AFE in IP21 Rittal Enclosure – Installation/Wiring Chapter 2
• When it is unavoidable to cross control and signal wires with power
wires, always cross power wires at a 90° angle.

Figure 39 - AFE I/O Terminal Blocks and Jumpers
IMPORTANT I/O terminals that are labeled ‘(–)’ or ‘Common’ are not referenced to earth
ground. They are designed to reduce common mode interference.
Grounding these terminals can cause signal noise.
ATTENTION: Inputs must be configured with software and jumpers (see
Analog I/O Configuration on page 79 ). If you configure an analog input for
0…20 mA operation and drive it from a voltage source, you can cause
component damage. Verify proper configuration before you apply input
signals.
ATTENTION: It is important to disable the variable frequency drives that are
connected to the AFE output when the AFE is not active (not modulating).
Connect the 'Inverter Enable' output of the AFE to each variable frequency drive
enable input, or enable parameter 132 [Contact Off Cnfg] to force off the main
contactor if there is a fault. This action makes sure that once the AFE stops
modulating, there is no motoring current flowing through the AFE IGBT diodes.
Failure to disable the AFE output can result in component damage or a reduction
in product life.
When you enable parameter 132, see page 109 for details. The AFE is shipped
with parameter 132 disabled. The disabled parameter does not stop or shut
down DC output when a fault occurs.
