EPS 18 ATEX 1 202 X, EPS 18 ATEX: 1 202 X
It is not permissible to operate groups of motors connected to the converter. The rated
converter current may correspond as a maximum to twice the rated motor current. It is only
permissible to operate the motor with a SINAMICS converter or a converter that is
comparable. When commissioning the system, with reference to the rated voltage (UN) of
the winding insulation, carefully ensure that no converter-related overvoltages with a peak
value exceeding (1.1 * √2 * UN) occur at the terminals of the electric motor. If anti-
condensation heating is used, then an interlock circuit must ensure that the anti-
condensation heating can only be operated when the motor is shut down. If the three-phase
motor is cooled using an external fan, then it must be carefully ensured that the motor can
only be operated when the external fan is switched on.
