6.1 Installation
WARNING
Electric shock
Death or serious personal injury
‐ Before installation, make sure that the power supply
has been switched off and that it cannot be
accidentally switched on.
6.1.1 Fitting a cellular antenna
Connect an antenna to CIM 260 to establish connection to the
cellular network.
If CIU 260 is installed in a metal control cabinet, we
recommend fitting an external antenna.
Grundfos offers different kinds of antennas. No antenna is
supplied with CIU 260. You can order it separately.
External antenna
Connect the antenna cable to the SMA connection (pos. 1) of CIM
260. The antenna must be installed outside the control cabinet in a
position with good reception conditions. If required by the telecom
company, connect an additional antenna.
