Mounting instructions

The series terminal blocks are suitable for use in enclosures in atmospheres with combustible

gases and combustible dust. For combustible gases these enclosures must satisfy the

requirements according to EN 50014 and EN 50019. For combustible dust these enclosures

must satisfy the requirements according to prEN 50281-1-1 .

At ambient temperatures from -50

up to +40

and based on the self-heating, if used at

the above mentioned rated current, the series terminal blocks may be used in electrical

apparatus, e.g. junction and connection boxes, for temperature class T6.

If mounted in apparatus of temperature classes T1 up to T5, the highest temperature of the

insulating material Wemid shall not exceed the value of 100

and the insulating material

PA 66 shall not exceed the value of 80

DC.

Regarding the use of cover sheets, separating plates and end supports the instructions of the

manufacturer must be followed.

In combination with other terminal blocks series and sizes and if other accessories are used

the applicable creepage distances and clearances shall be met.

If smaller cross sections as the rated cross section are used, the belonging lower current has

to be laid down in the EC-Type Examination Certificate of the complete apparatus.

Routine test

According to EN 50019, Clause 7.lob in combination with Clause 6.1, a dielectric strength

test has to be carried out.
