•
tighten the nuts on the cable bushings to seal them and protect the cables from unwanted pulling out of the
clamps;
•
insert the base back into the cap and fix with screws.
For the mounting in a humid environment it is
recommended to apply silicone sealant on the outer perimeter of the seating edge of the base before screwing
the box back together;
•
if the internal rules or the mounting process needs the antifraud seal to be installed (as the protection from
the unwanted influencing), stick the antifraud seal across the joint between the two parts of the box.
(*) ATTENTION!
If the module is sealed by additional silicon filling with IP68 degree of protection do not open
its casing during the installation! Meter outputs can be connected to appropriate wires of the input cable (that had
been connected to the module before silicon filling) and configuration could be performed by radio or by using of an
optical converter USB-IRDA.
If the module is rated in IP65 or IP68 degree of protection, this declaration is valid only under condition of the
proper mounting and sealing. When assembling the modules with IP68 degree of protection that will be placed in the
humid environment, it is necessary to follow these rules:
- both cable bushings must be properly sealed;
- the joint of both parts of the box must be properly sealed by original rubber sealing).
After the mounting, write down the counter values of all consumption meters connected to the module into the
mounting sheet and alternatively once again check out the module‘s functionality and the correctness of output
values (which must correspond to consumption meter mechanical counters). Test the module functionality by
”
end-to-end” method, that means by checking of the readings directly in the central system of remote reading.
Follow the consumption meter manufacturer’s instructions for determination of the length of the connection cables
between the consumption meters and the radio modules.
When locating installation site, selecting antenna type and antenna position it is necessary to take into account
conditions for radio signal propagation in the area of installation as well as protection of the device against possible
mechanical damage. The radio-signal conditions can be estimated empirically on the base of previous experience,
or examined by measuring of the signal strength by the reference transmitter/receiver.

Module and meter replacement
When there is necessary to replace the module due to the module failure or due to battery discharging follow this
procedure:
•
check the antifraud seal before dismantling – the antifraud seal damage must be solved according to the
internal rules of the customer/project;
•
unscrew two screws on the sides of the module base (beside the cable bushings), loosen the cap of the module
and slide out the base from the cap;
•
disconnect the cables from the consumption meters from the input clamps, alternatively disconnect the cable
of the external antenna from the antenna connector;
•
by switching of both of the micro-switches (
”
jumpers”) placed on the PCB beside the configuration connector
into the
”
OFF“ position (or replacing of shortening connector from shortening pins) disconnect the module
from the battery power supply;
•
loosen the fixing screws (or clamping tape) that hold the module on the wall, pipe or other pad and dismantle
the cap;
•
put both parts of the module back together by screwing the cap together with base (*). Mark the module
visibly as
”
defective”, alternatively you can fill in the form (mounting report) about the module replacement;
•
install a new module in the same way as described in paragraph
above. Pay attention to the correct
connection of the input cables (must be the same inputs as they were on the original module) and set up the
relevant configuration parameters, namely broadcasting period and input/output values.
•
write down the serial number and seal number of the module, alternatively also actual statuses of counters of
connected meters;
•
if possible, arrange making of all appropriate changes in the database of the remote reading system immedi-
ately.
(*) CAUTION!
The type label with RF-address and serial number of the module is always on the cap of the
module so the base and the cap of the module must always be one whole unchangeable unit. Always pay attention to
the completing of the correct cap with the correct base of the module, that is the reason why it is always necessary
