PowerFlex Active Front End in IP20 2500 MCC Style Enclosure Frame 10 Bus Splice Kit
ATT EN TI ON : To avoid an electric shock hazard, verify that the voltage on the
bus capacitors has discharged completely before performing any work on the
Active Front End. After power is removed from the Active Front End, wait 5
minutes for the bus capacitors to discharge. Check the DC bus voltage between
the DC+ and DC- terminals, between the DC+ terminal and the chassis, and
between the DC- terminal and the chassis. The measured voltage must be zero
for all three measurements.
ATT EN TI ON : To guard against personal injury and or equipment damage
caused by an ARC Flash, the user must identify the ARC Flash requirements per
NFPA 70E.
ATT EN TI ON : If you do not follow ESD control procedures, the PowerFlex Active
Front End, which contains electrostatic discharge (ESD) sensitive parts and
assemblies, can be damaged. Static control precautions are required when
installing, testing, servicing, or repairing the Active Front End. If you are
unfamiliar with static control procedures, see Guarding Against Electrostatic
Damage, publication 8000-4.5.2, or any other applicable ESD protection
handbook.
Where the Kit Is Used
What the Kit Contains
ATT EN TI ON : An incorrectly applied or installed Active Front End can result in
component damage or a reduction in product life. Wiring or application errors
such as undersizing the motor, incorrect or inadequate AC supply, or excessive
ambient temperatures can result in malfunction of the system.
ATT EN TI ON : The user is responsible for conforming with all applicable local,
national, and international codes. Failure to observe this precaution can result
in damage to, or destruction of, the equipment.
ATT EN TI ON : Only qualified personnel familiar with the construction and
operation of this equipment and the hazards that are involved must plan or
implement system installation, startup, and subsequent maintenance. Failure
to comply can result in personal injury and/or equipment damage.
This kit can be used with only an Active Front End Frame 10 in an IP20 2500
MCC Style enclosure to connect bus bars to an adjacent (right or left side) IP20
2500 MCC Style enclosure with the same bus bar alignment. This provides an inline common bus system configuration.

Right-side Connection
To connect the bus bars and attach an enclosure to the right side of the AFE
enclosure, follow these steps.
Step 1: Remove power from the AFE.
ATT EN TI ON : To avoid an electric shock hazard, verify that the voltage on the
bus capacitors has discharged completely before servicing. Check the DC bus
voltage 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.
a. Turn off and lock out input power.
b. Wait five minutes for bus capacitors to discharge.
c. Verify that there is no voltage at the AFE input power terminals.
d. Check the DC bus voltage 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 before
proceeding.
Step 2: Remove left side covers from the enclosure being connected to the AFE.
Step 3: Remove the AFE enclosure right side covers to access the bus bars.
