Installing the Reader hardware
Prerequisites: The Reader cabinet is commissioned and the earth ground system has been installed
as per IEEE 142-2007 (see The earth ground system on page 144).
Install the AC receptacle for the Reader mains power connections within three (3) feet of the front of
the Reader.
Note: When handling Reader modules and hardware, always follow accepted Electrostatic Discharge
(ESD) practices and standards.
1. Using clip nuts, mount the Reader in the EIA 19-inch rack in a NEMA 4 cabinet.
2. Connect the EIA 19-inch rack ground lug to earth ground:
3. Connect one end of a braided ground strap to the ground lug on the EIA 19-inch rack.
4. Neatly position the ground strap along the Reader and apply a light film of tuner lube to the ground lug on
the rear of the Reader rack to ensure good grounding contact.
5. Secure the other end of the braided ground strap to the Reader ground lug.
CAUTION:
To avoid damaging the modules, ensure that alignment of both
the connector on the module and the connector on the DSM
(back plane) is correct before securely plugging the module into
the DSM.
6. Install the Reader modules in the Reader, ensuring the modules seat properly in their sockets. The
installation of the MRFM-S is outlined in Installing a Lane Kit on page 149.
7. Install the power cords for the primary and secondary PSMs. Appropriate lightning/surge protection
equipment should be installed between the power mains input and the earth ground system at the Reader
(see Figure 5-2 on page 147).
