Application
Inverters for 400 V / 500 V and 690 V are required in the chemi-
cal industry that meet the special demands and requirements of
this industry. The essential requirements and demands of the
chemical industry are fulfilled using the SINAMICS G120 series
of inverters supplemented by the CM240NE chemical industry
module (with ATEX-certified PTC evaluation and a NAMUR
terminal strip).
CM240NE chemical industry module
■
Design
•
Isolated analog inputs and outputs in the chemical industry
module (1 setpoint / 2 measured values)
•
Isolated digital inputs and outputs in the Control Unit
•
Protective separation of the motor sensor cable with respect
to the enclosure and other connections using reinforced insu-
lation of the creepage and clearances (rated impulse voltage
12 kV) according to EN 60664 1
•
Certified power disconnection (94/9/EC, ATEX) of the inverter
without main contactor
•
Forced inverter inhibit (EMERGENCY STOP function via STO)
•
NAMUR terminal strip according to NE 37
The CM240NE chemical industry module has the following
interfaces:
1)
Cannot be used with CU250S-2 (must be mounted on a DIN rail).
