Frame 11 Fan System
Replacement Procedures

Replacement procedures for these frame 11 fan system parts are included in this
chapter.

Remove Power from the Drive

1.

Turn off and lock out input power.

2.

Wait five minutes.

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.

Cat. No.

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.
