5 Instructions for the safe Installation and use of
the 9522A LBT
The 9522A LBT is intended for integration into a finished product.
The integrator of the 9522A LBT is required to connect a power sup-
ply, antenna, and user interface to the 9522A LBT. To ensure that the
9522A LBT is correctly installed the following general instructions
(sub-section 5.1) are provided for the installer.
The integrator will be required to supply the end user of the integrat-
ed product, incorporating the 9522A LBT, with operating instructions
and any other information relating to the maintenance and safety of
the equipment (sub-section 5.2).
5.1 Instructions for the Integrator
The 9522A LBT must be installed by an appropiately qualified
installer and mounted securely as described in section 3.4 of this
document.
The power supply used to power the 9522A LBT must be checked to
ensure it meets the requirements of sub-section 4.1.2 of this docu-
ment.
Electrical connections to the 9522A LBT multi-interface connector
shall be as designated in Table 3 of sub-section 3.3.1 of this docu-
ment.
