General rules for installation
WARNING
Hazardous Voltage
Can Cause Death, Serious Injury, or Property Damage.
Hazardous electrical voltage can cause electric shock, burns and property damage.
Disconnect your system and devices from the power supply before starting any assembly
tasks.
Observe the following rules:
●
Installation starts on the left-hand side with the CPU/interface module.
●
A light-colored BaseUnit BU..D0, BU30-MS1 or BU30-MS3 with infeed of the supply
voltage L+ follows the CPU/the interface module or is placed at the start of each potential
group.
If you fit an AC I/O module or an AI Energy Meter as the first I/O module, then the first
BaseUnit in the structure of the distributed I/O system ET 200SP may be a dark-colored
BaseUnit. The requirement is that you use a CPU or IM 155-6 (as of V3.0).
●
This is followed by BaseUnits BU..B, BU30-MS2 or BU30-MS4 (with a dark-colored
terminal box).
●
The matching I/O modules / motor starters can be plugged onto the BaseUnits. You will
find matching combinations of BaseUnits and I/O modules / motor starters in Application
●
The server module completes the configuration of the ET 200SP distributed I/O system.
Note
Mount the ET 200SP distributed I/O system only with disconnected supply voltage.
For fail-safe ET 200SP modules:
WARNING
Protection from conductive contamination
Taking into account the environmental conditions, the devices must be protected from
conductive contamination.
This can be achieved, for example, by installing the devices in a control cabinet with the
appropriate degree of protection.
