2.5.2 Circuit types with three-phase motors
The three-phase motor's stator winding can be connected in a star or delta
circuit as per the rated operational data on the rating plate.

DE1-342D1… (U
LN
= 400 V): Motor in star connection
2.5.3 Connecting EX motors
The following aspects must be taken into account when connecting
explosion-proof motors:
•
A DE1 variable speed starter can be installed inside an explosion-proof
enclosure within the hazardous location or inside a control panel outside
the hazardous location.
•
All applicable industry-specific and country-specific regulations for
hazardous locations (ATEX 100a) must be complied with.
•
The specifications and instructions provided by the motor's
manufacturer with regard to operation with a variable speed starter –
e.g., whether motor reactors (dV/dt limiting) or sine filters are required –
must be taken into account.
•
Temperature monitors in the motor windings (thermistor, thermo-Click)
are not to be connected directly to DE 1 variable speed starters but must
be connected via an approved trigger apparatus for EX areas i.e. EMT6.
