Chapter 2 Drive Electrical Installation
Insulation Resistance (IR)
Test of Power Cables
Before connecting the incoming line and outgoing motor power cables, follow
standard industry practice to verify the integrity of the power cable insulation
from the input breaker to the drive and from the drive to the motor.
Connect Incoming Line and
Outgoing Motor Power
Cables
The installer must ensure that all power connections are in accordance with
national and local electrical codes.
Each drive is equipped with provisions for bottom power cable entry as
standard. Provisions for top power cable entry can also be provided. This must
be specified at the time of order.
For the location of incoming line and outgoing motor power cable
connections, refer to the customer-specific Dimension Drawing.
The drive is supplied with the following provisions for power cable lugs.
Connect Cables for A-Frame Drives
For A-Frame drives, Figure 18, shows typical connection points for the primary
entrance/exit cable.
1. Connect the three-phase medium voltage inputs L1, L2, and L3 for top or
bottom entry to the user-provided input three-phase AC power.
2. Connect three-phase medium voltage inputs U, V, and W for top or
bottom entry to the user-provided three-phase asynchronous motor.
3. Cable clamps are provided in the cabinet to aid in routing and
supporting the incoming line and outgoing motor power cables.
Remove Barrier for Bottom Entry Connections
If you choose to connect the cables through the bottom entry of the A-Frame
drive, you have to remove the insulation barrier before you proceed.
1. Remove the three plastic M6x25 bolts that secure the removable
insulation barrier.
2. Pull out the removable barrier.
3. Connect the cables.

IMPORTANT
If a filter cabinet is supplied, the incoming line cables are from Junction
cabinet and outgoing motor cable connections are in the filter cabinet
(see Figure 19). See the PowerFlex 6000T Drives Hardware Service
Manual, publication 6000-TG100
.
IMPORTANT
Cable entry and exit cable holes should be sealed.
