10.1.3 Connection of Components
The integrator is responsible for the final integrated system. Incorrectly
designed or installed, external components may cause radiation limits to be
exceeded. For instance, improperly made connections or improperly
installed antennas can disturb the network and lead to malfunctions in the
Control Terminal or equipment.
10.1.4 Network and Subscription
• Before your application is used, you must ensure that your chosen
network provides the necessary telecommunication services. Contact
your service provider to obtain the necessary information.
• If you intend to use SMS in the application, ensure this is included in
your (voice) subscription.
• Consider the choice of the supplementary services described in section
“Short Message Service”, page 11.
10.2 How to Install the Control Terminal
10.2.1 Power Supply
• Use a high-quality power supply cable with low resistance. This ensures
that the voltages at the connector pins are within the allowed range,
even during the maximum peak current.
• When the unit is powered from a battery or a high current supply,
connect a fast 1.5A fuse in line with the positive supply. This protects
the power cabling and Control Terminal.
10.2.2 Securing the Control Terminal
• Before securing the Control Terminal take into account the amount of
additional space required for the mating connectors and cables that will
be used in the application.
• Where access is restricted, it may be easier to connect all the cables to
the Control Terminal prior to securing it in the application.
• Securely attach the Control Terminal to the host application using two
3mm diameter pan-head screws of appropriate length as shown below.
Caution! Do not exceed a torque of 25Ncm when tightening the fixings screws.
Excessive torque applied to the screws can crack the plastic case.
