You can achieve optimum results with respect to a high-quality and durable electrical
connection with maximum conductor extraction forces through the use of crimp
shapes, preferably with smooth surfaces. Options are, for example, rectangular or
trapezoidal crimp cross-sections.
Due to the large variety of crimp shapes used in the industry, we will be glad to
provide more recommendations upon request. Crimp shapes with pronounced
wave profile are not permitted.
Equipping
•
Check the power module for damage! You may only plug undamaged power
modules onto the BaseUnit.
•
When configuring the ET 200SP HA and the ET 200SP, you must observe the
permissible number of I/O modules (see the respective operating instructions).
WARNING
Permissible number of I/O modules
When configuring the ET 200SP HA and the ET 200SP, you must observe the rules
specified below for the maximum configuration and load of the Ex power modules.
Load on the Ex power modules
•
Ensure that the current consumption of the Ex I/O modules of an Ex module group
does not exceed the permissible output current of the Ex power module.
•
The maximum current requirement of the I/O module can be found in the
technical specifications.
Permissible output current of the Ex power module > ∑ I
