Potential safety hazards

The RMC uses voltages in the range of 9-30 Vdc plus some percent of tolerance. There are no
hazardous voltages present in the device. However, some optional power sources might convert
power from Vac to Vdc.
Pressurized natural gas is present in the measurement pipeline. Natural gas can escape from the
pipeline during installation, calibration, or following damage to the pipeline. Only properly trained and
authorized personnel should work in hazardous locations.
The device can be operated at high levels of pressure and with aggressive media. Serious injury
and/or considerable material damage can be caused if this device is handled incorrectly.
WARNING – Bodily injury. Apply power only after the procedures are complete. Technicians
must perform the procedures in order: plan, install, wire, verify the power-on sequence, and
configure.
WARNING – Bodily injury. The device can be operated at high levels of pressure and with
