There are two mounting methods for the NXS:
DIN Rail Mounting
DIN rail mounting is the preferred method. The following procedure provides step-by-step instructions for mounting
the NXS on DIN rail.
Procedure 1 To mount on DIN rail.
Step 1 Position the NXS on the DIN rail, tilting to hook clamps over the top edge of the rail
Step 2 Swing the device down fully onto the DIN rail, until both clamps completely latch.
Step 3 Mount other modules (Power Supply, NXS-UPS, Battery) onto DIN rail in the same fashion—see the
installation document shipped with each module for complete details.
Step 4 If needed, secure devices with DIN rail
