The wireless M-Bus module must be connected to an internal or external antenna. When
mounting an external antenna, ensure that the antenna cable is not jammed or damaged
when the calculator is assembled. Before replacing or mounting modules, the supply to the
meter must be switched off. The same applies to mounting of an antenna.
