This manual describes how the GPRS-A module should be installed. For further information
related to the module, including its configuration and operation, please refer to the full version
of manual, available at
www.satel.eu
1. GPRS-A module installation
Disconnect power before making any electrical connections.
It is not advisable to power up the module if the antenna is not connected.
The installation to which the module is to be connected should be provided
with:
2-pole disconnector,
short-circuit protection with a 16 A time delay circuit breaker.
The GPRS-A module should be installed indoors, in spaces with normal air humidity. When
selecting the mounting location, remember that thick masonry walls, metal partitions, etc. will
reduce the range of radio signal. It is not advisable to install the module in close vicinity to
electrical installations, because this can result in malfunctioning of the device.
If the module is to comply with requirements of the EN50131 standard for Grade 2, it
must be installed in an additional enclosure that will enable it to meet requirements of
the tamper standards (e.g. in the SATEL OPU-3 or OPU-4 enclosure).
1.1 Preparing the cabling
Run the cables to be used for connecting the module with other devices to the module
installation place. Do not lay the cables in immediate vicinity of the low-voltage electrical
network wires, especially those used for supplying the high-power equipment (such as
electric motors).
It is recommended that unshielded non-twisted cable to be used.
1.2 Installation of the module
The module enclosure base makes it possible to secure the module to the mounting surface
by using e.g. a cable tie or angle hooks.
