Chapter 3 - Control system
The designation for each IOEC module is shown in Table 3-2.
Table 3-2 Module identification
3.3.1.4 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.

3.3.1.5 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. See Figure 3-12.
