3�- INSTALLING THE DEVICE

3.1.- PRELIMINARY RECOMMENDATIONS

In order to use the device safely, it is critical that individuals who handle it follow

the safety measures set out in the standards of the country where it is being used,

use the personal protective equipment necessary (rubber gloves, face protection

andapprovedame-resistantclothing)topreventinjuriesduetoelectricshockor

electric arc due to exposure to current-carrying conductors and pay attention to

the various warnings indicated in this instruction manual.

The LR1RS+mustbeinstalledbyauthorisedandqualiedstaff.

The power supply must be disconnected before handling, altering the connections or replacing

the device. Handling the device while it is connected is hazardous to people nearby.

It is essential to keep the cables in a perfect condition to avoid accidents, personal injury and

damage to installations.

Limittheoperationofthedevicetomeasuringthespeciedcurrentorvoltagevalues.

The manufacturer of the device shall not be held responsible for any damage resulting from the

user or installation company failing to observe the warnings and/or recommendations indicated

in this manual nor for any damage resulting from the use of non-original products or accesso-

ries or those from other brands.

Do not use the device to take measurements if you detect an anomaly or malfunction.

The device must be disconnected from its power supply sources (power supply

and measurement) before undertaking any installation, repair or handling opera-

tions on the device’s connections. Contact the after-sales service if you suspect

that there is an operational fault in the device.

3.2.- INSTALLATION

While the device is connected, the terminals, opening the cover or removing el-

ements may expose hazardous live parts. The device must not be used until the

installation process is complete.

LR1RS+ PSAC has been designed for DIN rail assembly.

LR1RS+ PSDC has been designed for wall assembly with industrial adhesive.

Instruction Manual

4.3.- OPERATING PRINCIPLE

The LR1RS+ is a gateway for converting data between the RS-485 physical environment and

the LoRaTM long-range wireless network.

These devices can be used to connect multiple RS-485 buses to a master, considerably reduc-

ing the cabling required. This can be done by simply connecting an LR1RS+conguredasthe

Master to the RS-485 master, and an LR1RS +conguredastheSlavetoeachofthebusesto

be connected; see Figure 4.

Figure 4: Example of LoRaTM connection�

There can be up to 32 end devices on each communications bus.

Communication between the LR1RS+ master and slave devices is fully transparent, therefore

allowing straightforward installation by simply controlling transmission time between messages

and the time-out period from the application’s master.

4.4.- LoRaTM COMMUNICATION

The device is connected to LoRaTM radio technology for private networks.

LR1RS+ devices can only be used in private networks and cannot be connect-

ed to LoRaWAN networks.

In Europe the frequency for LoRaTM communications is the 868 MHz ISM free band, allowing

congurationofupto9differentchannelsbetween865.1MHz(channel0)and869.85MHz

(channel 9). The default frequency is 869.525 (channel 7).

The device has 10 transmission and reception modes (Table 6) in order to select speeds be-

tween 300 bps and 21875 bps, with the option of increasing communication speed by trading

off transmission signal range.
