Module identification
51
The way the identification number is built directly
IOEC module location
corresponds to the wiring diagram as can be seen
in Figure 50. The letter A represents the kind of
part we have, an assembly, the next three digits
are the page number the part is located on, page
154, and the last digit, 1, means that our part is
the first assembly on the page. This identification
label number is the key to track electrical devices
throughout the drive and in ABB documentation.
The designation for each IOEC module is shown in
Table 10.

* No customer connections. Only for internal drive related use.
24 V internal voltage supply
One isolated DC/DC converter supplies an overload
protected voltage of 24 V DC to operate digital
inputs from passive contacts. The output is
protected by a PTC-resistor against short
circuit and external applied overvoltages.

Location
The IOEC modules are installed in the control
compartment of the drive. The standard IOEC
module internal to the drive is DIN rail mounted
on the back side of the swing door. If there is an
optional internal IOEC module, it will be mounted
below the standard one.
The standard customer communication IOEC
module is DIN rail mounted along the right side
wall of the control compartment. If there is an
optional expansion customer communication
IOEC module, it will be DIN rail mounted just
below the standard one.
