3.2 Electrical connection
The electrical connection must only be carried out by
an authorised electrician in accordance with local
regulations.
3.2.1 Connection of Ethernet
The CIM 500 is designed for flexible network
installation. The built-in two-port switch makes it
possible to daisy chain from product to product
without the need of additional Ethernet switches. The
last product in the chain is only connected to one of
the Ethernet ports. Each Ethernet port has its own
MAC address.

1. Remove cover from E-Box.
Fig. 4 Connection of Ethernet
2. Connect Ethernet cables with RJ45 plugs to
connections (1), (2).
– Depending on the local network installation,
one or two cables can be connected.
3. Connect cable screens to earth via the earth
clamps (7).
4. If necessary, connect earth conductor to
functional earth terminal (8) at earth connection
(3) and tighten clamp (9).
5. Fit housing cover and tighten screws.
– Make sure that the gasket is positioned
correctly.
For further information (e.g. connection to web
server) see installation and operating instructions of
the CIM 500 module.
Warning
Before beginning the electrical connection,
make sure that the power supply of the
DDA dosing pump has been switched off,
and that it cannot be accidentally switched
on.
Warning
To ensure enclosure class IP65 / NEMA
4X, all unused connections have to be
fitted with a blind plug!
Supply voltage of the E-Box: 30 VDC from
DDA pump. See fig. 1, pos. 4.
Connect E-box to power supply only via
the SMART digital S DDA pump using the
pre-assembled plug!
To ensure a stable and reliable
communication, the cable screen for
GENIbus connection must always be
connected to the earth clamp. This is
pre-assembled by Grundfos.
See fig. 1, pos. 4.
Do not make any changes!
