Installing the Mounting Base
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.
Installing 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.
1. Using a bladed screwdriver, rotate the keyswitch (2) on the
mounting base clockwise until the number required for the
type of module being installed aligns with the notch in the
base.
2. Make certain the DIN rail locking screw is in the horizontal
position. (You cannot insert the module if the locking
mechanism is unlocked.)
WARNING
!
When you insert or remove the module while
backplane power is on, an electrical arc can
occur. This could cause an explosion in
hazardous location installations. Be sure that
power is removed or the area is nonhazardous
before proceeding.
