Optional settings
If your unit is the first or the last unit on the Modbus RTU network (see
Example 1
and
Example 2
), enable the NBT resistor via 3SModbus or Sensistant. If your device
is not an end device, leave the NBT disabled (default Modbus setting).

ATTENTION
If an AC power supply is used with any of the units on a Modbus network, the
GND terminal should NOT BE CONNECTED to other units on the network or
via the CNVT-USB-RS485 converter. This may cause permanent damage to the
communication semiconductors and / or the computer!
ATTENTION
Do not exceed the maximum power supply rating! Measure before installation!
Unregulated 24 VAC supply units provide higher nominal output voltage and
activate the integrated fuse protection.
ATTENTION
We advise you not to use G and F-type articles together on the same network. If
G and F-type articles are used together on the same network, make sure you use
separate power supplies for both types. Always connect different article types to
separate AC transformers or use the same article version.
CAUTION
Do not expose to direct sunlight!
