8.2 How to install the modem
8.2.1 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 1.25A fuse in line
with the positive supply. This protects the power cabling and modem.
8.2.2 Securing the modem
Before securing the modem 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 modem prior to
securing it in the application.
•
Securely attach the GT864-QUAD/PY Terminal modem to the host application using two 3mm
diameter pan-head screws
