Function
The power supply unit serves to power gas sensors of the
OPP-SOR® GMF-MOD-IR series whenever more than 7 of these
devices are to be operated within one system. See data sheet
30109. Seven additional sensors of the GMF-MOD-IR series can
be powered with every NTG03 that is added.

Installation and electrical connection
All work (such as installation, electrical connection, startup, ope-
ration, and maintenance) must only be performed by suciently
qualied tradesmen. The respectively applicable local rules and
regulations (e.g. national building codes, electrical/VDE regula-
tions, etc.) must be observed. Installers and operating entities
are required to suciently familiarize themselves before startup.
Read the product description before operating the equipment.
Verify that the product can be used for the relevant application
without restrictions. We are not liable for printing errors and
changes after printing. Appropriate use implies compliance with
operating and installation instructions. We are not liable for losses
due to inappropriate use. Unauthorized or inappropriate mani-
pulations or modications of the device render the operating
permit, the product warranty and warranty claims null and void.

In this example a 4-core cable type is used. The cables are
connected to the terminal strip of the NTG03-24VDC-36W
according to the connections table.
Caution: Do not connect the 24 VDC supply cable of the input
line (IN) to the 24 VDC supply cable of the output line (OUT).
The above application example shows just one of many possi-
bilities. It implies no claim to completeness, nor can it take the
place of proper professional planning with due consideration to
local conditions and regulations.
The LED of the power supply unit serves as an indicator of output
voltage.The green LED indicates an output voltage of ca. 24 VDC
between terminals 2 (24 VDC) and 3 (0 VDC). If the green LED is o
during operation, this indicates a fault condition, e.g. as a result of
overload.
