4. Unscrew and remove the four screws from the corners of the
front panel of the extension slot.
5. Keep the screws in a safe place. They are needed to secure the
ES921.1 module.
6. Remove the front panel.
Four threads for the screws which will secure the ES921.1
module become visible under the front panel.
7. Keep the front panel in a safe place. You need it if you want to
operate the ES910 without the ES921.1.
6.1.2 Installing the ES921.1 in the ES910 Module
There are guide rails on the right and left in the extension slot of the ES910 for
accommodating the ES921.1. The mechanical connection of the modules
simultaneously establishes all necessary electrical connections between the
modules.
To install the ES921.1 into the ES910 module:
1. Place the ES910 on a solid surface.
2. Position the ES921.1 in front of the extension slot of the ES910
module.
Align the back of the ES921.1 with the front of the housing of
the ES910.
3. Slide the module into the guide rails without getting it off-line.
CAUTION
Some components may be damaged or even destroyed by static discharge!
Leave the module in its transport package until you want to install it.
The module should only be taken from its package and installed at a working
place that is protected against static discharge.
CAUTION
Damage to the ES910 possible!
The ES910 module must not be stood on its back when the ES921.1 is
installed in the ES910 module.
NOTE
The labeling on the fronts of both modules must be pointing in
the same direction!
