7 Instructions for the safe Installation and use
The 9522A is intended for integration into a finished product. The
integrator of the 9522A is required to connect a power supply, antenna,
and user interface to the 9522A. To ensure that the 9522A is correctly
installed the following general instructions (sub-section 7.1) are
provided for the installer.
The integrator will be required to supply the end user of the integrated
product, incorporating the 9522A, with operating instructions and any
other information relating to the maintenance and safety of the
equipment (sub-section 7.2).
7.1 Instructions for the Integrator
The 9522A must be installed by an appropriately qualified installer and
mounted securely as described in section 4.4 of this document.
The power supply used to power the 9522A must be checked to ensure
it meets the requirements of sub-section 6.1.2 of this document.
Electrical connections to the 9522A multi-interface connector shall be as
designated in Table 2 of sub-section 4.3.1 of this document.
