parts are included in this chapter.
Remove Power from the AFE
1. Turn off and lock out input power.
2. Wa i t f i v e m i nu t e s .
3. Check the DC bus voltage at the power terminal block by measuring
between the +DC and –DC terminals, between the +DC terminal and
the chassis, and between the –DC terminal and the chassis. The voltage
must be zero for all three measurements.

ATTENTION: To avoid an electric shock hazard, verify that the voltage on the bus
capacitors has discharged completely before servicing. Check the DC bus voltage
at the Power Terminal Block by measuring between the +DC and -DC terminals,
between the +DC terminal and the chassis, and between the -DC terminal and
the chassis. The voltage must be zero for all three measurements.
Remove power before making or breaking cable connections. When you remove or
insert a cable connector with power applied, an electrical arc may occur. An
electrical arc can cause personal injury or property damage by:
• sending an erroneous signal to your system’s field devices, causing unintended
machine motion
• causing an explosion in a hazardous environment
Electrical arcing causes excessive wear to contacts on both the module and its
mating connector. Worn contacts may create electrical resistance.
