15. Auxiliary Equipment Mounting

All RABO meters are equipped with threaded holes for mounting
compact, lightweight auxiliary equipment [Figures 30 and 31].
All holes are M6 x 1 by 10mm deep. Heavier equipment should
be pipe or wall mounted adjacent to the meter. Elster provides
customized brackets for commonly used equipment [Figure 32].
Please contact your local Elster representative for details.
