This certificate is issued as verification that a sample(s), representative of production, was assessed and tested and found to comply with the IEC Standard list below and that the manufacturer's quality system, relating to the Ex products covered by this certificate, was assessed and found to comply with the IECEx Quality system requirements. This certificate is granted subject to the conditions as set out in IECEx Scheme Rules, IECEx 02 and Operational Documents as amended.
This Unit verification certificate is issued as verification that the Apparatus identified on page 1, was assessed and tested and found to comply with the IEC Standard list below. This certificate is granted subject to the conditions as set out in IECEx Scheme Rules, IECEx 02 and Operational Documents as amended.
The apparatus and any acceptable variations to it specified in the schedule of this certificate and the identified documents, was found to comply with the following standards:
As this is a Unit Verification Certificate, no QAR is applicable as this certificate is specific to the items listed by serial number or other unique identification.
The solenoid, types TMEx35 / * and TMEx40 / * , is designed in the type of explosion protection encapsulation "mb" with a terminal box designed in the type of explosion protection increased safety "e". The solenoid is protected against overheating by means of a thermal fuse on the winding.
AC/DC 24 V ± 10%
AC/DC 48 V ± 10%
AC/DC 110 V ± 10%
AC 230 V/DC 200 V ± 10%
The following maximum ambient, equipment or media temperatures Tmax shall be considered for temperature class T5:
The following maximum ambient, equipment or media temperatures Tmax shall be considered for temperature class T4:
- The electrical protection of solenoid shall prevent the prospective short circuit current to exceed 1500 A.
- The solenoid shall not be exposed to mechanical damage. If its installation presents risk of mechanical damage, it shall be additionally mechanically protected.
- The maximum ambient temperature is defined by the maximum allowed temperature of the cable gland and the thermal stability of the cable. The selection of the cable and the cable gland shall be based on the notion that the temperature of the cable gland and the cable may exceed the ambient temperature by up to 25 K.
- If the solenoid is installed in explosive gas atmospheres of group IIC, it is necessary to prevent electrostatic charges of the enclosure. The enclosure may be rubbed only with a damp cloth.
