Safety precautions
Warning!
Mechanical and electrical installation of the WM868-MS-LP-H module can be provided only by a person
with necessary qualification in electrical engineering.
4.5
Environmental protection and recycling
The equipment does not contain exchangeable components, which require compliance with specific rules in terms
of environmental protection for their replacing, storage and disposal. Damaged, destroyed or discarded devices
cannot be disposed as household waste. Equipment must be disposed of in the waste collection yards, which dispose
electronic waste. Information about the nearest collection yard can be provided by the relevant local (municipal)
authority.

WM868-MS-LP-H module installation
The WM868-MS-LP-H radio modules are enclosed in plastic casings with an IP20 degree of protection equipped by
plastic locks for mounting on the DIN-rail. Casings should not be open under mounting, dismantling and normal
operation.
Detailed view of the WM868-MS-LP-H module from the power supply clamps side and from the rear side is shown
in figure

Installation of the module should be performed by the following procedure:
•
installation of the module can be performed only by a person with necessary qualification in electrical engi-
neering and at the same time trained for this device installation;
•
when selecting an installation site pay attention to secure sufficient space for connection of antenna, power
and signaling cables to the module (see paragraph
”
Risk of mechanical damage”). It is necessary to keep
the sufficient space for the connecting of configuration cable as well;
•
when selecting a site for the module installation it is necessary to choose a place with availability of power
supply. The power supply should be placed close to the module so that the feed of 24 voltage is as short
as possible. Further it is necessary to consider the method of the module switching off and location of an
appropriate disconnecting element (see paragraph
”
Risk of electrical damage”).
•
mount the module to the selected place on the DIN-rail. Pull down black plastic lock in the bottom side of
the module (outward of the module), attach the module to the DIN-rail so that the rail fits into the slot on
the rear side of the module and push the black plastic lock up (inward the module);
•
connect the antenna and signal cables to the module;
•
make sure that the power supply is turned off and connect the power cable to the module. Verify that the
polarity of power supply corresponds with the marking on the module terminals;
•
check whether everything is properly connected and fasted and turn on the power supply. Green LED

will shine on the module and the operation system will start up;
•
perform the basic diagnostic of the module in compliance with the procedure mentioned in the paragraph
”
Functional check of the module” and possibly (if the module was not pre-configured during the prepara-
tory stage of installation) its configuration with using of the configuration cable according to the procedure
described in the paragraph
”
Configuration of the module individual parameters”;
