Installation
3.3
Electrical Connection
The sensors are connected via M12 x 1, 5-pin connectors with MODBUS RTU. There are
sensor models with one connector (V15) or two connectors (2V15).
One-connector sensors have a male connector.
Connecting the sensor to voltage
Connect the operating voltage to pins 2 and 3 of the 5-pin connector.
3.4
Configuring/Connecting the Terminator
To ensure a secure signal transfer, both ends within a MODBUS RTU segment must be closed
with a 120
Ω
terminator. If the inclination sensor is installed at the beginning or the end of the
MODBUS RTU, a terminator must be used. The inclination sensor is equipped with a built-in
terminator to be activated/deactivated by setting the correct register (See chapter 4.4). It is also
possible to use an external terminator, which can be more suitable in some cases.
The bus wires can be routed in parallel or twisted, with or without shielding, in accordance with
the electromagnetic compatibility requirements. A single-line structure minimizes reflection.

Warning!
Damage to the device
Connecting an alternating current or excessive supply voltage can damage the device or cause
the device to malfunction.
Electrical connections with reversed polarity can damage the device or cause the device to
malfunction.
Connect the sensor to direct current (DC). Ensure that the supply voltage rating is within the
specified sensor range. Ensure that the connecting wires on the cordset in use are connected
correctly.
