Installation and wiring
3.6 General rules and regulations for operating the EIP-200S Ethernet/IP Adapter
Line voltage
The following table tells you what you should do with regard to the line voltage:
With:
Permanently installed plants or systems without
all-pole line disconnect switches
Load power supplies, power supply modules
All circuits of the ET 200S distributed I/O system
24 VDC supply
The following table tells you what you should do with regard to the 24 VDC supply:
With:
Buildings
24 VDC supply lines, signal
lines
24 VDC supply
Protection against outside electrical influences
The following table tells you what to do to provide protection against electrical influences or
faults:
With:

integrated
Supply, signal, and bus lines
Signal and bus lines

Requirements:
There must be a line disconnect switch or a fuse
in the building installation system.
The set rated voltage range must correspond to
the local line voltage.
Any fluctuation/deviation in the line voltage from
the rated value must be within the permitted tol-
erances.
Pay attention to:
Outdoor lightning protection
Indoor lightning protection
Safe (electrical) isolation of extra-low voltage
You must ensure that:
The plant or system is connected to a protective
conductor for diverting electromagnetic interfer-
ence.
The wiring arrangement and installation are cor-
rect.
Any break of a line or conductor does not result in
undefined states of the plant or system.
