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. 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:

• all connectivity work must be carried out with the power turned OFF;
• use appropriate tools and personal protection against electric shock;
• do not use damaged cables, wires and connectors;
• avoid folding the cables and wires;
• 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;
• do not use the power socket with poor contacts to connect;
• do not exceed the load limit parameters specified in the manual;
• 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.

When the power is on, NEVER:

• connect/disconnect the connectors;
• open modules and sensors.

Module installation and connection procedure

1. Install the module in the switchboard on the DIN rail and fix it with the special latch on the module base.
2. Connect the RS485 and MBUS connector.
3. Connect the CAN connector.
4. Configure the module using LT setup.
5. Check all equipment for proper operation.

Module shut-off and deinstallation procedure

1. Disconnect the CAN connector.
2. Disconnect the MBUS and RS485 connector.
3. Remove the module from the DIN rail, releasing the latch at the bottom of the module base.

HW settings

Name	Type, range	SUBID	Default	Description
cfg	string	98	9600/8N1	cfg='SPEED/BPS', where SPEED – baud rate [1200..115200]; B – data length [7,8]; P – presence and type of parity bit [N(No parity),E(Even parity),O(Odd parity)]; S – stop bit length [1, 1.5 or 2]. Example: 1hw="cfg='9600/8N1'"
[Protocol]	string	98	—	Protocol setting is described by protocol parameter. The following protocols are supported: 'modbus', Modbus protocol, at the end of redirection the checksum CRC16(Modbus) is added; 'dmx', DMX protocol; 'CO2' for connecting Larnitech CO2 sensors; 'salda' for connecting Salda ventilation. Example: 1hw="cfg='9600/8N1' modbus"
echo	on; off	98	'off'	For settings check out and testing echo parameter can be used. Module echo-reply can be turned on or off with the help of this parameter.Echo parameter value: 'off' 'on' Example: 1hw="cfg='9600/8N1' echo='off'"
term	integer 0-1	98	'0'	Turning on built in RS485 bus 120Ω terminator Example: 1hw="cfg='9600/8N1' term=1"
mbus	params	2	-	Sets the polled counters on the MBUS mbus='<address1>:<mask1>:<period1> <address2>:<mask2>:<period2>' where: <addressX> - counter address on the bus <maskX> - The bit mask specifies which parameters of this counter will be included in the report and will be sent by the module to the server. Here the lowest bit specifies the presence of general information in the report, and the remaining 31 bits correspond to parameters from "0" to "30". This field can be skipped. By default, it is 0xFFFFFFFFFFFF <period2> - the polling period for this counter in minutes. This field can be skipped. The default value is 15. The range of possible values is from 10 to 1440 Example: 1 <item addr="326:2" cfgid="135" hw="mbus='1:0xFFEC:20'" name="MBUS" type="com-port"/>
