Connecting expansion devices/network modules
Local expansion
X Connect the devices to the expansion or to the network module
via the EASY-LINK-DS connection plug.
Remote expansion
Remote expansion units can be installed and run up to 30 m away
from the basic unit.

The following electrical separation is implemented
between the power supply/CPU module of the MFD
device and the expansion unit (separation always in local
connection of expansion unit).
• Basic isolation 400 V AC (+10 %)
• Safe isolation 240 V AC (+10 %)
Units may be destroyed if the value 400 V AC +10 % is
exceeded, and may cause the malfunction of the entire
system or machine!
h
Basic unit and expansion unit can be provided with
different DC power supplies.

Warning!
The two-wire or multiple-wire cable between the devices
must adhere to the insulation voltage requirement which
is stipulated for the installation environment. Otherwise,
a fault (ground fault, short-circuit) may lead to the
destruction of the units or injury to persons.
A cable such as NYM-0 with a rated operational voltage
of Ue = 300/500 V AC is normally sufficient.
h
Terminals E+ and E– of the EASY200-EASY are protected
against short-circuits and polarity reversal. Functionality
is only ensured if E+ is connected with E+ and E– with E–.
