Uncover The Inverter Vents; Mx2 Control Wiring Quick Reference - Omron MX2 User Manual

Step-by-Step Basic Installation
Breaker, MCCB
or GFI
Power source,
3-phase or
1-phase, per
inverter model
Intelligent inputs,
7 terminals
NOTE:
For the wiring of intelligent
I/O and analog inputs,
be sure to use twisted
pair / shielded cable.
Attach the shielded wire
for each signal to its
respective common
terminal at the inverter
end only.
Input impedance of
each intelligent input is
4.7 kΩ
Thermistor
GND for logic inputs
Freq. Meter
Volt. Meter
Analog reference
GND for analog signals

After mounting and wiring the inverter,
remove any covers from the inverter hous-
ing. This includes material over the side ven-
tilation ports.
Make sure the input power to the inverter is
OFF. If the drive has been powered, leave it
OFF for ten minutes before continuing.
