ABB ADVAC Installation & Maintenance Instructions

18
ABB IB 6.2.15.7-1C
TRUCK: (Refer to Fig. 5)
The truck requires visual inspection of hardware, lubrication and operations during routine maintenance.
With the breaker outside the cell, verify all visible hardware tightness, including handles (1) and wheels (2).
Wheels should rotate freely by hand movement. Replace or tighten any missing or loose hardware.
With the breaker outside the cell, rotate the racking screw as though racking the breaker to the connect position.
This process will expose surfaces inside the truck that need to be inspected and lubricated. Lubricate the
exposed parts; specifically the entire Racking Screw (4) and Position Release Shaft (5) assemblies during the
operation. Inspect breaker locking tabs (3) and Secondary Locking Tab (6) for any damage. Return truck to
disconnect position. As a precaution, do not operate the breaker outside the cell unless the truck is in the full
disconnect position.
