All maintenance that requires removal of the cover of the unit should
only be done by properly trained and qualified personnel. Hazardous
voltages exist inside the unit. Disconnect the supply from the AC mains
input before performing any maintenance. Service, fuse verification, and
connecting of wiring to the chassis must be accomplished at least

The OFF position of the front panel power switch does not remove AC
input from internal circuits or input terminal blocks. Disconnect external
AC input before servicing unit.

For safe and continued operation of the SGI Series, always operate the
unit in a temperature and humidity controlled, indoor area. Exposure to
conductive contaminants or corrosive compounds/gases that could be
ingested into the chassis could result in internal damage. Keep the rear
