Note! Resistive current measurement may not always be possible with
this special application.
The assembly of the components is generally as per section 3.4 alter-
native 1, except that the arrester is intended specifically for inverted
mounting. Furthermore, it may be necessary to mount the EXCOUNT-II
sensor "upside down" in certain cases, as shown in Figure 3.7.1. With
such arrangements, special precautions may be necessary to additionally
seal the battery compartment against water ingress.
