Applications
Inverters for 400 V, 500 V and 690 V are required in the chemical
industry that meet the special demands and requirements of this
industry sector. 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 ter-
minal strip).

Accessories
■
Design
• Compact, modular inverter
• 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) acc. 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)
• Terminal strip acc. to NE37, if fulfilled
• Sine-wave filter integrated in the PM260 Power Modules
(500 V to 690 V)
• A line reactor is not required for the PM260 and PM250 Power
Modules
• PM250 and PM260 Power Modules are capable of energy
recovery
• A series of inverters for the complete voltage and power range
• The integrated or external sine-wave filter permits unshielded
motor cables up to 300 m; shielded motor cables are possible
up to 200 m (carefully observe the max. length of the tempe-
rature sensor cable!)
• An extremely compact overall drive system can be achieved
when using a PM260 Power Module, frame size FSD or FSF
(the line reactor and sine-wave filter are not required, the
chemical industry module is directly snapped onto the Power
Module).

Function
• Thermal motor protection (TMP) using the the PTC thermistor
integrated in the motor (incl. protective separation up to 690 V
line supplies)
• The analog inputs and outputs are electrically isolated
(MW1 to 3)
• Provision of NAMUR terminal strip (-X2; -X3)
