Chapter 8 Installation
The following step is only necessary if you are using an external supply or charging voltage.
11. Now switch on the external supply or charging voltage.
Note: If you are using a power supply unit without an integrated energy store, the external supply or
charging voltage must be switched on before the optional step during which the connection to the server
is tested.
8.6.1.1 Connection examples
Connection examples
1 Main terminal block of the NivuLog Easy V3 4 2-wire mA sensor
2 Isolated relay contact 5 3-wire mA sensor or 3-wire U-sensor
3 Sensor with open collector output
Note: The "Cnt.Day" and "Cnt.Intervl." operating modes require a permanent supply of the sensors.
One of the two switchable sensor supplies must be permanently active for this purpose. The use of
VEXT is recommended for this purpose (see sensor 1 in the connection example above). The power
consumption per input when the switch contact is closed can be up to 384µA due to the load of 8k6 .
8.6.2 Connecting the GSM antenna
Important note: To ensure the correct functionality, only use antennas that are supplied by the
manufacturer.
The standard antenna (Portable antenna multi band , NLM0ANTFMEMULT ) is directly attached to the
antenna connector (see "Overview" on page 22) of the NivuLog Easy V3 . In the event of a low radio signal
strength, you can use the Circular antenna for mounting on switch cabinets etc. (NLM0EMATR02 ).
If the distance between the antenna position and the NivuLog Easy V3 is too great, you can use a 5 m
Extension for antenna 900 FME, 5m (NLM0ANTVER05).
1. Ensure that the NivuLog Easy V3 is de-energised.
2. If you need an antenna extension, connect it to the antenna first.
