Warning: The replacement procedure described in this section involves the removal and re-
installation of threaded fasteners. The installation of over-long fasteners is some locations can
penetrate and damage the underlying equipment or short circuits that are energized at 90 Vac
to 264 Vac. The potential damage can affect equipment performance; the potential shorting of
the electrical circuits can produce shock hazards that are capable of causing serious injury or
death. Verify that threaded fasteners of the correct length are installed in the equipment.
When fasteners are removed, store them with the related components for re-installation. Refer
to this procedure to verify that only fasteners of the correct length are re-installed. Re-install
threaded fasteners slowly, and verify that they do not contact underlying equipment.
!
Warning: The G50 and the G60 S contain hazardous voltages that can range from 90 Vac to
264 Vac. These voltages can cause serious injury or death. Only authorized service personnel
are permitted to remove protective covers and access the energized components of this sys-
tem.
