Mounting Dimensions

DIN-Rail Mounting

The aluminum DIN-Rail attachment plate should be fixed to the back
panel of the IMC-21A when you take it out of the box. If you need to
reattach the DIN-Rail attachment plate to the IMC-21A, make sure the
stiff metal spring is situated towards the top.

Wiring Requirements

Safety First!

•

Be sure to disconnect the power cord before installing

and/or wiring your Moxa IMC.

•

Calculate the maximum possible current in each power

wire and common wire. Observe all electrical codes
dictating the maximum current allowable for each wire
size.

• If the current goes above the maximum rating, the wiring

could overheat, causing serious damage to your

equipment.
