DIN Rail and Panel Mounting
Each rack in a VersaMax PLC or VersaMax I/O Station must be installed on a
single section of 7.5 mm x 35 mm DIN rail, 1 mm 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 5.24 cm (6 in) apart. DIN-rail clamps (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 provided in
Appendix A
. Pre-drill the
mounting holes and install the CPU, NIU, ERM, and carriers using M3.5 (#6)
screws.
