Available Interface Submodules
Note
Only use interface submodules that are explicitly released for use in S7-400
devices.
Installing Interface Submodules
!
Warning
The modules can be damaged.
When inserting or removing interface submodules with power applied, the CPU
and interface submodules can be damaged (exception: using synchronization
submodules in an H system).
Never insert or remove the interface submodules while power is being supplied
(exception: synchronization submodules). Always switch off the power supply
before inserting or removing interface submodules.
!
Caution
Danger of damage to persons and property.
Interface submodules contain electronically-sensitive components that may be
damaged if they are touched.
The surface temperatures on the components can reach up to 70
o
C and there is
a risk of burning.
For this reason, you should always hold the interface submodules on the longest
sides of the front panel.
Observe the ESD guidelines when installing interface submodules.
To fit an interface submodule in a card slot, follow the steps outlined below:
1. Make all the required settings on the submodule (for example, setting the rack
number on a synchronization submodule).
2. Hold the interface submodule on the long sides of the front plate.
3. Insert the PCB end of the interface submodule in the lower and upper guides of
the card slot, as shown in Figure 6-4.
4. Slowly push the interface submodule into the slot until the front plate rests on
the frame of the card slot.
5. Important! Secure the front plate with the two fitted, captive M2.5 x 10 slot-head
screws on the left frame of the card slot.
