DIN Rail and Panel Mounting

Each rack in a VersaMax PLC or VersaMax I/O Station must be installed on a single
section of 7.5mm X 35mm DIN rail, 1mm thick. Steel DIN rail is recommended. "Rack" is
the term used for a CPU, NIU, or Expansion Receiver, plus up to 8 physically-connected
I/O carriers. The first rack in a system is called Rack 0. If there are multiple expansion
racks, Rack 0 also includes an Expansion Transmitter module installed in the leftmost
position, before the CPU or NIU.
The DIN rail used in a VersaMax installation must be electrically grounded to provide
EMC protection. The rail must have a conductive (unpainted) corrosion-resistant finish.
DIN rails compliant with DIN EN50022 are preferred.
For vibration resistance, the DIN rail should be installed on a panel using screws spaced
approximately 5.24cm (6 inches) apart. DIN-rail clamps (available as part number
IC200ACC313) can also be installed at both ends of the station to lock the modules in
position.
For applications requiring maximum resistance to mechanical vibration and shock, the
DIN-rail-mounted carriers should also be mounted on the panel. Panel mount holes can be
located on the panel by using the carrier as a template, or by following the dimensions
shown in appendix A. Pre-drill the mounting holes and install the CPU, NIU, ERM , and
carriers using M3.5 (#6) screws.
