1.2. Safety
Please observe the following instructions:
•
Do not open the unit, except if so instructed by the Metrilog technical personnel!
•
Should it be necessary to open the unit (e.g., to replace the SIM card), the operation must be
executed only in a moisture free environment. You will need a Philips screwdriver size PH2. Note
that the screws remain attached to the lid, there is no need to remove them. Remove the lid slowly
and carefully, because an antenna is fixed on its back. The antenna cable goes to a connector on the
electronics board and it can be easily damaged. Before mounting the lid back, make sure the gasket
is properly seated! If the gasket is damaged, contact Metrilog for a replacement. A defective gasket
will lead to moisture entering the housing, thus permanently damage the unit.
•
Please make sure that all the cables and connectors are properly fasten to avoid moisture entering
the unit and/or the connectors.
•
During normal use outdoors, the dust cover attached to the unit must always be inserted into the
USB connector (see picture above).
•
If either the MPI or the SDI connector is not used, it must be covered with the attached protection
cap.
•
The unit can be powered on all three connectors, even simultaneously, in which case the power
source with the highest voltage will take precedence.
•
The minimum voltage is 6 Volt for the SDI and MPI connectors and 4.7 Volt for the USB connector;
the maximum voltage is 30 Volt for the SDI and MPI connectors and 5.3 Volt for the USB connector.
Under no circumstances should the maximum voltage be exceeded!
•
Improper commands issued through the USB port or over telnet, in particular commands modifying
certain attributes, may compromise the functionality of the RTU and may render it inoperable.
