Step 1: Removing Power
From the Drive
1. Turn off and lock out input power. Wait five minutes.
2. Verify that there is no voltage at the drive’s input power terminals.
3. Measure 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 before servicing
the drive. 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.

Step 2: Removing the Old
Power Structure
Before you can remove the old power structure from the drive, you must
remove the protective screens, protective covers and air flow plate from the
drive.
Removing the Protective Screens and Covers
1. For NEMA/UL Type 1 enclosures, remove the screws that secure the
protective screens to the enclosure and remove the screens.
2. Remove the four M5 POZIDRIV screws that secure each of the three
protective covers to the power structure and remove the protective
covers.

the drive.
4. Slide the airflow plate off of the drive.

Important:Before removing connections and wires, mark the connections
and wires to avoid incorrect wiring during assembly.
5. Remove the motor wiring from the output power terminals on the power
structure.
6. Remove the ground connection from the lower right corner of the power
structure.
7. Remove the input connections from the incoming DC bus terminals at
the top of the power structure.

8. Remove the four screws that secure the cover to the ASIC assembly and
remove the -DC bus connection from the cover.
9. Unplug the cooling fan that mounts to the ASIC assembly cover from
connector X1 on the ASIC board and remove the ASIC assembly cover.

10. Disconnect the fiber optic cables (H1 - H7) from the ASIC board.
11. For drives with 700H control, disconnect the +24V supply cable from
connector X10 on ASIC board #1.
12. For drives with DC input, disconnect the external precharge circuitry
from connectors X9 and X15 from the ASIC board.

13. Pull the rubber grommet, through which the ASIC board and Power
Supply Voltage Feedback board wire bundles are routed, out of the
drive frame and secure the wire bundles in the left-hand enclosure of the
drive.
14. For drives with AC input, disconnect the precharge cable from the
Rectifying modules and the fan control cables, located in the power
structure to the left of the ASIC board.

15. For drives with 700H control, continue with step 19 on page 11. For
drives with 700S control, disconnect the DC bus connection cable from
the connector J2 and the motor feedback connection cable from
connector J1 at the top of each the Power Supply Voltage Feedback
boards (see illustration below for location).
16. Carefully disconnect the fiber-optic cables from sockets J4 and J5 on
the side of each of the Power Supply Voltage Feedback boards and
carefully set them aside (see illustration below for location).
Important:Minimum inside bend radius for fiber-optic cable is 25.4 mm (1
in.). Any bends with a shorter inside radius can permanently
damage the fiber-optic cable. Signal attenuation increases with
decreased inside bend radii.
!ATTENTION: Hazard of permanent eye damage exists when
using optical transmission equipment. This product emits intense
light and invisible radiation. Do not look into fiber-optic ports or
fiber-optic cable connectors.

Feedback board assemblies to the fan housing on the power structures
and carefully remove the Power Supply Voltage Feedback board
assemblies.
