H International Standards (EC Directives and UL/cUL
Standards)
The 3G3MV Inverter meets the EC Directives and UL/cUL standard requirements for
worldwide use.
Classification Applicable standard
EC Directives
EMC directive EN50081-2 and EN50082-2
Low-voltage directive prEN50178
UL/cUL UL508C
H Compatible with CompoBus/D and RS-422/485
·Supports RS-422 and RS-485 communications conforming to the MODBUSCommu-
nications Protocol, thus making it possible to easily constructnetworks with the use of
the Protocol Macro or ASCII Unit mounted on an OMRON SYSMAC PC. The MOD-
BUS Communications Protocol is a trademark of AEG Schneider Automation.
·Connects to the 3G3MV-PDRT1-SINVCompoBus/DCommunicationsUnit. Aremote
I/O function for CompoBus/D communications is available to the 3G3MV Inverter,
which ensures ease of communications just like standard I/O communications.
Furthermore, CompoBus/D communications conform to the DeviceNet communica-
tions protocol for open networks, thus allowing construction of multi-vendor networks
in which other companies’ devices can coexist.
Note ModbuscommunicationandCompoBus/Dcommunication cannot beperformed
simultaneously. It is necessary to select the type of communication required.
H Handles a Variety of I/O Signals
Handles a variety of I/O signals over a wide application range as described below.
·Analog voltage input: 0 to 10 V
·Analog current input: 4 to 20 or 0 to 20 mA
·Pulse train input: 0.1 to 33.0 kHz
·Multi-function analog output or pulse train output is selectable as monitor output
H Suppression of Harmonics
Connects to DC reactors, thus suppressing harmonics more effectively than conven-
tional AC reactors.
