10. Wrap electrical tape tightly over the seam (between the cover
and the case) of the GSM module enclosure to enhance the seal
and to simplify the removal of debris when the module is
opened.
Installing the GSM Module
Note: IETG recommends installing the antenna prior to
securing the GSM module to the monitor.
Note: The following instructions address a standard
installation that involves mounting the GSM module inside
the manhole. However, IETG offers an optional extension
cable (p/n 8000-0044-25) that runs between the monitor
and module for mounting the module and antenna outside
the manhole. When installing the module outside the
manhole, provide adequate protection for the module
against environmental elements and vandalism, such as a
weatherproof and secure enclosure. In addition, wrap the
entire connections of the extension cable and module and
the extension cable and monitor port with rubber stretch
tape, extending onto the cables approximately 50 mm (2
in) beyond the connection on each side.
Install the GSM module in the following way:
1. Place the monitor upright on the ground surface beside the
manhole in which the antenna cable is temporarily coiled.
2. Attach the communication cable connector from the GSM
module to the corresponding COMM port on the monitor.
3. Wrap rubber stretch tape around the entire cable connection
(particularly over the gap between the connector and port),
extending up the cable 25 to 50 mm (1 to 2 in) beyond the
connection.
