INSTALLATION
With the Excel 50, two different types of input/output ter-
minals can be used: Screw terminal blocks for direct wiring
and Phoenix terminal blocks for remote wiring within the
same cabinet.
The installation procedures for the two types are different.
For proper installation, follow these instructions:
1.
Read the complete chapter "Installation" carefully.
2.
Depending on which terminal block type you have
chosen:
— Follow the instructions from the chapter "Screw
Terminal Block Installation Procedure".
or
— Follow the instructions from the chapter "Phoenix
Terminal Block Installation Procedure".
Fig. 16. Wiring options.
The two screw terminal blocks are attached directly to the
controller housing.
The Phoenix terminal blocks are connected to the controller
via flat strip cables. The use of Phoenix terminal blocks to-
gether with the flat strip cables will reduce the installation
effort as well as wiring mistakes.
