Non Ex
If your model is designed for remote totalizing, you can install the totalizer at a distance of up to
3 m from the meter case. Usually, the cable has already been connected to the sensor and the
totalizing unit when the device is delivered. Should this not be the case, you will have to connect
the connecting cable to input X5, terminals S1+ and S1- of the board. If you have a 2-channel meter
connect the second sensor to the clamps S2+ and S2-. Use only shielded cables of the type:
LIYCY - 2 x 0.75 blue (1-channel Ex)
LIYCY - 2 x 2 x 0.75 blue (2-channel Ex or 1-channel Non-Ex)
LIYCY - 3 x 2 x 0.75 blue (2-channel Non-Ex)
Maximum cable length: 3 m (installation with longer cable only on request)
In hazardous areas the temperature transmitter must not be connected via the
socket on the meter case. In this case it is prescribed to lay a separate cable for the
temperature transmitter!
In addition, check the plug-in jumpers XS1 / XS2 and XTERZ90 on the board (see inputs and
outputs in the annex).
Make your settings of XS1 and XS2 as follows: jumpers 3-4.
