Transmitter Housing Grounding

In case you need to ground the transmitter housing, the grounding

connector is found inside the housing (see Figure 1 on page 21) Note

anyhow that the probe is connected to the same potential as the housing.

Make sure that different groundings are made to the same potential.

Otherwise harmful ground currents may be generated.

If it is needed to have galvanic isolation of the power supply line from

the output signals, DMT340 can be ordered with optional output isolation

module.This module prevents harmful grounding loops.

Signal and Power Supply Wiring

When connecting transmitter with 8-pin connector, see section 8-pin

Connector on page 69.
