1) These control boxes are designed so that they can be used safety in hazardous areas of Zone 1 and 2.

2) Type of protection : Exde II CT5. These control boxes can be used in hydrogen, acetylene and carbon disulfide gas atmospheres.

3) Boxes have a dustproof and jet-proof structure which meets the requirements of IEC standards, Degree of protection IP65.

4) Boxes are made of stainless steel with high corrosion and weather resistance so they can safely be used outdoors.

5) Their high-luminance LED pilot lamps are bright and highly visible and guarantee a long life without the need for maintenance.

6) The large pushbutton switches allow easy operation.7) The hinged box provides easy access for wire connec-

tion work or maintenance.

Precautions in cable connection◦ Since the control box does not house any terminal block,

connect the lead wire directly to the terminal of each unit to be housed.

◦For combinations of units other than standard, consult us.◦ A control box with a junction terminal block in which

standard wire connection between each unit and the terminal block is made is also available upon request.

Installation◦ Carry out installation according to the IEC standards.◦ For Division 1 areas, use cables or flameproof metallic

conduits for wiring. For Zone 2 areas, use cables or increased safety metallic conduits. With metallic conduits, apply vertical or flexible type sealing fitting close to the control box entries.

◦ For the anchor bolts for the stand type, use commercially availabale bolts.
