Chapter 5 Preventative Maintenance and Component Replacement
Using the Lift Cart
Power Modules that are rated above 350 A are shipped separately, therefore site
installation and cable connection is needed. In this case, a lift cart is supplied
for power cell replacement.
The lift cart’s hydraulic cylinder can be operated by either a hand or foot crank.
The lifting capacity is 400 kg (882 lb).
Figure 46 - Lift Cart Procedure
Install Power Module for H-Frame and B-Frame Drives
1. You can use the lift cart to move and position the Power Module to the
appropriate location in the cabinet.
2. Push the Power Module slowly along the guide rails until it cannot be
pushed in further.
ATTENTION:
Only authorized personnel should operate the lift cart. Keep
hands and feet away from the lifting mechanism. Do not stand under the lift
tray when in use. Store the lift cart with the tray fully lowered.

Pressure Release Knob
1. Check the lift tray before use to verify that
the tray can be raised and lowered
smoothly.
2. Rotate the Pressure Release Knob
counterclockwise to verify that the tray is
in the lowest position.
3. Move the Power Module on the tray and lift
the module to the appropriate height using
the Foot Crank and complete the
installation.
4. Rotate the Pressure Release Knob
counterclockwise to lower the tray to its
original position.
5. Repeat steps 1...4 to complete the
installation for all the Power Modules.
The Foot Crank raises the lift tray faster
than the Hand Crank. Use this to raise
the Power Module to just below the tray
assembly in the drive. Use the Hand
Crank for final precise positioning.

IMPORTANT
The Power Module should be handled carefully. After removing the
packaging, inspect the Power Module to confirm that there is no
damage and moisture.
