2.0 INSTALLATION
2.1 UNPACKING AND INSPECTION
Verify that there has been no damage to the shipping container. If damage exists then the
container should be retained, as it will provide evidence of carrier caused problems. Such
problems should be reported to the carrier immediately as well as to C&H. If there is no damage
to the shipping container, carefully remove the instrument from its box and inspect for any signs
of physical damage. If damage exists, report immediately to C&H.
2.2 HANDLING PRECAUTIONS
The components used in the EM405D are static sensitive. Damage may occur if proper static
precautions are not taken. Installation of M-modules should only be done at a properly grounded
static free workstation.
CAUTION: Read the entire User's Manual before proceeding with the
installation and application of power.
2.3 INSTALLATION OF M-MODULES
To install modules, first remove power from the carrier. Remove the front panel cover by
removing the two screws located at the sides of the panel. Do not remove the screws located on
the bottom of the enclosure. Slide the PCB out of enclosure. Install M-modules by firmly
pressing the connector on the M-module together with the connector on the carrier as shown in
Figure 2. Secure the module through the holes in the PCB using screws provided with the M-
module.
WARNING: The EM405D supports M-modules that use two or three row
interface connectors. When using M-modules with only two
rows, row C of connector (rear row) is left unconnected.
