To ensure safety, the recorder's supply must satisfy the conditions
applicable to lower voltage sources SELV (Safety Extra Low-
Voltage), supplied with the 24 VDC as per the IEC60950-1.
In order to eliminate interference, it is recommended to connect the ground wire to the
terminal block (terminal no. 15). It is so called functional ground. This connection is not
required due to safety requirements.
Power consumption depends on the quantity and type of input and output modules. It
should be taken into account that the maximum permissible ambient temperature depends
on device configuration, details are described in section

Notes:
If screened cable is used to connect transducer, then GND A terminal may be used to
connect the screen. But it is more recommended to connect screen to functional ground or
metal cabinet ground (PE).
