Installing Interface Modules
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
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. Hold the interface submodule on the long sides of the front plate.
2. Insert the PCB end of the interface submodule in the lower and upper guides of
the card slot, as shown in Figure 6-4.
