4-3-1 Installation in a Control Panel
An NJ-series Controller must be mounted inside a control panel on DIN Track. Normally the CPU Rack
is installed on top and the Expansion Racks under it.
• Consider the width of wiring ducts, wiring, ventilation, and Unit replacement when determining the
space between Racks.
• When you install Racks vertically, allow at least 66 mm between any two adjacent Racks.
A Controller must be mounted on DIN Track. It cannot be mounted with screws.
