Safe Use - Madas JV-1 Guia De Inicio Rapido

• 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;
