3.2 Electrical connection
The electrical connection must only be carried out by
an authorised electrician in accordance with local
regulations.
Warning
Before beginning the electrical connection,
make sure that the power supply of the

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.
Caution
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

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.
