Date of Issue: 2017-06-09

Schedule

EQUIPMENT:

Equipment and systems covered by this certificate are as follows:

The control and distribution box of type Klippon STB… is used as a general purpose connection and junction box that can be equipped

with approved ex-components such as cable glands and terminals for cross-connections of conductors in compliance with the thermal

requirements of the respective temperature class. The enclosure consists of a bottom section and a cover made of stainless steel. The

cover is locked by fastening screws; sealing is provided by means of a silicone gasket. The control and distribution box can be used for

the types of protection “e” (increased safety) and “t” (dust ignition protection by enclosure) in potentially explosive gas and dust

atmospheres of zone1 and21. If all electrical circuits are intrinsically safe with level of protection “ia”, the box can also be used in

zone0.

These values are maximum values. The actual values are determined by the installed components / terminals. The manufacturer

specifies the rated values in the context of these maximum values and ensures compliance with the maximum surface temperature of

the equipment and the permissible operating temperature of the components / terminals. The actual rated values are indicated on the

individual marking plates and in the manufacturer's instructions.
