WARNING
Electric shock
Death or serious personal injury
‐
Connect CIM 550 only to a Grundfos
host product with a dedicated CIM
interface.
‐
Installation must be carried out by
qualified and trained experts.
CAUTION
Radiation
Minor or moderate personal injury
‐
Locate the product at a minimum
distance of 20 cm (0.66 feet) from any
body parts. Human tissue may be
heated by RF energy.
The enclosed label specific to your country must be
attached near the nameplate on the product in which
the CIM module is installed. The label must be visible
and easily accessible.
Check the Compliance Information sheet for your
country specific label.
4.1 Security
The CIM module provides a secure way of performing
data transmission to the cloud. It uses encryption and
mutual authentication based on X.509 certificates for
access authentication. The connected Grundfos host
products must be behind a firewall or connected to a
private network. If a firewall or private network is not
in place, the Grundfos host product may be subject to
a cybersecurity risk and becomes vulnerable to an
attack or compromise.
The CIM module acts as fieldbus master for the
GENIbus and Modbus RTU protocols. These
protocols use the underlying RS485 protocol
communication. As this protocol does not have any
built-in security, it is highly recommended to allow
only authorized persons physical access to the
installation and otherwise adhere to the initiatives
suggested in the local risk assessment if one has
been prepared.
4.1.1 CIM 550
For CIM 550 Ethernet GiC the firewall must accept
connections initialised by the Grundfos host product
to the internet only (outgoing connections).
