Installing the Switch on a DIN Rail
The switch ships with a spring-loaded latch on the rear panel for a mounting on a DIN rail.
You can install the switch as a standalone device on the DIN rail or with the expansion modules already connected. You
must connect expansion modules to the switch before installing the switch on the DIN rail.
To attach the switch to a DIN rail, follow these steps:
1.
Position the rear panel of the switch directly in front of the DIN rail, making sure that the DIN rail fits in the space
between the two hooks near the top of the switch and the spring-loaded latch near the bottom.
2.
Holding the bottom of the switch away from the DIN rail, place the two hooks on the back of the switch over the top
of the DIN rail.
Caution:
Do not stack any equipment on the switch.
