2.4.2
Install Mounting Base
!
Attention
During panel or DIN rail mounting of all devices, be sure that all debris
(metal chips, wire strands, etc.) is kept from falling into the module.
Debris that falls into the module could cause damage when power is
applied to the module.
To install the mounting base on the DIN rail, proceed as follows:
1.)
Position the mounting base vertically above the installed units (adapter, power
supply or existing module.
2.)
Slide the mounting base down allowing the interlocking side pieces to engage
the adjacent module or adapter.
3.)
Press firmly to seat the mounting base on the DIN rail. The mounting base will
snap into place.
4.)
To remove the mounting base from the DIN rail, remove the module, and use a
small bladed screwdriver to rotate the base locking screw to a vertical position.
This releases the locking mechanism. Then lift straight up to remove.
2.4.3
Install the I/O Module
The module can be installed before, or after base installation. Make sure that the
mounting base is correctly keyed before installing the module into the mounting base. In
addition, make sure the mounting base locking screw is positioned horizontal referenced
to the base.
