Wiring For Main Circuit Terminals - Omron MX2 Series User Manual

Precautions for Correct Use
The Multi-function Relay Output (MA, MB) Function Selection (C026) is, by default, set to 05
(AL: Alarm signal). However, this default data is based on different alarm output specifications
from those of the previous models (3G3 V Series).
The table below shows the relationship between the relay output status when the inverter input
power supply is ON/OFF and the Multi-function Relay Output (MA, MB) Operation Selection
(C036) setting. Select the parameter setting appropriate to the sequence of your inverter
according to this table.

01 (Default data)
Note Set C036 to 00 to have the same relay output status as with the previous model (3G3 V Series).

Wiring for Main Circuit Terminals

Precautions for Safe Use
• Before wiring, make sure that the charge indicator is not lit.
• Once the power supply is turned on, the capacitor in the inverter remains charged with a high
voltage for a while after the power supply is shut off regardless of whether the inverter is run-
ning or not, which is dangerous.
• If you change cable connections after the power supply is shut off, wait for at least
10 minutes and, before wiring, check with a circuit tester etc. to be sure that there is no resid-
ual voltage between terminals P/+2 and N/−.
