EC-Type Certificate Installation Instructions:

Cable Connection

The cable entry device shall be certified in type of explosion protec-

tion flameproof enclosure “d”, suitable for conditions of use and cor-

rectly installed. For ambient temperatures over 70°C, cable and cable

glands suitable for at least 90°C shall be used.

Conduit Connection

An EEx d certified sealing device such as a conduit seal with setting

compound shall be provided immediately to the entrance of the valve

housing. For ambient temperatures over 70°C, the wiring and setting

compound in the conduit seal shall be suitable for at least 90°C.

Note: ATEX units only: The temperature class is determined by the

maximum ambient and or process temperature. Units are intended

to be used in ambient of -20°C) Tamb )75°C. Units may be used in

process temperatures up to 105°C providing the enclosure and

switch body temperature do not exceed 75°C. The standard

Temperature Class is T6 Process Temp )75°C. Alternate

Temperature Class of T5 Process Temp )90°C and 115°C (T4)

Process Temp )105°C are available consult factory.

All wiring, conduit and enclosures must meet applicable codes for

hazardous areas. Conduits and enclosures must be properly sealed.

For outdoor or other locations where temperatures vary widely, pre-

cautions should be taken to prevent condensation inside switch or

enclosure. Electrical components must be kept dry at all times.

CAUTION: To prevent ignition of hazardous atmospheres, discon-

nect the device from the supply circuit before opening. Keep assem-

bly tightly closed when in use.

MAINTENANCE

Inspect and clean wetted parts at regular intervals. The cover should

be in place at all times to protect, the internal components from dirt,

dust and weather and to maintain hazardous location ratings.

Disconnect device from the supply circuit before opening to prevent

ignition of hazardous atmosphere.
