==RS232 INTERFACE ADAPTER==<br />
<br />
This module is designed for interface adjustment between the devices which have the RS232 interface and the Smart Home system.<br />
<br />
<div class="caution"><br />
CAUTION! All work related to the installation, connection, setting up, service and support must be carried out by qualified personnel with sufficient skills and experience in working with electrical equipment.<br />
To avoid the risk of fire, electric shock, damage to the system and/or personal injury, the system installation and assembly must be performed in accordance with the instructions listed below:<br />
*all connectivity work must be carried out with the power turned OFF;<br />
*use appropriate tools and personal protection against electric shock;<br />
*do not use damaged cables, wires and connectors;<br />
*avoid folding the cables and wires;<br />
*do not apply excessive force to the wires by kinking or pressing them too hard: the inner conductors of the cables and wires may get stripped or damaged;<br />
*do not use the power socket with poor contacts to connect;<br />
*do not exceed the load limit parameters specified in the manual;<br />
*the supply conductors wire section is subject to the specifications for current density limit, insulation type and wire material. Light section can result in cable overheating and fire.<br />
When the power is on, NEVER:<br />
*connect/disconnect the connectors;<br />
*open modules and sensors.<br />

<br />
==Module installation and connection procedure==<br />
#Install the module in the switchboard on the DIN rail and fix it with the special latch on the module base.<br />
#Connect the X1 connector.<br />
#Connect the CAN connector.<br />
#Configure the module using LT setup.<br />
#Check all equipment for proper operation.<br />
<br />
==Module shut-off and deinstallation procedure==<br />
#Disconnect the CAN connector.<br />
#Disconnect the X1 connector.<br />
#Remove the module from the DIN rail, releasing the latch at the bottom of the module base.<br />
